Willsenton R300 Plus Review: More Junk Bling

In this video I do the anticipated test of the Wilsenton R300 Plus, which promises to resolve all the problem with the power supply and poor quality output transformers than plagued the earlier version. Sadly it has other issues and is just more of the same junk. It's really sad watching people throw away money on this garbage, that is easily tested as being substandard HiFi gear.
The 300B is a classic direct heated triode that some say is the best sounding audio tube ever made. This amplifier has gotten a lot of positive reviews from YT influencers in the audiophile world and I do not understand how anyone listening to the output of this amp could say this.
Edit: I changed the title and thumbnail after being accused of being a racist bigot. The term I used is described on Wikipedia as "The phrase was coined by Zhu Rongji, the former premier of the People's Republic of China....is widely used as a metaphor for shoddy work". If you see earlier this week, I have nothing but praise for the new Psvane tubes, have praised both the revised R8 and the Muzishare X7. Reporting factually what a product is and pointing out bad design, parts and construction has nothing to do with the race of people involved. I have also pointed out issues with made in USA products so just stop this nonsense.
I pointed out all these flaws directly to Willsenton on the previous R300 I reviewed and they chose to not address them. This was their decision and it's not racist for me to point out they didn't fix all the flaws with this amp when they "redesigned" it. They just sent more free samples out to the same reviewers who previously praised it. It's cheaper to hype a product online than actually manufacture a quality one.

Sure glad I saw this, as it appears you read my mind concerning 300B amps. I've been very happy so far with my R8 (revised) with the stock KT88 tubes, although I have gotten a quad of Mullard EL34 to try. I really had no need for the R8 since my little Cayin MT-12N (EL84EH) at 10 wpc is more than enough for my Zu Audio DW6 speakers at 97 dB sensitivity, and sounds great. But watching all the videos I got the itch for a KT88 amp and felt confident with the Skunkie corrected R8 and was not disappointed. But being the gear head I am I now have the foolish urge to get a 300B and was considering the R300 due to all of the positive reviews. This video seems like it was aimed directly at me and has given me an attitude adjustment, lol. Maybe someday I will get a 300B amp, but it will not be this one. Thanks for saving me money and potential grief.

“Get a Dennis Had…” already have one. Also have the Musical Paradise MP-301 Mk3. Big difference in price but one I can listen to all day without fatigue and hate switching it off. The main reason I didn’t buy the Willsenton a couple years back was because it’s very big and heavy (even tho the pundits praised it). I prefer the form factor of the smaller amps. Nice and tidy on the shelf. Thanks for your time dissecting this amp. Much appreciated.

Steph, I know you have gotten flack in the past for these types of reviews, but I believe that you are doing the Hi-Fi community a huge service by testing and reverse engineering these to help folks not get taken as well as finding the occasional gem...or at least the potential of one. I would love to see some doing this for every cheap amp that comes out. I realize that this is not something that you want to do, but something like what Erin's Audio does for speakers like what you're doing occasionally would make for a god YT channel

A nice honest review with technical data that does not lie. I don't know how this equipment is appearing on the market with poor outcomes. I agree with the statements you made reference the design of the power supply. What is the point of putting two tubes in parallel when they're not needed. If each tube was to drive each channel that's different matter. It appears this manufacturer is trying to hoodwink people making it look like a good design. I know your channel has a wide scope of viewers. Viewers with electronics background understand what you are talking about. What I like about your channel is how you explain your outcomes from basic level and advanced level. Keep up the good work. Looking forward to reviews of more of your projects Brian

My Willsenton R800i-805 came with the starter Shugey carbon plated 300b and the amp recommended bias is 120mA. Those Shugey tubes are rock solid and they never fail. I don't dare to roll them with Western Electric 300b that has max recommended bias of 70 mA so will get a pair of Shugey 300b-z for my R800i-805.

Hello! I have a small suggestion. Make yourself a single-ended amplifier for 2A3 or 45. Without feedback. And check out the sound in comparison with pentodes - tetrodes. If the sensitivity of the acoustics is above 90, then with low power there will be a completely normal sound volume. The comparison of sound quality is very interesting.

@@SkunkieDesignsElectronics Thank you for your replay, I read somewhere that the transformer was upgraded to a z11 and whilst I cannot fully verify this, I did own the previous version (non-plus) version, and compare to the plus version, the Plus version definitely sounds like it has more power, thicker mids and better bass (using exactly the same set of tubes) at the exact same volume point . I got the Plus version second hand at a very bargain price here in HK, and so to me although knowing that there's issues with the first version as you pointed out, I thought maybe they fixed it in the Plus version because I do actually really like the sound of this amp... Having a small apartment here I don't have too many choices for affordable 300b amps with this size and weight since I often have to move the amp, other potential 300b amps from other companies i can find here are all over 30kg like the muzishare x9 so that's why I decided to go with this amp knowing that there maybe shortcomings. So ... without knowing what plate voltage is in this amp, would you recommend to under-bias maybe 1 click if I was to keep using this amp until I find another better amp to replace ?

How about some of your picks of amps that are worth buying, getting sick of these hype guy reviewers, every week is a new “ultimate, best ever blah blah.

Not at all. That’s why I’m asking . I got a mortgage and kids…. I can’t spend 8k on an amp…… running 97db set up. Bi amp. Looking for amp for mid and tweeter

Honestly that little Aiyima A70 class D amp upgraded with some sparkos op amps sounds MUCH better than an R300

British Audiophile has no clue to what is good with the R300/Plus and I have commented to him.
