Hi, sorry to hear about your continued problems. I've owned the PSE preamp and had no problems with it at all. You have a great system. I've heard almost identical ones and I understand why you keep it despite your problems. So, _IF_ you decide to replace your preamp and amps here is what I suggest. Get an Aesthetix Calypso line stage and a single BEL 1001 Mk V. You will get a great sonic upgrade along with very reliable components.
I hope that helps!
