Is there any obvious advantage for monoblocks?

I own a Parasound HCA-3500.Hard to move around, but exceptional bass power and extension, goes to REALLY HIGH VOLUMES without compression or strain, and has great imaging and sounstaging.The bass is its biggest advantage in my situation.I use 2 dedicated 20 amp breakers and 2 seperate lines and outlets for each power cord!!

Don't underestimate shorter speaker cables and, in my case, extreme WAF! I was able to hang each mono off a basement joist just under each speaker, threading 8 foot cables up through the baseboards to each speaker. Look, Ellen, no Alephs! They run cooler down there (as well convecting better as there's no "floor" in the plastic milk crate each sits in, and the longish XLRs from upstairs are completely quiet. Using a mid-mounted stereo amp would have eliminated the laundry room, and y'know, ya gotta have clean clothes....

Subaruguru...We agree! (Something must be wrong here). All my power amps and electronic crossovers live in the cellar, and have done so for decades. Besides, that way you can hide from your audiophile buddies the fact that your amps don't carry high end nameplates.

Here's a twist: Is there an advantage of replacing your stereo amp with two monos rated at lower power? For example, let's say you went from push-pull KT-88 stereo amp and went to a pair of 300B SET amps rated at 8 watts per channel. Let's say that your loudspekers are pretty efficient (at least 90 db). Which set up, theoretically anyway, wins?

The Channel seperation of the SA-250 is superior to that of the SA-102 and it delivers more current, so you can enjoy both worlds: better seperation (close to what monoblocks will get you) and better soundstage.
