Tube Buffers worth it?

I've owned the MF X10v3, and auditioned the Yaqin single tube buffer. Currently using the Audio Horizons TB 5.0 tube buffer. What you get with this unit is the ability to try different tubes (not so with the MF), and gear designed by folks whose primary business is building high quality tubed preamps and phono stages. Running between my SS pre/pro and amps, it is a definite improvement. AH offers a 30-day in home trial, so you can check it out in your own system, in your own time. I'm not affiliated with the company in any way.

Dmm53 -- if you get the Audio Horizons TB 5.0, do yourself a favor and upgrade the stock tubes. Victor of AH recommends vintage gold pinned Siemens E88CC. I have some on order. In the meantime, I have auditioned about 5 or 6 types ... including Amperex orange globe logo gold pinned 7308's, Amperex Bugle Boy, Siemen-Rohr 7308 steel pins, '72 JAN Sylvania 6922, and a couple of other current production types - Chinese and Yugoslavian. BTW, contrary to what folks say, some of the new higher end Chinese tubes aren't bad. For my system, and my musical tastes the gold pinned Amperex 7308's sound the best ... great tonality, sound stage, imaging ... very smooth and musical - top to bottom. It's hard to imagine that the Siemen's can beat these. Another suggestion: pick up some tube dampers from Herbies Audio. Seems to tighten things up a bit ... making the sound a little more coherent. Good luck and happy listening.
