Joining the Xduoo TA-26 club soon as I have ordered this amp and can't wait for it to arrive.

Since I already have a very nice collection of NOS 6080/6AS7G/5998 and 6SN7 tubes, I was looking for a DV or this as my second OTL that uses the same tubes to use as my everyday work amp to drive my HD600, HD650, R70X and Grado SR80X.

I also intend to drive my SS class A headphone amp using this as a pre for my Ananda (coz I just don't like direct DAC to SS amp anymore, spoilt by my Felika Euforia pre to my speaker power amp to drive the extremely tough to drive HiFiMan HE6SE which sounded way better to my ears than the Arya and was brilliant with the Susvara as well.

Down Under!
Couple quick questions for anyone that owns an Xduoo-TA 26.

1. How many inches in between the two handles/rails flanking the tubes?


2. Anyone use dual 6SN7 adapters to run tubes such as 6J7, 6C5, etc?

Before I make this purchase, just want to verify my dual adapters are going to fit in between these rails.

Thanks in advance!

Oh and a better pic of the tubes I'm currently listening to for those into them. NOS Melz 1578 + MWT/GEC 6080/A1834 stubby, maybe I should get a riser for at least the back, looks funny being lower to me (Feng Shui 'n all) but then I prefer the look of ST style tubes.

It's here, the TA-26 and first impressions are extremely positive. Love it with my HD600 and R70X which absolutely demand an OTL and frankly are pretty much nonsense with most SS amps I have tried. The TA-26 is not the most resolving amp, atleast with the stock tubes, but then it's still very new and hardly burnt in. One thing that really stands out is the headspace. It even expands the relatively closed HD600 out of my head in all directions. I even tried the pre amp function to my SS Headphone amp and it was again mighty impressive driving my ER4XRs, which sounded the best ever on my SS amp. I plan to stick with the stock tubes to fully run in the amp and then bring out my better tubes once it is ready.

I am doing the same with my low impedance headphones pre amp to Topping NX7.

TA-26 is my first OTL. HD6XX on TA-26 is the best I heard it sound.

Nice! I'm on the same boat, I'll use the stock tubes for a while, make sure they are burned in then roll them. I don't have much experience rollings tubes so I don't know what I prefer. Got a military grey glass RCA 6SN7GT or VT231 with an RCA 6AS7G from Brent at Audiotubes, waiting for them to ship but I'm in no hurry. Even with the stock tubes, the experience is very enjoyable.

…it will get a lot more enjoyable with the RCA ‘munitions’…👍

Anyway couldn't resist a tube swap and swapped the power tube to a Chatham 6080WA. The immediate improvement seen is the reduced the mid bass bloat. THE 608O tube sits deep down inside the chassis but I am finding this amp to be a lot cooler running than my Feliks Eufora running 4 tubes.

HD6XX, at 300 ohms, will always sound its best with a high output impedance OTL ☑️.

Yes, I heard that so many times but experienced it very recently. I have owned HD650/6XX for more than a decade and bought OTL just a few months ago. I can't believe how I ignored it all those years.
it's because I spend very less time on my desktop listening to music. I am a portable user and invested mostly on DAPs and portable DAC/AMPs. I am really excited to try the upcoming XD-05 Pro.

Just got this NOS Mullard 6080 for my TA-26. I'm still letting it cook for a bit but from what I have heard the bass is more substantial and extended on my HD6xx and DT770Pros.

What tube are you using with the Mullard 6080?

Just the bog standard one that came with the TA-26 for now. Probably a JJ? Got my eye on a couple of NOS Sylvanias for next month though.
