Audio Horizons TP 2.0 Preamplifier

Agreed. Most everyone knows that although Siemens made the E88cc and cca identically, the cca were specially selected for the post office back then.

Hi guys,
Mark here,visit the Canadian equivalent of audiogon.www.canuckaudio.com.Last week there was a trio of CCa's for $225.Also,ECC88 gold pins and Amperex come up from time to time.If you see something you like let me know and I'll ship them to you from my MI address.

now that ive tried the above tubes and volvo/amperex e188cc along with my 64 ccas and others no doubt they all have there own character and sound. the ccas are more thin sounding compared to the e188s while the amperex have better bass and mids IMO. in the end i believe until you audition a verity of tubes in AHs preamps you may be missing sound that appeals to you better. like finger prints and ears we are all different and what sounds better to me may sound like crap to you. i'm sure most of you have taken the time to experiment on your own and already know its worth the trouble and expense for better sound.

You are right on about experimenting with different tubes in the AH preamp. I just bought a pair of older(1958) Amperex e88cc I am going to experiment with. I found that so far my preamp sounds best with a pair of early 60's Siemens Cca in locations 1 and 3 with a pair of early 70's Siemens A-frame e88cc in 2 and 4. All Cca seemed to be too smooth, lacking in spatiality and air. The AH preamp also responds to power cords. No matter what power cord I try on the preamp, I can hear the difference, for better or for worse. Also, Victor just informed me in an e-mail that Joseph will be announcing this next year a new tweak for all his preamps. Stay tuned for an announcement soon from one of his Beta-testers. I don't know the details of this new tweak.
