I'll just say you might be quite surprised at what I'm hearing now. And these prefer a 72-96 hour break-in before blossoming. I owned 2 TacT amps over 15 years ago and totally agree with your take on that amp. But then we didn't have binding posts of this quality back then either! I did investigate the PEM while inside for Kenreau who was considering a filtered F'tech IEC and also looked around to consider options I might later want to dabble in or execute. Any/all of them at first glance would appear to be warranty killers. I personally have zero use for filtered IEC's and if warranty was of no concern I'd put a F'tech FI-33R 20A IEC in there so fast heads would spin!! There's no doubt I'll do something that'll kill the warranty before it expires... ALWAYS do!! But it might be a little premature to jump out and kill it at 2 months of age! If history's any indication, prolly sooner rather than later tho.
