Audio Horizons TP 2.0 Preamplifier

Ahh, the joy and expense of tube rolling...

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?

Here's an interesting thread I started recently in another forum regarding the Siemens CCa tubes:

Sherod,

What I meant by semi cryo is freezing at zero degrees. If you were to do the full cryo its faster and the temperature is much lower in an controlled environment.
