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.
Since acquiring my second fully modified AH pre amp I rotated out the rca interconnects,Siver Audio 4.0's and rotated in the balanced version 6.0's.Pleased with the results,lower noise floor,blacker blacks.
I'm curious as to why that is,better isolation?Comments
That is part of the design of the balanced interconnection. They call it common-mode noise rejection. It lowers noise level. It's a more expensive solution because it requires balanced mode output transformers in the preamp.

Here is a link that will offer more information
Thanks for posting on the upgrades. I am watching feedback on the upgrades very closely because my original AH is so good to my ears that I don't want to ruin it. Sounds like Joseph was able to preserve what we like about the AH and enhance beyond that substantially. I also hear that Nuforce has come up with an upgrade to their Reference V2SE that brings in the good qualities of sound found in high dollar tube amps. Which upgrade to choose amp or preamp? Any input?
