Bass leaves after amp warms up?

Ok Fish..., here's what I got off the web.

HT Lab Test (12/07): The Synchrony One's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.18/–2.24 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 56 Hz, and the –6-dB point is at 50 Hz. Impedance reaches a minimum of 3.32 ohms at 70 Hz and a phase angle of –37.55 degrees at 27 Hz.

SoundStage (1/08):

The impedance magnitude and phase angle graphs are absolutely amazing!! I've never seen flatter. Problem is impedance over large swathes of frequencies is unbelievably low, especially in the bass frequencies.

Al and Ralph -- take a look at the graphs at the URL above. I'd like to read your thoughts about whether a solid state amp, or any amp for that matter, would get indigestion from those impedances. Fish ..., if Al and Ralph come back expressing concern, the Zeros are seriously looking like the solution.

Fishing, here is an article about the other conditioner that was referenced in the AudioPrism review. It’s long, but read carefully @ Listening Up… the Game is Afoot. The last 3 sentences of the 1st paragraph seem to somewhat describe your problem. The next paragraph talks about positioning the conditioner, and further down shows a picture of a fairly extensive setup.

I may be ”grasping at straws”, but just trying to help. The best way to determine if the AudioPrism is causing a problem is to take it out completely. Just use something like a heavy duty outlet strip to get enough plugs for everything, and you probably will notice some degradation of sound, but play the system to see if the problem occurs. If it does, we’ll just keep looking for other ideas. At least, this is something simple to do, and I don't think it is something you have tried.

I've tried power strip recommended by Naim/one by emotiva/wall outlet & Audio prism.
The best sound was with the Foundation II.
Bass issues were never stabilized by anyone of them.

that was very informative article

I often feel my turntable seems to sound better/longer than my cd player lasts.
And the Video dosen't last long at all
That's why I've been playing records alot lately.
Analog can't be beat anyway..

The best CD players I've had were
Linn ikemi,Bryston BCD-1 & Sony SCD-1
Ayre wasn't my cup of tea for some reason..
Currently autitioning Naim CD5 XS but after one cd the sound changes for the worse.I prefer not to misjudge this player when the full frequency's are messed up.
This probably happened while auditioning Ayre CX7 eMP.

Source components with relatively low voltage power supplies (usually 25 volts or less) will tend to have broader current pulses with lower peaks. Larger components with higher voltage power supplies, like amplifiers, will have current pulses that are shorter in duration, and higher in magnitude (amps). This is because amplifiers have to get all their power during the small portion of the AC waveform that is higher in voltage than the power supply in the amplifier. The current pulses vary in frequency and peak depending on the frequencies and volume level of the music being played. These current demands may well be the reason that it is not too unusual for mid-priced PLCs ($300 - $600) to sound like they are limiting amplifier performance instead of making them sound better. Mike VansEvers is designing his PLCs to cope with those short duration, high current demands from audio components.

What does "the zeros" are looking like the solution mean?
