Bass leaves after amp warms up?

Open letter to Dan @ Modwright
Hello Dan:
Thanks to Kristin as well
I have a long standing problem where bass is anemic sounding along with the rest of dynamics.
All of a sudden the bass comes through like a flood and the system sounds great.But it comes and goes throughout the day.
I have no explination & have changed eqiupment all year with the same result
Question
My speakers are 4 ohm and there is some debate on audiogon that these are difficult to drive.
Is that why your integrated amp doubles into 4 ohms
I currently have in my audio setup:
PSB Synchrony one speakers
Meridian 508.24 cd player
Rega P5 Turntable w/dynavector cart
Musical Fidelity M6i integrated amp 200 watts w/Kimber PK10 pc
DVD,TV w/cablew/
Audioquest comet speaker cables,biwire
Audioquest columbia interconnects RCA
Cablepro Revelation Power strip w/kimber PK14 pc

We designed the amp to double-down into 4 ohms because we wanted it to have TRUE power, capable of driving MOST ANY speaker. I wanted a beautiful looking and sounding integrated with POWER and available dig. and analog options to make a no-compromise integrated solution.
Thanks and in look forward to your reply.
Sincerely,
Dan W.

maybe it just leaves your amp to go to the nearest neighboring amp?

I saw that you had listed your system for sale. Did you get to the bottom of the problem or have you just given up?

Fishing716... understandably you're selling the amp, but why the Synch One's?
