Audio Horizons TP 2.0 Preamplifier

Just received my unit this afternoon and set it up. Had a hum using RCA output with none using balanced outputs, called and Victor and Joseph responded immediately with recommended fix to close the ground. I will listen for first time this evening when family goes to bed.

Ralph, I'm not sure what you are talking about regarding the chassis ground. I am plugged directly into the wall outlet and my preamp is dead quiet. Do you still have a hum problem?
Joe, glad to see that you have received your preamp. I am anxious to hear your evaluation. The preamp will take a couple of days, however, to break in to achieve its smooth character. I definitely recommend the best power cord for it. Interesting that you got a hum on RCA. I only have the single RCA outputs and never had a hum. Must be a system dependency issue.

Sherod, I do not have a hum any longer after looping a ground. The chassis ground i am talking about is marked on the rear panel next to Balanced in. When looking at picture posted by the advertisers Joseph and Victor you will notice some sort of POC.

RalphCast - I too have a empty hole marked chasis ground. I can only assume it is for later when Joseph has developed his phone stage which is in the works. But if you find out let us know
Joe

Hey Joe and Ralph! Any preliminary thoughts on how your new preamps sound?
