Audio Horizons TP 2.0 Preamplifier

Maybe this thread will surpass the Supratek thread in posts and longevity.

FYI, the magic of Joseph's preamp really didn't click in until I replaced tubes location one and three with 1960 Siemens grey plate CCa tubes. These particular tubes are rare and very expensive, but I heard a significant difference after trying various other Siemens CCa and E88cc versions. Various Amperex, Valvo,etc. versions need not apply. I think that Siemens borrowed a few Elves from Mullard to make this particular version CCa because the music it makes is truly "magical". IMHO and YMMV.

Hi All, I have have been keeping up with this site. I was on the fence with many Preamps (Tube), ended up with TP 2.0nB had issue with slight hum, but Joseph was on top of it all the way, I even received a call from him on Sunday to my surprise! The hum is temporarily taken care of soon to be a permanent fix. I will post my final audition thoughts after proper burn-in time so far very happy with sound!!!

Markwatkiss - Thanks for the welcoming message. I feel privileged to be in such descerning, gracious and helpful company!
Ralphcast - I'm jealous still have to wait till the end of the week to receive mine. Welcome aboard and we are eager to hear your reactions.

Question for those proud owners of TP 2.0, mine came without any type of chassis ground setup, just a pre-fab whole. Wondering if was the same for anyone else.
