Audio Horizons TP 2.0 Preamplifier

Markwatkiss,

Thanks for the update. Meanwhile, I continue to listen to iterations of Joseph's SET power amp - and they continue to improve. I understand that within the next few weeks I will listen to a SET power amp with a different tube complement and more power. I'm looking forward to the audition even though I haven't felt any loss of SPL from the lower watt SET.

As Nelson Pass has memorialized in his "First Watt" amplifier series, almost all of what we will ever want to hear is delivered in the first few watts.

Hey Mark! I'm glad to see that you found a deal on an upgraded 2.0 model. Enjoy the music. By the way. Has anyone spoken with Victor lately? He was to post upgrade and update information a while back and he has disappeared from this thread. I hope he's all right.

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
