All of them are already burned in, given i bought H7 second hand with used tubes and my tubes were already used in my TA-26S.

Adapter arrived yesterday. Currently trying with a TAD 6sn7gt (new production) that I liked with my Xduuo TA-26s. Running along with a RCA 6as7 in the Eufonika H7 all I can say at the moment is that I like it too. Do I prefer it over the 6n1p I was using since now? I don't know yet, maybe the...

I'll do when my adapter arrives, already ordered.

So, if I understood correctly, is perfectly safe to use them via adapter without fearing of breaking something in the amp itself, great news! I know have a few more options to change the sound without having to spend a pennie in new tubes,just the cost of the adapter. Any recommendations on...

Thanks a lot for your answer, I have a few spare 6sn7's I'd like to try , but I want to be sure first I won't damage the amp. What data do i have to look for in both tubes datasheet (original 6n1p and 6sn7). Does the adapter take care of the different voltage, I'm rather new to tubes and it's...

May I use 6sn7 tubes in a H7 via adapter as a driver tube without damaging the amp and not modifying it? Will I need a socket saver to be able to insert the tubes or just the adapter is fine? I'm thinking in some adapter like this: https://a.aliexpress.com/_EGX0T8R

Today I tube rolled a NOS russian foton 6SN7 tube in my TA-26s I just received and the volume was very low, I was listening just before with a new production TAD tube and volume was loud as always. I decided to try the other 2 fotons I've received and the same, low volume. I thought they were...

First time posting in this thread. I have new HD600s since like 3 months ago. Enjoying them a lot with xduuo Mt-602 hybrid and fiio k5 pro ess and q3 for portable, but I have to say that pairing them with recently purchased xduuo ta-26 OTL tube amplifier has revealed all his goodness. They were...

Few days with TA-26s, still with stock tubes. I have to say I'm blown away with this amp, either driving my senns hd600 and hd660 or as a preamplifier feeding a simple Fender Monterey the quality (and quantity) you get out of this is unbelievable. Rich bass,with slam,lots of detail, great and...

Stock tubes atm,waiting for some though Waiting for GE 6AS7GA NOS and Phillips 6080WC NOS as power tubes and new production 6SN7GT tung-sol and TAD for preamplifier. Are they any good? Anyone has any of these or proven them?

How Sennheiser HD-600 scales with my new TA-26s is just incredible, effortless fullness, bass slam and quantity, even treble extension is improved I'd say. I'm enjoying this combo a lot. It happens similarly with HD-660s but to a lesser degree, I guess having half of the impedance of 600s being...

For portable I use a fiio q3 with my senns, so for me is perfect because I don't have to change cables everytime or use one with 4.4 and the other with 6.3 as I did since now. Now I can use HD600 and HD660 indistinctly for desktop and portable use, so convenient indeed! Before I had to rotate...

By the way, I'm using my new TA-26s paired with a topping DX3 pro (1st AKM chip version). I also have a fiio K5 pro ESS. Which DAC do you think will have a better sinergy with the amp, I opted for the topping because it's not as analytical as the fiio, am I right or is the contrary preferable? I...

First thing I have noticed is more textured distortion on guitars compared to SS amps I have as well as wider soundstage. Bass is more present and organic too. Detail is a bit less though. All this is to be taken with a grain of salt, as they are from first hours with it and amp has to settle...

Thanks for your answer
