Audio Horizons TP 2.0 Preamplifier

Anyone famaliar with the manufacturer,and in particular
this pre amp.The credentials and testimonials seem
impressive.The advertised 10 day audition is appealing.
I just wanted to say Hi to all the AH family outhere. Glad
to see this thread is alive again. FYI, I'm still quite happy with my AH 2.1nB preamp. Like others I am very curious in regards to the upcoming updgrade.
Thanks for the preliminary information on Joseph's new SET amp. Could you give us some information on your Beta testing of the TP 2.0/2.1 with new upgrades? I have had these new Claritycap MR caps in my TP 2.0n preamp for about 100 hours. At this point, I don't want to take them out yet. Joseph is going to order a pair and experiment with them when he returns from Thailand in early April. I'm happy to hear from all the AH preamp family. It has been a while since I've heard from current or past users. Please keep this thread alive and post from time to time.
Joseph brought the test unit over to my home twice to listen to it in my system. So, I've had the pleasure of listening to the new preamp upgrade in my system for about two hours. That was enough to persuade me to order the the upgrade.

Before I say more about the improved soundstage, lower noise, greater detail and more natural sound - which I heard in these listening sessions - I will wait to receive the upgrade into my own system.
Just to be clear.When you say upgrade,are you referring to modifications for a 2.0/2.1 or an entirely new pre amp.
As you know, Joseph tries to offer upgrade paths. So, with respect to my system, I will receive upgrades to my existing 2.0nB (which has been modified previously from the original configuration).

Several weeks have passed since I listened to the preamplifier modification. I recall that the modifications to which I listened were test bedded in a 2.1 chassis. I don't recall the list of all changes made, but there were substantial changes made. These changes that I saw may be enough to justify a new model designation (changes such as new transformer). That may be the path Joseph takes. Victor would be a reliable source of that information.
