I looked up your amp (nice amp, good pick) and see it doubles at 4 ohms so dropping impedance shouldn’t be a problem, but the 2 massive torroidal power supplies may be strangling your power grid - no power conditioner for the amp, correct?
Hi Jay - the dropouts (confirmed again last night after shuffling interconnects) are mainly during relatively quiet parts - e.g., dialogue during movies, etc. With action scenes or playing music (i.e. under higher load), not as much.

BT - I also swapped to the Active outputs on the pre-amp - no change in behavior.

FWIW, I do have a power conditioner (API Power Wedge - another 20 YO vintage).

I will sound like a broken record - check out Brett's used / vintage gear at Hifi Heaven and Command Performance AV both located in Falls Church.

Thanks to Jay for the loan of a couple pieces of equipment. It's the power amplifier.

Off to shop for some new kit.

Ended picking up a PS Audio Stellar S300 power amp. This is a hybrid - class D with a MOSFET class A input stage, built on a pair of ICEpower modules which can drive 300 WPC into 4 ohms.

The low pass filter for the class D section rolls off at 50kHz.

VERY impressed so far - very listenable right out of the box with great detail and sound staging.

Unless something goes drastically wrong I’m probably hanging on to it.
