Audio Horizons TP 2.0 Preamplifier

Sherod, Thanks for the reply and suggestion.

You're welcome, Ozzy. Once you get back home for some serious listening evaluations, I look forward to your impressions.

I brought Ozzy's perception that there "does seem to be a shift in center stage to the right of center" to Joseph's attention, since we are always attentive to ways to improve the preamp.

Here is Joseph's response, edited just a little: "The gain deviation between channels is 0.2 dB; the tracking error from the volume pot is -1 dB or better when the volume pot is set at -60dB position. This could be an issue for the n version since it has higher gain than nB if the system has highly sensitive loudspeakers. It will be hard to find tighter tolerance available from the supplier of the motorized pot; it will be much easier to get regular pot in tighter tolerance."

I take this to mean that while the the output deviation is small, at some points on the pot at certain gains, with certain highly sensitive speakers, a 1 dB deviation between channels could occur. Sometimes other factors unrelated to the preamp can also contribute a small amount to the perceived deviation.

I take it, without his needing to comment, that Joseph will look for a tighter tolerance pot.

Thank you for bringing this to our attention.

Victor, I am a bit confused. Does this issue only apply to motorized volume controls, meaning the remote controlled units? Also it would seem that dead center image is pretty sensitive. I can move my head a few inches left or right and slightly change the apparent centrality of the sound in my system.

Victor,
Gammajo took the words right out of my mouth.
