Reach out to VTV, because I'm not experiencing any of the issues that you've experienced (e.g. standby distortion, power switch pop.) I've turned mine off & on several times before doing a little re-arranging of cables and haven't heard anything.So far really happy with the VTV, it sounds exactly like the PA5 & Outlaw 2160 (thou without any AB hissing) which is to say neutral without any coloration of the original signal. The only issue is when turning on/off via the rocker switch* I get a slight click sound thru the speakers even with no input devices connected.
It's not a loud sound and it happens immediately after the relay click sound coming directly from the amp (or practically simultaneously). I have no concerns about speaker damage but none of my other amps (PA5, Outlaw, ATI, Monoprice, Denon) make any on/off sound thru the speakers.
Is anyone else experiencing this?
*no longer use the standby sw because the front panel lite was always on and now using the rocker sw - lite-on/amp-on; lite-off/amp-off.
Did you post your inquiry on any of the DIY Eval-1 build threads here to see if anyone else has experienced this and if they were able to rectify?
