Thanks for your kind comment Marek ;)

Hello and thank you!

Thank you @@EBSELPROAUDIO :)

Thanks for the tip! I will play with some other tubes for sure :)

Thanks for the information!

Hope you'll enjoy it!

@NormcoreGreg It arrived in Beautiful Sri Lanka. Lights are a bit bright for my taste. Wiim Pro, SMSL SU-1, tubes, NAD C352, B&W 602S3. Pretty neat sound.

@@NormcoreGreg is there a break-in time? Does the sound quality improve?

@enricolisk1357, I hope you’ll enjoy it. Agreed about the lights. Btw. I’ve never been to Sri Lanka but must visit it one day as I heard it is beautiful.

@NormcoreGreg Do let me know. I do curated trip planning as a hobby for my friends. Can help u with reliable & courteous inland travel & hotel options. recommendations.

What exactly don't you like? Maybe some of those vices can be remedied by different tubes?

@@NormcoreGreg it's hard to explain, the sound became unpleasant. I assume it sounded like the distortion on some frequencies (possibly upper midrange). I haven't experimented whith the preamp a lot, maybe someday I'll get back to it

I couldn’t find any on Aliexpress. Can you share a link to the dynavox preamps? I’ll see what I can do.

Yes, they can.

In my opinion the headphone amp in the preamp I reviewed is just a convenience addition. I will be reviewing two dedicated headphone amps from Fosi soon, one of which includes a tube section, so you might want to stick around ;-)

@@NormcoreGreg Sounds good. I look forward to it.

@@alanrogs3990 I feel you Alan ;) I also prefer the natural glow of tubes. It’s like women with silicone… lips. You could probably unsolder the LEDs, but I’m not good at such things so I haven’t tried it. There’s no switch though.

Why do you think Russian tubes are good stuff? Most are just so so.

@@alanrogs3990 My experience with Soviet tubes has been extremely good. Those are old Soviet tubes, might be new production, but Soviet tubes. Do you actually own this device? To you have any useful comment regarding my actual question? Or are you just talking out of your a**?

@@wahid-lg1kk Yes, I have experience with tubes from all over the world. I have several hundred tubes in my listening room. I am not down totally on Soviet tubes. I have had experiences with 6c33c tubes, 12ax7 and several others. I just find them so so, but the old 6P3S-E seem to be okay. I don't need to own this device to ask you the question that I did. I also didn't need to answer your question. I simply asked you my question. You seem to be full or anger so I'll just stop here. Have a good day.

@@alanrogs3990 Most people online are extremely negative, and have a lot to say about things they know nothing about, and statistically speaking, someone asking so bluntly 'why do you think these are good, I think they are only so so' comes across as an entre to some negative interaction, where I am wrong because my opinion is different. This is a sickness in our culture. I apologise if you were not coming from that place. I have found Russian tubes to be far better then the Chinese and other stuff I can get here in Indonesia. I really like them, and feel they last a long time and sound great when burned in, they are reliable, and when warmed up properly, very delicate, much nuance, which I don't get from Chinese stuff. Some American milspec stuff is better, but hard to get, and very pricey here.

I treat this as a compliment :D

hilarious

@@NormcoreGreg As long as you don't get angry and turn green! You get a small amount if we buy it ... isn't that compromising you a tiny bit? Moreover, you looked at the components and build quality and didn't cover the important part, how it sounds. The tubes come from Russia ... is that a potential export embargo violation?

@@henrikcarlsen1881 these are all valid questions, thanks! :) As for the sound of it, I talked about it in my original review of this unit, which you can find here - kzfaq.info/get/bejne/rJx7qaWeprmpiXk.html. Regarding the commission (that I'm yet to see) and how it might influence my opinions - I'm an amateur "youtuber" and I do it purely for fun; I purchase all the gear I talk about with my own money (except for three pieces I recently received for free as review units) and make some research before to make sure it's not total crap; having said that I admit that a potential financial reward, however small it might be, may, even on the subconscious level, affect my opinions. But no one's objective anyway and we should always take any information with a grain of salt. Your last question about tubes from Russia - as a Pole I wave a very strong opinion about Russia and how it should be dealt with, especially given the ongoing war with Ukraine. However, I'm not sure such tubes are of strategic importance. Also, I'm not sure if they come from Russia or from some other ex-soviet country, e.g. Ukraine. I appreciate your concerns in this matter though.

​@@henrikcarlsen1881are you serious, there always has to be one

It doesn’t look like those opamps are swappable. At least not easily. But you can roll tubes - that’s what they’re for besides the look ;)

@NormcoreGreg i guess at this price point, rolling opamps is too much of an ask.

@NormcoreGreg Yes, will check on tube rolling. Appreciate if you can provide some alternatives for the tubes in an upcoming video.

Why not? If opamps are soldered to the pcb, then desolder and solder proper sockets to make further exchange easier. I've done such thing several times.

@@enricolisk1357, @dungysphincter7974 mentioned several choices in his comment to this video: "Here are some replacement tubes if you want to tube roll (GE 5670W, 6N3/6H3N/396A /2C51/5670. For best life, and lowest noise, I recommend the Soviet 6H3n-EB tube over the 6H3n-E tubes."

I was looking for this comment lol

You are kidding yourself if you think your brain is doing anything but sitting there being wet.

@@wahid-lg1kk You are kidding yourself if you think you have a brain.
