Peculiar problem? Show me the light...


OK, I'm going to try and explain this as best as I can. I don't usually listen at mega volumes so this has not been noticed before. My Revel M20s can handle just about anything I put through them, and my subwoofer picks up the base inadequacies. There are some pieces of music that have tremendous base punch, and at very loud volumes I hear my Revels cracking up. Not my sub, but the M20s. Both speakers. If I turn down the volume gain from the neutral setting, on my subwoofer, the crackling goes away in the M20s. It's wierd. If I play the same piece of music with the sub off, I can play at prodigious volumes with no crackling at all. How can my self-powered sub, effect what's coming out of my speakers. I have it hooked up via the preout from my integrated. The sound, otherwise, is wonderful, but at the loudest levels with some powerful transient response type stuff, it'll crackle. I hope I'm explaining this properly. This is a very livable situation, for I just, in a blue moon, crank it up to satiate a sonic desire, sometimes. And it doesn't happen with most music. Anybody have any ideas? You might need more information, so hit me. Thanks in advance my audiophool friends. warren

It makes perfect sense about power starvation pertaining to the dedicated verses shared lines.

Warrenh, like sidssp stated, you should notice at least some improvement in macro-dynamics or dynamic headroom when you take the sub off that line and put it on another. Even though you could hear the ill-affects at louder volumes due to absolute starvation, you are still potentially starving your amp even at lower volumes. Just not to the same degree but the difference is still usually audible.

It's amazing what sonic improvements one can experience by installing dedicated lines and it's the cheapest of upgrades. Anything containing an amplifier should idealistically have it's own dedicated 20 amp line and circuit and all other components should have 15 amp dedicated lines. And it's equally beneficial when one installs another dedicated line just for digital and yet another just for the pre.

And once you have dedicated lines installed, you will still benefit more when you install good quality power conditioners on those dedicated lines.

Warren, thanks for the email. Swampwalker is most likely correct about the Stealth being limited on the current draw.

You might try using only the integrated on the Stealth, your source on the other outlet, and your sub on the extension cord again or even try moving the three around to see what improvements you may or may not hear.
