Why Don't We See More High Current Electronics?

Although I always have the greatest respect for opinions expressed by Ralph (Atmasphere) and Grant (Tvad), and I almost always find myself in agreement with both of them, in this case I think that their posts are commingling two separate issues.

ANY amp having negligibly small output impedance, such as most solid state amps, WILL double the amount of power that is delivered into a halved load impedance, PROVIDED that it is operated within the limits of its maximum voltage, current, power, and thermal capabilities. That is a matter of basic electrical engineering principles. If in fact Harley disagrees with that he is wrong.

Most, and perhaps nearly all, tube amps will not do that, BECAUSE their output impedance is not negligibly small.

All of that is essentially a separate issue from the one I believe Emerson (Foster_9) was asking about, which I believe concerns whether or not the MAXIMUM power ratings of a solid state amp are twice as much for a 4 ohm load as compared to an 8 ohm load.

...there may be other reason's it doesn't sound bright other than just the double down aspect.

I suspect this is correct.

Okey-dokey. I'm bowing out.

Al, I always welcome your posts. The "PROVIDED" you provided is the operative word.

Hack, remember that a high current amp will decrease power into higher loads. There are limitations in either case. Choose your speakers and amplify them appropriately.

Foster,

Sorry to hear your still fighting bass and other issues. Your case is a tough one to get a handle on because I know you've tried so many things, including subs, and still have not yet scored completely.

Even if everything is matched well electronically, room acoustics and individual preferences still come into play in determining what sounds good.

Maybe a near field setup of some sort might be the best approach if you can get to that kind of setup in your room.

My best guess is the thing you need new most is a new room. Unfortunately, that is one of the hardest things to have to deal with.

My wife's very lively sun room, 12X12 with a cathedral ceiling, lots of windows and a hard tile floor is that way. What sounds spot on other rooms never quite gels completely in there. Generally there is too much bass and imaging and soundstage is not totally up to snuff. Fortunately for me that is only an auxiliary listening location so I am able to live with what I get there, though I have not given up on trying to get it perfect.
