Audio Horizons TP 2.0 Preamplifier

Joe, just a brief while back I was very "green" about tubes. I learned quite a bit about them in general from reading through the Tube Asylum on the Audio Asylum website. I still go through some of these threads from time to time to refresh my memory. One of the things I found out about tubes is that the best ones, which are usually NOS( but not all) are like a seasoning to the circuitry. It's amazing how so many audiophiles have so many different preferences in sound. Bottom line is what sounds best to you. There is no one best particular tube. IMHO

Yes, I have looked through the tubes threads at Asylum and found them helpful. Victor is very sincere in his conviction that the cc'a's and, short of that, the gray plate Siemens are best in the TP 2.0. And he is very knowledgable and dedicted to the search for "absolute sound" and an expert in the TP 2.0. Yet, from what I hear that the Amperexs can give, they sound intriguing as well. Beside musical perferences (I want to tune my system to awesome classical, though I listen to other genres as well), equipment, and room synergy, you have the personal taste mentioned. Given all this there is plenty of room to experiment. To paraphrase "so many tubes, so little time".

Gentlemen,

Thought I should mention that the preamp is outstanding! I have about 35 hours playing time and wanted to thank all on the board for sharing their impressions about this wonderful preamp.

I wanted to contribute this information to those who are looking in and for us "Component USA Clubers". I was about to purchase Amperex tubes to replace the Siemens since I found them to be on the thin side. If your taste is akin to this then keep trucking with the Siemens. I am no longer searching for any tubes after I did a semi-cryo treatment on the TP 2.0. The sound is on another level toward 'organic' with tons of flavor in the midrange and a beautiful soundstage that ooozes 'synergy'.

In my opinion the freeze treatment enhanced the break in period of this player and it will be interesting to see what additional improvements is on the Horizon LOL!

Lou,
Can you explain what a semi-cryo'd treatment is?
