Looking good these days Thomas, I’m also liking your videos more every month, you keep getting better!

Hi Thomas go glad you have time to review this, you are one a few (Steve, Sean) who convinced me to try tubes, now have a Bob Carver 275 and it helped my B & W 803s speakers bring that warmth (not as bright), looking forward to going with class A single ended. Take Care

Never owned a tube amp, but i LOVE all the designs, works of art

Thomas, you've been putting out some of the best and most engaging content right now and for quite some time, very few people are as genuine and knowledgeable. I only wish you lived down the road so I could hear some of the great stuff you test out and trade stories! Best wishes from the UK.

Hi Thomas! Awesome looking unit. Absolutely love the price tag! Awesome aesthetics.

Thx for the intro to the A12. I found someone here that builds tube amp so it will be interesting to find out how they compare.

Funny you posted this now because i got my A12 about a week ago, and your A10 review helped make me make that choice. If this video was posted a few weeks earlier that would have made up my mind earlier lol. I was previously under the impression they were essentially the same save for the 12AX7s and the wider array of options for replacement tubes for the A12. Glad to hear that it is better all around than the A10. This is my first foray into tubes and I am loving it so far. Thanks for your content.

Great channel really enjoy your reviews and presentation.....

I'm just setting up the A12 today, thanks for your great video on it.

You are a smart guy.. I like this review.

Thanks for another good /informative video, I could hear the difference, and have a preference for the A12

Yes, Finally! This is the amp I have been looking for.

Very good! Might try one! Thanks!

I use mine with Klipsch Heresy speakers and dedicate this system to the mono set up, due to room size,. speaker placement is less restrictive, sounds great

Correction: Misunderstanding between me and Mr. Vintage, he did not open and measure the voltage of the 12AX7, sorry. Keep in mind that the difference I hear could simply be the difference in tubes but not the actual machine. www.china-hifi-audio.com/en/reisong-tube-amplifier-boyuuragne-audio-c-48/reisong-a12-12ax7-el34-tube-integrated-amplifier-single-ended-class-a-boyuurange-p-2347 Non-affiliated link

Excellent video. It would be great to hear your take on the Boyuurange 300b amp. I home auditioned it with heresy 4. I loved the sound. More so then EL34. But i returned it only because the tube sockets were a bit too loose. The 300b tubes could easily move within the socket. But it would have been a keeper.

Thomas! I've been a musician all my life. 10 years ago I decided to get into hifi....I've always played tube guitar amps so no brainer to get a tube integrated. Only reviews for tube integrateds started at over 5000$. It was discouraging! You my friend are the king of low cost good quality tube amps! It brings me joy to see you filling this space so well.

Hi Thomas, Thank You A LOT for this comprehensive review ! Highly informative, esp. for "Tube Amp Beginners" like me :-) ! Due to this, I recently ordered the A12, and it did not disappoint me. The stock tubes are ok for the price and are already sounding good. BUT when I changed the tubes to 2x 12AX7A-C premium selected ones from TubeAmp Doctor in pre, and 2x matched TungSol EL34Bs in final stage: MAN - it really blew me away ! Super detailed mids and highs, great 3D soundstage, and a Bass so precise and punchy that I think I use a solid state Amp with substantial more power ! On top NO audible hiss, hum or noisefloor; and my speakers are 96dB @ 1W/m ! Absolute fun to listen to, also longterm, I did not notice any flaws, distortion and whatsoever. And I listened to many genres of music. It seems the schematic has some slight changes to the previous versions. THIS is a real bargain to start with- I paid only 416€ , shipping from EU warehouse included especially if you consider that you have the FULL SELECTION of 12AX /ECC83 preamp tubes to fine tune it to personal preferences! THANKS again for your expert tip !! Think I will never sell this nice little amp.

Nice amp !!!! I run a single ended 2a3 tube amp with a tube preamp by Cary.....ae3 which is good....but that Reisong sounds great....a must for better tubes to bring out the best !!!!....Ed in New York....😎

I recently set my a12 up with klipsch rp600m and it sounds great. Just ordered a matched pair 6ca7 electro harmonix big bottle tubes .My first tube amp can't wait to hear the difference. The only thing lacking was treble on stock tubes

On my A10 I rolled all the tubes. EL34s are easy. I went with the Tung Sols and Telefunken EL34s. Tung Sol gets my vote, much smoother and cleaner than the Telefunkens. I also did the following: Stock Voltage amp tube 6N2J, replaced w/NOS JSC Voskhod 6N2P-EB/6AX7. Stock Rectifier Tube 5Z4PJ, Replaced w/NOS Mullard CV 1863 from the 60s. Sounds amazing. One caveat, the Mullard is taller than the stock tube and interferes with the tube cage.

Thanks! EL34 is famous for the mid-range... In my experience, signal tube rolling will change the sound more than rolling power tubes

My Asian brother uncle guy. You're perfect. This was a great video. Aesthetically and sonically pleasing.

I actually had some time to do tube rolling on this amp. Replaced the EL34s with J&J KT88s and also replaced the 6N2s with Gold Lions 12ax7. The last change had a large impact on bass/treble response .. I actually like this configuration more for rock and almost all other genres of music. Yet for classical I keep coming back to the EL34 tubes. I also hooked the amp to a function generator and oscilloscope and was really impressed with what I saw. There were some even harmonics but overall the baseline was less than -80dB. People have complained about the baseline in this unit but I think it is superb! I actually love my Reisong A10 and think it will go down in history with likes of the NAD 3020. Affordable and delivering huge sound !

I bought a tube amp that looks like(chrome chassis, size and trans covers, etc) the A12 more than 5years ago, I converted it to accommodate the KT88 to increase the power output to about 10-12watts/channel. That changes the character of the sound totally because of the tube rather than the power output.

Thomas with gel-ed hair, smart 👍👍👍

Hi Thomas. If you’re looking for suggestions for products to review, I’d suggest the Willsenton R800 (845 version). Also, maybe some decware amps..? And would be great to have a video on matching speaker wire with amps and speakers. Thanks!

Great job Thomas. I love tubes too. Have you ever reviewed any gear with EL84 tubes?

I have the A10 and found that I can swap out the stock signal tubes with 12AX7 tubes by using an adaptor.

i was even able to hear it through your recording, the a12 is really better in the mids!

Hi Thomas. If Most audio reviewers, like yourself, heard both the Reisong A10 and A12 with the stock tubes, would it be safe to say that they would think both of them sounded the same? In other words, are both amps the same except for not needing tube adapters on the A 10 for tube rolling? I LOVE your videos and the passion you put into them. Keep up the FANTASTIC work!

Due to budget constraints I want to keep my tube amp in the $500 range. The A-10 and A12 are about $50 apart. Thanks for the review. I will go with the A-12 with tube upgrades down the road. Also Amazon will be the shipper and if there's a problem I can ship it back without the hassle.

If you already have the A10 just buy 12ax7 adapters on ebay. I did this to mine and swapped to some Genelex Gold Lion 12ax7 tubes and got a dramatic improvement.

You can use aan adapter to use 12ax7, I'm using Mulard 12ax7 and Golden Lions K88

I never know how good it can be until I put NOS Mullard EL34 and NOS Telefunken 12ax7 on it.

I would love to see a reviewer challenge. For example, $10k total budget to play Pink Floyd - Time in a 20’wide, 30’deep, 9’ tall room with carpet and a couch. You pick the format and can add cables, room treatments and so on as part of the total budget. No headphones and no used gear. Each reviewer to post their entry video on their channel with a link to the original video posting the challenge in the description with a list of the build and prices. Only one complete build; not a bunch of options in that price range. Not required to actually build the system. Winner is the video with the most likes.

Needs a couple of more inputs ( 2 single ended RCA and 2 balanced (XLR) ) Auto biasing and yes, a remote would be nice.

The tease of the modded focals is real 😍

Curious about Single ended vs. Push Pull tube amps. I have the Push pull MT 34 version of this which is fantastic. Very good on vocals, even male vocals. Also, very good on string instruments.

Thomas - I really enjoy your channel. I am new to tube amps. I bought the A10 a year ago and love it. What would you recommend for a tube upgrade and where to purchase them? Thank you...

Hi Thomas, I just bought a A12 and I am looking forward to listening to it.

Thanks Thomas.

Enjoy your talks , very easy to listen to . My simple question is for an ‘entry’ tube amp purchase I’m caught between the Reisong A12 or Willsenton R8 . Is upgrade to Willsenton that strong ? I have average efficiency speakers with a solid state marantz and toppingD90 . I’m looking for a ‘softer musical format’ strings vocals etc . Again keep up the enjoyable talks .

Hi Thomas. I own a Sparks (Cayin) MT-40 integrated tube amp. And wondered if I could get better sound quality by switching out the EL34 power tubes to say KT77’s? Some people I have followed on different channels have said the KT77’s and KT 88’s produce deeper bass and high’s with more clarity. Would a change like this in any way compromise any other internal components within the amplifier?

Which EL34 tubes are used in the A10 for this sound demo? I do prefer the sound of A10 here, but that is probably due to the upgraded tubes. As always, thanks for giving us one of the best audio review sites on the web.

I bought the Reisong Boyuu KT-88 amp from China Hi-fi. I really don't understand why that amp is not getting more attention. It's got enough power that you don't need as efficient speakers and it has some good dynamics. What is it about the specs that are turning people off from it?

A10 sounds more holographic but the 12ax7 tubes are easier to find or change

👍 I THROUGHLY ENJOY YOUR ENTHUSIASM 😁😍😍😍

I find almost all reviews are on the A10. I am glad I went with the A12. One thing I will state is with my RF-7 IIs 6 watts per channel can annoy my neighbors.........and has......

Great Review, as always! How about using the A12 as a preamplifier to drive speakers below 90 dB via the power of a power amp or integrated amp?

Given the very simple topology and the point to point execution I feel it would be easy to ascertain and interesting to hear what has been modified apart from the preamp tubes and their sockets.

Good morning.. I always love tube amplifier

I changed the retifier from 5Z4P to a 274B and found improvement on speed and clarity.

Thomas, did you say Mr. Vintage found that the 12AX7s in the A12 work at only 6 volts? (Assuming you mean he measured the plate voltage and not the heater voltage) If so that is very interesting. Normally they can be used with anywhere between around 90 up to 300 volts. Running them at such a low voltage is called "starved plate," it's quite uncommon, but some people really like it. Would be an interesting experiment to try 5751 tubes instead of 12AX7s if you haven't already. 6N2P-EVs, 5751WAs, and 12AX7WAs are the heavy duty military grade versions available, and might be worth a try too. A bit off-topic, but have you/will you ever try any Luxman tube gear? I heard the LX-380 integrated amp over a year ago and still the experience has stuck with me...

Thomas, a while back you mentioned that you put a platter under your speakers-like a cutting board? Is this wooden or another material and where have you purchased these?

Very nice content @Thomas

Hi. I have a Simply Italy too. Together with quite efficient Cabasse speakers.I use Gold Lion tubes. What tubes are you using? Thank you.

There are these tubes left to try on this amp..........6CA7 GE ( fat boy ) and 5751A triple mica , black plates............ Maybe it's possible to buy an A10 and modify the pin out to 12AX7/ECC83 ( I don't know if schematics are the same ) CV1863 may be better than the china made rectifier.... OPT and power supply are limiting factors for this SE amp but for the price one will already hear the potential of this amplifier mode.........

Hi Thomas, your take on the A12 vs Muzishare X5 ($800 ish) and the Deckware super zen ufo ($995)? Thanks!

Ahhhh...Focal! I have the 807W. I have wondered how they would sound if modded out and if worth it? Any thoughts on Omega Super 3 High Output Monitor with low power amps tube or otherwise?

Hi Thomas. Could you do a video about which speakers are better with tube amplification, full range drivers or with cross overs

The 12AX7 will run 6 volts because the heater is center tapped. You just jump pins 4 and 5 and the other heater pin is 9.

Thank you Thomas. I wonder if these will pair well with the Triangle Borea BRO3

Any chance of reviewing Raven Osprey or Raven Nighthawk with matching Celeste speakers? Not many used ones for sale ever and what few reviews I have found say it sounds better than their current system that is many more times the price.

I had to mod the heck out of the A10 to make it sound good. It is not 6 Watt, tops 4 Watt but the first Watt out of the box sucked. In fact I changed it into a A12. Without the mods internally the tube rolling is not really worth it. Out of the box it only has muddy bass.

Thomas, how would one be able to use headphones with this unit?? Or, is there another tube integrated amplifier that has a headphone jack Respectfully Mike

Hi Thomas, always enjoy your videos. Can you recommend the best tubes for my Musical Paradise MP301, please? I am using the JJ 6L6GC and the inhouse preamp tubes. Many thanks.

Hi Thomas, alright i got Zu audio omen mk2 dw coming in june and i am looking for an integrated amp for them thats less than 1000 dollars. any suggestions

i have to say the A 10 after my improvements i really enjoyed for a while, but the A 12 whas a huge disapointing in compare , no improvements at all , only disapointings , thats what i could read from other peoples experiences , finally i bought a McIntosh MC275 VI Tube Stereo Power Amplifier and woooow i need no other , i bought it 2hand for 440 € and not regret it ,only enjoy it more and more

Hi Thomas! Have you tried running the A10 using adapters from 6N2J to 12ax7, and then assessing remaining difference? I would strongly recommend that! Adapters 6N2J to 12ax7: 14$ at ebay..... I use Hi-end 12ax7:s in my A10 using adapters, Psvane 12AX7-T-MII/2 (=ECC83) matched pair 85euros , and the improvement in detail and resolution was substantial over the 6N2J:s. I would guess it is hard to justify the almost doubled price for the A12 after such an upgrade of the A10.....!

You mention rolling the smaller tubes as well as EL34. Which tubes?

Hi Thomas. While you get to test a lot of amps what do you use for YOUR everyday system. The Doge 10?

Whoa: The price has increased twofold, Thomas.

Hey Thomas. Moving pretty quick. On Monday I will order either Doge 7 or the new Gustard X26 Pro Dac. Which is solid state but has crazy performance and engineering. Thoughts? Tubes vs probably far superior overall design.

It's a shame they didn't go with the 12AT7 instead of the 12AX7, it's a better driver tube for this purpose. There would be many, many more NOS tube rolling options that are reasonably priced than the 12AX7 which is used often in guitar amps and thus nice NOS 12AX7 tubes are quite costly. I've seen the schematic for the A10 and they're just paralleling the triodes for the input/driver tube and the 12AT7 would have almost as much gain but more grunt (lower plate resistance). If I bought one of these amps I'd see it as a tube amp mad scientist's experimentation kit.

I’m curious about what do you think guys about Bang&Olufsen 😅

Yes, you are right. No remote is indeed a deal breaker. Well... maybe. I’ve been wanting to set up a stepper motor for my vintage Marantz

Hi Thomas. I wanted to get your opinion on Skunkie Designs Electronics and her opinion that the A12 is basically not a very good amp without her suggested mods? Thoughts?

The videos we want!

Can the Reisong work with 6 ohm speakers like the Monitor Audio RS6?

As a burgeoning Audiophile I have been putting together an audiophile system bit by bit. I have my Logitech speakers (powered- bass module and 4 cubes) hooked up to my Acer laptop. On Tom's advice I have upgraded the speakers wires to the Monster's Cables which REALLY brings out the BASS and 3D surround sound aspect of the soundstage. Any ideas to bring my Audiophile system to the NEXT LEVEL would be welcome!

If your some body who loves vocals you need a tube amp

I have a Simply Italy on order. Would you say it's better than Cayin cs-55a in Triode mode? 12 watts vs 18 watts.

Amazing price point, from what i got from your review is pair with a neutral effeciant speaker 😃 Thanks Thomas bro3? I had a chance to buy the focal 936v and passed they needed new tweeters ehaaa should have bought one state over from me in Tenn 900.00US !

Thomas, apologies but I did not know how to send you a message privately. I have a Reisong A12. Happy with it and my Klipsch Forte IV and Burson Composer DAC. Question: Is there a sound quality advantage by going to the Willsenton R8? The A12 is plenty powerful for my room and gear. Just wondering if soundstage, etc. are significantly improved by the R8.

Do you recommend adding a REL sub to the A 12?

Thx. Just bought the a10. Is there a phono preamp you suggest for this ?

I have enjoyed the A10 for almost a year but have just taken delivery of an Elekit 8600 single ended 300B. It’s a well reviewed higher end amplifier so I’m interested in how different it will sound from the A10. I enjoy your reviews Thomas!

Who's the manufacturer of the diffusion you have on the back wall?

Hi Thomas:Heve you ever heard of the Eastern Electric Minimax tube amp,this is a must have for you,what this amp does is hard to believe,check it out dude!

Sounds like an amp you may end up with later on in life when the ears have gone! Have you tried the Sophia el34 or kt88 with the Doge 10 and if so did you hear a marked improvement?

I have the sound artist version which is wired for 12AX7. Replaced all the tubes and the caps with Russian PIO, it sounds great with a pair of Heresy III.

Those are low power amps. Tubes can give excellent sound, but any stereo needs power to punch out the thud of a bass drum. The peak power this requires instantly will exceed the amps. Tubes operate at high V, but only mA. For the bass drum punch, A are needed, which exceeds the capabilities of the tubes.

Great review Thomas. I've seen you unbox a few thing using the steak knife. Might be time for a manly upgrade. :)

Hi, good reviews. I found in Amazon a Boyuu HiFi that goes for $441 cdn vs the A12 at $689 cdn. The only difference is 2x 6N9P for HiFi vs 2x 12AX7 for the A12. Can you educate me on the difference ans if it worth the $248 difference. Thanks!!

I just Googled this exact topic yesterday. It must be a sign

What is the regime of work of El34? Triode or Pentode?

I have your Resisong 10. What output should I use For 6 ohm speakers? 4ohms or 8ohms

I would not even consider the A12, being twice as expensive while being exceptionally close to the A10 designwise. 25$ for adapters to 12ax7 pinout is a sensible way to go.

“TEDDY-BEAR” THOMAS! I like it
