Audio Horizons TP 2.0 Preamplifier

Joe,
Yes, I recall us both putting in the cca's. I also turn my preamp off at night and the average daily use is also about 6 hours. They do still sound very good. I'll look into a used, calibrated B&K 606.

Hi guys,it's been awhile.Recently acquired a quad of 6H23 Russian military tubes.Manufactured in a collective factory in Kaluga,not Kahula(joke)they are a drop-in replacement for the 6922 tube.Sonically they are as good as my Siemens ECC88's but do not have the finesse of a CCa.For something different and everyday use they're a perfect fit.

It's interesting to me to note that recent comments on this thread concern tube rolling.

One of the attributes of the TP 2.2 that most enthused the PositiveFeedback reviewer (see my 6/5 post for link) is the responsiveness of the TP 2.2 to tube selection.

We are living what the reviewer described.

Whatchu talkin' bout, Mark? You sold your preamp. Are you going with The Dude now? I would love to hear your impressions. (o:
