Bat VK-P10 and Sonic Frontiers SFP 1 Signature

The problem existed with both a Clearaudio and a Koetsu. In actuality it also exhibited a ground hum with the Clearaudio that only was there in the balanced mode. I switched back to an RCA phono cable and solved that problem. BAT acknowledged the issue with Clearaudio cartridges and earlier VKK-P10 that did not have truely balanced inputs. They did not offer to remedy the problem. The noise I am now referring to is an amplifiable hiss that is more of a problem with both jazz and classsical music. The preamp has been moved to isolated locations that would preclude other equipment from being the cause. As stated, the Sonic Frontiers Signature costing one third the price and also a tube preamp is much quieter.

jfrech, I beg to differ with you, but I brought the VK-P10 into True Sound Audio and Nick spoke with Victor and someone else at BAT and both indicated that the input circuitry eas modified on later VK-P10s to make the inputs truely balanced,

The unit was shipped back to BAT and found to have a defective regulator. i was told that this would definetly cause the preamp to be noisy. It's on its way back and I'll report on the results. By the way, they fixed the unit at no charge to me.
