MC402 vs FPB 300cx

Hey Aduphile1...I have not had a chance to get back there yet. I gotta be honest, I am afraid if I go back and listen to the 803d's again will walk out with them and $8k worth of debt.

I am experiencing a little glare, or glassiness if you will with this amp, and I have to diagnose what that could be. My first reaction is it is the speakers' crossover spec limitations being displayed by the amp. I have to give it more time of course, but glare is something I experienced with the MAC as well, although it was more pronounced. I am hoping the problem resolves itself as I listen more and more.

No thanks to Audphile, now I can't get my mind off the 803d's. : )

Naturally this amp is more resolving than your Krell KAV was. So now you probably hear more of your other components. Not that the speakers are in fault here, but could be your upstream gear.
what are your IC and sp cables?
Also, I'd suggest leaving the amp on for few days with music playing most of the time. If you just inserted the amp into your system it could be that it hasn't fully warmed up and the caps are not fully charged yet.

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.
