Bass leaves after amp warms up?

Could it be that the bass is tightening up as the amp(s) warm up and stabilize? Is it going from bloated to more lean with better definition?

There's 148 posts to this thread and I haven't read them all but I know that's it's been brought up. I just don't know what your response was.

Why don't you at least try a power regenerator like a PS Audio unit to rule out any chance that it's a power problem from high usage? That way you know that your power to all of your components is consistent.

After 300 posts and all of the logical advice that's been given, I don't think that you're accepting the three apparent possible reasons for your dissatisfaction.

1. Power - you say that an electrician says that your home's wiring is fine. That's not what we're saying. The power draw on your grid has nothing to do with the wiring in your home.

2. Acoustical treatments and speaker position - maybe you need to seriously look into your room and system's setup.

3. Disappearing bass - if you left your components on all of the time you would actually hear what they sound like as the manufacturer intended. If you like the sound when the system is cold but not warmed up, and it's not the power draw, the room's acoustics or the speaker placement, maybe you just don't like the sound of your system and need to change components.

It seems like you have your mind set on one sight, and are not being open to an answer and solution that you don't want to hear or want it to be.

Rrog,

That's what it really sounds like to me too.

I had a Musical Fidelity A308cr power amp for a few years and it was excellent. If the M6 is anything like the A308cr, I don't think that's the problem.

If it is, this is the Class D amp that I use and it will take a hold of your speakers and tell them what to do: http://app.audiogon.com/listings/solid-state-spectron-audio-musician-iii-mk2-w-free-v-cap-upgarde-new-sealed-2013-04-03-amplifiers-91325 Tell them that you want it without the V-Cap upgrade and see if you can't get it $3,500.00.

You may want to borrow someone's CD player that is better than yours and see if that's not a problem. If it is, relax and wait until you can afford a better one.

Csontos and Ralph,

So, if I'm understanding what you're saying, some amps sound better cold than when they're warmed up? If that is the case, anyway it goes, it seems that a person needs to leave the amp on and accept the way it sounds warm.

That is, unless you want to listen for an hour, turn it off, let it get cold again and then turn it back on and listen for another hour. That just doesn't seem to be an ideal way to listen to your system.

If a warm amp is at least consistent even if it doesn't sound as good, at least you have a known sound that you can count on.

Am I thinking wrong?
