Bass leaves after amp warms up?

Lowrider and Al, my sense is that a Bryston separate amp would muscle its way through any power delivery barriers (short of a short) -- if that's the problem. Btw, admittedly, my Paradigms are about 3 db more sensitive than the PSBs. Even still, it's been my experience that my ARC VS-115 has had no problem with power delivery. Indeed, SPLs are painful if I turn the gain up on my line stage more than 50 percent.

Further, if you read some of my other posts in other OPs, you will see that I have neurotrically obsessed about my speaker's wacko impedance and phase angle numbers. At Al's and Ralph's recommendfation, after intense consultations with an audio-shrink, I am now convinced that somehow my poor little VS-115 (120 wpc) has deftly powered my "tube unfriendly" speakers very nicely.

Al, I re-reviewed the impedance and phase angle graphs. The measurements from JA and SoundStage are quite different. BUT I think both bench measurements still raise the same issue -- can Fish ...'s integrated deliver power into those impedance numbers without getting indigestion??

So ... the bottom line is IF (???) Fish..'s integrated is having indigestion driving the PSBs because of the low impedance levels, the Zeros may effectively double what the amp sees. As alluded to above, even if the amp's power output is cut to 100 wpc, I think Fish...'s ears will hurt if he pushes the gain up.

Incidentally, if Fish...'s amp is rated at 200 wpc at 8 ohms, presumably doubling the PSB's 4 ohm nominal impedance number should not significantly affect the amp's power delivery capability.

So Mr. Fish...., as Al or Ralph said above, if every possible logical theory except for one illogical theory has been ruled out, then the remaining goofy theory must, no matter how improbable, be the answer. I suggest you call the Zero guy, tell him your problem and confirm if he'll take the Zerosm back if they don't work. Otherwise, go invest in a monster Bryston or get new speakers. IF you're really satisfied that everything else really is A-OK, then this is the only possible answer.

IMHO of course.

P.S. -- of course try Ralph's suggestion about unplugging the digital. But I thought everything else has been ruled out. ???? :>(

Today I will set up just amp & turntable sans digital.
Sounds like a good experiment!

Sounds like a great experiment. I would also use the power cord that came with the amp instead of the Kimber PK10 you have been using, and everything plugged to the wall outlet. Keeping the system as simple as possible will help to resolve the problem.

"Yes the optimal sound has left then returned an hour or day later but I usually fiddle the cables long before that happens."

Its possible that if the amp is on but not playing music that it might return to a more normal state when played again. What would work against the amp can't handle the load theory is if the sound ever improves after the suckout occurs while the music is still playing and without changing anything, not after sitting idle for some period of time.

I disconnected all the digital & power conditioner.
All I'm running is the turntable plugged into the wall.
Today was probably the worst sound in a long time
I seem to be going in the wrong direction
I was unable to establish the solid bottem end at all.
The sound was restrained & boreing/lack of dynamics.
I switched speaker cables many times with no eureka moment.

My conclusion is I am in someway inept at the task at hand and require an expert.

I get deep bass sometimes which I enjoy and I get passive bass most other times.
Perhaps the power conditioner is bumping up the bass sometimes like a subwoofer & then settles down to less dynamic sound?

The other day I borrowed Analysis Silver speaker cables from the cable company and hooked them up.
There was alot of indistinguishable "noise" in the bass region but it was undefined & I didn't like it at all.
Perhaps the Audioquest comet has some way of "doubling" the bass in the first hr.
Again I need someone with knowledge of what sounds right to assist me.

The bass when it is there clearly is is taut yet supple,moves air & can eaisly follow the bass line..Adding much emotion & excitment..
I get that with all sources or not with any sources..
I'm more than beginning to suspect a curious "malfunction" in my processes if not hearing/interpertation.
I don't even think Freud would take this case..
