ASR cares about transparency of sound. But that’s not the point of tubes.

I agree with what SoundMix said, I'm not an expert but the fact that I'm a physics student helps me to understand what those graphs mean and how a tube amp works. That review really seems to test this tube amp like a solid state amp, it gives you numbers. But for what is worth, numbers mean nothing in a tube amp because you buy it for its "imperfect sound" and not expecting an analythical sound

I did read this prior to purchase. All tube amps will show more distortion when compared to solid state, that distortion is the desired effect, besides they seem to be S.S. and graph fans. I'm a music fan and enjoy listening to music very much thru my THX 789"s, so this is a hybrid and the audible differences are more subtle. Hearing is subjective and i prefer options to tune music to my particular taste. First i found that ear pads made for substantial mods then dampening : foam, felt, cotton, and now tubes. As far as I know virtually all Guitarists use tubes. Enjoy your music.

I've tried a few different tubes with TA-20 and enjoying US vintage versions from GE, Sylvania and Raytheon. This seller at eBay has a good amount available: https://www.ebay.com/sch/spin4cards/m.html?_nkw=&_armrs=1&_ipg=&_from= Right now my favorite is a pair of Philips 6189W tubes that are working well with Grace SDAC Balanced. This amp pushes my dynamics (Fostex, Beyerdynamics and Sennheiser) and planar (HE-4XX and Aivas) very well and evenly on balanced output.

Thanks everyone for your inputs. Received it yesterday and immediately changed to JJ tubes. Wow love the amp, it’s very different from my THX 789 amp, can’t explain in technical terms but found it very smooth and fun. It is best with my hd6xx, dt177x and it’s ok with Sundara. Good with modhouse argon mk3... no hiss sound in any of the headphones. Overall very happy, thank you everyone!!!!

Glad you like it. The JJ will likely get a bit better sounding over the next 50-100 hours of use as they break in.

Not a true balanced amp? As the power output for SE and 4 pin XLR are the same.

What is a "Customized hi-fi capacitor" or a "professional volume IC?" Thanks.

I live in Sweden and Swedish voltage is 230V at 50Hz. No problem.

Hi. I'm this will be my first time trying tubes. I've read about the use of socket savers. Does this need them? Also if it does need them does anyone know which ones it needs?

Socket savers can be used, but you lose the tube guards on the TA-20. Unless you're planning on changing the tubes constantly, there is no real need for savers. If you do want savers, you need the standard 9-pin. Example: https://tubedepot.com/products/9-pin-socket-saver

Awesome. Thank you so much. I'm completely new to the tube world so trying to learn what I can

Hi Guys, My two cents. I purchased this amp though not through Drop. I really like this amp a lot. I have, among other headphones, the hard to amp-pair Fostex TH-900's. These headphones work wonderfully with this amp. As do my assorted Sennheisers. There's a caveat. You have to tube role immediately. If you purchase this amp, find a pair of ECC82 12au7 tubes online and get them. The Chinese tubes this amp comes with are only included to deliver this amp in working order but you can't really use them. They sound terrible so you can't judge this amp based on the tubes it comes with. Tip: I got a pair of JJ Electronics tubes made in the Slovak Republic (Slovakia). While I do intend to try other tubes just for kicks and giggles, these tubes work great and are inexpensive. Want a balanced tube amp? Get this affordable amp and get a separate pair of tubes and apply them immediately. That's it. My two cents. Enjoy your new amp!

Hi MastroiTek, I saw the review quite a while back and I am not bothering to go back to the review so I'm only relying on my memory. I think he mentioned something in the review about tube rolling but he didn't have any 12AU7 tubs on-hand. Z, as always, provides mostly positive reviews and most things he reviews are "then next best thing" because that's his job. He's a salesman and needs to keep his job, his YT channel and other social media interactions, relevant and with views and likes and helps him to get products sent for review. I follow Z and enjoy his reviews but I had to wean myself off of his influence on me. With regards to the actual stock tubes of the TA-20, they are the most basic Chinese tubes, provided only to ship the amp in working order. When I got the amp, not via Drop, I was very disappointed and only used the THX amp for a while. When I finally changed to the above mentioned tubes it became a totally different amp and became very enjoyable for my dynamic headphones. The biggest difference was with the Fostex TH-900's. I use these headphones on the TA-20 only now. My other dynamic headphones, it depends on the music and I switch back and forth a lot. So I must disagree with Z's assessment on the amp based on the stock Chinese tubes. Tubes make a huge difference and I've only rolled one time on one amp to come to that conclusion. I will be rolling new tubes in the future and try some even more expensive selections. The only thing holding me back at the moment is a considerable investment in a new bangin' home theater which is consuming all of my resources at the moment. But I stick to my guns on this one. Yes: Get the amp. New tubes: Required.

Hey thx! I also noticed that normally Z has many nice things to say about a new product but I remember that for the TA-10 he clearly said that the tube was crap (or almost), while fot the TA-20 he said that is was fine, not great, but still enjoyable. That is all. For now I will just try the stock tubes, but I plan to buy some better one with a new dac and cables in order to use the balance output of the TA-20. Thx for your advice :) Slowly I will reach my "dream" setup (the problem is that there is always room for improvement haha)
