Audio Horizons TP 2.0 Preamplifier

stltrains, thank you for the suggestions. Unfortunately,
I only use CD/SACD as a source.

Luxman has a new preamp with tone controls also.

As we all know audiophiles look down on tone controls but will spend $100's and even $1000's on cables to do the same thing. I for one would welcome tone controls if it could be done without degrading the signal, perhaps as you suggested by switching it out.

Frank, thanks.

One of our customers was so impressed with the Transparency AC Power Cord he sold all his high end cords, and while at it suggested that Joseph design and market a power conditioner. Frankly we had never even considered it. I would appreciate hearing your thoughts on his suggestion.

Personally I think that the market is already over-saturated with AC power conditioners. Unless Joseph can introduce something very cost-effective and revolutionary, I think he'd be better off focussing on his previous plans of introducing a unique power amplifier. Also, Victor, how are the plans going for an upgraded SOTA preamp which you mentioned in a previous thread?
