I am concidering almost exactly same thing. Not necessarily this exact tube buffer/preamp but some of this cheap boards.

What i am wondering is that does tripath amps benefit from tube buffers /preamps at all or do they actually give drawback in soundquality? I have not found clear answer to simple question. Is there one or is it about opinions again?

Could someone more cultivated audiophile enlighten me about this?

Maybe this will help; it is a video of my Topping TP21 T-Amp with a YiXin MDS-623 tube buffer on the front end. The sound is stunning. The tube buffer really adds a thick, lush analog layer that compliments the T-Amp highs and mids. The MDS-623 utilizes (2) 6N3 tubes which are Chinese equivalent of 2C51/5670.

Default Yes, with good tube buffer

I have tried various tube buffers with Tripath based amps. The best so far was with the Decware z-stage which manages to be very transparent and extremely musical. The other buffers sounded like they were adding a veil to the sound.

But with the z-stage it was magical.

I have been using a Yaqin CD-2 tube buffer in front of a Tripath 2050 amp. It really wakes up the amp.

Here's the thing...The buffer works best AFTER the volume pot. If you are using a tripath amp with an onboard pot this may not be possible. I used a 25K stepped attenuator in front of the buffer then into the amp.

Honestly, if you are going to DIY something I'd look at the Nelson Pass B1. My experience with the tube buffer was positive but you do lose some detail.

The tripath amps will always have buffering/impedence issues when used without a preamp, most have just a passive pot in front of the amp. Adding the buffer really drives the amp better.

Other amps like the Pass F5 are more immune to input impedence...but my tripath needed the buffer. And good tubes in the buffer but that's a different story...

I have been using a B1 Pass buffer (DC coupled with symmetrical supply and a 10K pot in front of it) with my TA2022 amp for some time now and I believe it is a killer combination as it has beautiful lush sound with amazing detail at the same time. One of the best sounding combos regardless of cost. Many listeners thought that they were in front of a top class tube pre/power amp combo and its all solid state. Highly recommended.
