Audio Horizons TP 2.0 Preamplifier

Sherod , glad to hear your up to par.
Go play your White Christmas by the Drifter's.That should get your feet tapping.

You've got a good memory, Goldeneraguy. Good idea...every time I play the Drifters White Christmas, it does put me in a good mood.

I recently purchased the TP 2.3 preamp. I had some Siemens Cca ready to roll. I was surprised with the results. The synergy was not working with my system. I have had good success with Amperex 6922 and Philips SQ -- rotating between 1 to 3 and 2 to 4 -- while I await the delivery of other tubes. The TP 2.3 is starting to sound like the great amp others have written about on this thread.

Regarding tube rolling, I have read of success with Amperex PQ White Labels. I have been in touch with Joseph Chow who has suggested I try Telefunken (I assume E88CC) in 1 and 3 and Mullard CV2492 (preferred) or Amperex (not yet specified) on 2 and 4. Does anyone have experience with this? Thanks for any helpful suggestions.

When I owned my AH I found that maybe one in 5 sets of Cca's even from reputable sources sounded amazing and the rest just OK. These best sets of Cca's beat everything else, but the rest of the Cc'a for me were beat out by Amperex White labels. Hope this helps - its a great preamp!

Gammajo,

That's interesting. I tried a pair of Siemens Cca and they did not work for me in positions 1 and 3. I am now using a pair of Philips SQ in positions 1 and 3 and they are very good. I have other tubes coming to compare.
