Audio Horizons TP 2.0 Preamplifier

I thought about them but will listen to the preamp first with my NOS tubes and will alter it later if I want to go in a particular direction.

I want to thank everyone on this thread for influencing my decision. I just today received my TP2.1R from Joseph and Victor, and my immediate reaction was astonishment.
This is an absolutely wonderful Preamp. I just played music non-stop...music I thought I knew very well. Cliche as it may be, I had amazing decay of notes, clarity of even the breath before the flute was played, depth of stage and sweet tight bass and the subtlest of instumental nuance just gave me a Yo Yo Ma concert in my living room.
You guys really got it right. This is one excellent preamp!!!!!

Congrats. Eddie any comparisons to other preamps you have owned.
Does anyone know if one can use two different pairs of tubes without problems or do you have to go with an identical quad.

I tried two Siemans cca's in position 1&3 and two Siemans e88cc in positions 2&4. This worked quite well, though the matched quad of cca was slightly better. I also mixed EH tubes with Siemans - it was not as ideal but still OK

I've tried a lot combinations, including amperexes and telefunkens. I think all Siemens is best. Two Siemens gray plate E88cc's in the 1 & 3 positions and telefunken E88CC's in 2 & 4 did sound very dynamic; however, it seemed to flatten my already flat soundstage. I think as a concept, however, combinations worked very well in the TP 2.0.
