MC402 vs FPB 300cx

Great advice Audphile1...You really know your stuff. thx!

I have Nordost Tyr from source to pre, and pre to amp. Then Kimber 8tc for speakers. My dealer has already suggested it being the speaker cables and he is going to send me a set of Auditorium 23's to audition once they come back from a current audition. If sp cables solved glare I would be shocked, not that I am doubting, I would just be very impressed by that cable.

The amp is on standby at the moment, so it warms fairly quickly, but I think it sat ALOT and did nothing, so your points are good ones. And yes the amp is ridiculously resolving.

Another theory on this glare I am experiencing is the listening room...I have increased the soundstage of the speaker considerably blah, blah, blah. Maybe getting glare of the walls etc I was not getting before because the sound is greater. Crazy?

Jc51373, better cables will certainly help.
I think now, with this amplifier, you should be able to tell difference between cables pretty easily.
You said you think that your speakers are the weakest link. I think your speaker cables are the weakest link at this point. They barely fit with the rest of your system now that you have taken it to the next level.

If you don't want to spend a lot on speaker cables, try a used pair of Acoustic Zen Satori Shotgun. They should be a very nice step up. I had these and they worked pretty good with my B&Ws.

I think you might be right, and if nothing else it's the path of least resistance first. I am actually anxious to try the Auditorium 23's as they are supposed to great for the money. I guess you could say 8tc is not quite up to the task of this system now, I was just hoping not to get sucked into the expensive speaker cable trap again. But heck, if it works I am game.

I gotta tell you though, the detail and smoothness, accuracy, and speed, bass response, silence, and soundstage is everything I expected in this amp. In that respect I love it. In fact the soundstage changed enough that I had to re-toe my speakers to compensate. But...I won't completely head over heels in love with this new Krell like I was my old Krell until I resolve the glare.

My ultimate fear is that this Krell is not for me, and have to go with another amp. That would be a chore and half.

How do you like your Pass? Nice choice.

Krell is recommending capacitively coupling the amp to resolve the glare issue-FPB is direct coupled of course. Something they recommend to do with Tube Preamps regardless, which I have. The KAV I owned before this FPB comes from the factory capacitively coupled. I personally think this is not the answer in trying to resolve sibilance, but the only thing that is compelling me to do it is the fact my KAV sounded great. Alot sweeter. If adding a capacitor into the signal path will change sibilance I will do it, but given the fact there already about 500 Caps already in the path, I have my doubts that adding one more will do much in softening glare.

Working in steps, taking deep breaths trying to be patient as I go..Otherwise, this thing is a boat anchor. : )
