Audio Horizons TP 2.0 Preamplifier

I would like Victor or someone to help us understand what they have found for burn-in time and changes one can expect over that time.

Sherod, I find I am in agreement with your overall comments on the improvements and also what seems to be missing. More burn in gave me back more of the roundness and warmth to the music. However changing the cabling before the pre really made everything come together. I use the same cabling Joseph does - at least I think I do. I use 100% AH Transparency cabling throughout my system including power cords. I think AH uses the same and voices the preamp based on this wire.

These cords have more body and fullness then many others I have owned. The Music Metre Fidelus digital cable I used to use had more detail and a front row seating position. It worked very well with older 2.0 version. However, the more laid back and full sounding AH now works much better in my system. I have all of the fullness and life I used to have plus now I also enjoy the improvements you noted.

Seems to me the updated preamp has changed pretty dramatically and what used to work for cabling in one's system now may not. I know this will mean more time and effort for ideal system matching for some - yikes!!

I am pretty confident my comments are on point and would love to hear comments from Victor or Joseph.

I might have been premature in posting an impression. I just received an e-mail from Victor and since Joseph does extensive mods to the power supply along with the new wiring harness and output caps, Victor told me to hold off for at least 100 hours to make an impression. It just passed the 54 hour mark, so there is a ways to go. I'll be patient and give it more time.

If 100 hours is required for break-in, then Audio Horizons might re-visit their 10 day Audiogon audition policy. 10 days is not nearly enough time to allow for 100 hours of break-in.

Perhaps the payment-free, Audiogon audition period should be extended...or perhaps AH should send dedicated audition units that have already been through the break-in process.

Just a thought.

Tvad my audition 2.1 had 50hrs on it according to Victor. There operation is so customer friendly that its a super pleasure to deal with Joseph and Victor at Audio Horizons.

Good idea, Tvad. Maybe Victor will address this in their website or on this thread soon. I had thought that the trial period was 30 days. Maybe that applies to their cables. Victor, it might be time to clarify some issues to eliminate the vagueness of some things.
