Re: Onkyo M-504 Amplifier (SS)

Perhaps into the low impedance load of the Apogees the power supply sagged, causing high frequency roll off ?

I have some Klipsch CF 4 speakers, a 4 ohm load.
With a small Parasound HCA 500, a 50 WPC amp, they sound "mellow".

Yet, the Parasound is not really a mellow amp on my 801's.

What is happening on the Klipsch CF 4's is power supply sag, hence a dull sound, until clipping.

The Onkyo 504 even made Vandersteens sound etched, not an easy thing to do!

Did you try the 504 on anything but the Apogees ?

I have had several Krell amps, and I found many to be rather bright, but all had tremendous bass.

I think the old Krell KSA 50 was the best sounding Krell amp I ever owned.

I had a KSA 200, it was almost unlistenable on the 801's, not hard sounding, just super bright, to the point of being unmusical.

I sold it to a guy using it with old Magneapn MG 2's, and he is in heaven!

He has had the Krell for 5 years, and loves it.

He lives up in Vermont, I live in Florida.

The big Krell made the room to hot, and dried my skin out, LOL
