Does anyone play two pairs of speakers at the same time?

I run a pair of AR3's horizontally stacked with a pair of AR3a's. The 3's are driving by a McIntosh MC2300, the 3a's a Mc MC2105. Both amps are fed into a Mc C22(original, not reissue) preamp(with Y IC's), and the preamp is connected to a McIntosh CR7 remote which is how the overall system volume is controlled. Doing this because I have the gear lying around and no place to set up a second system, but more to the point it sounds better. A lot better. In every way. And yes, it sounds excellent using just one amp to drive either pair of speakers. I pay little attention to so called experts on stuff like this because at 64, having been involved in audio since I was 15, and listening to and owning all kinds of gear, I trust my ears with harmless stuff like this. Works for me.

Like the hippies used to say, "if it feels good do it."  Note: that doesn't apply to scratching mosquito bites.  But as for me I prefer a single pair of the best speakers I can build.

If I was down to one pair of speakers I'd do the same. But I have multiple speakers and multiple amps that I love, and only room for one system at this time. I'd rather use them then let them just sit in a closet. I'd sell them  but nobody is buying these days. At least for not what I'm asking, so I use them instead.

 

There have been many technical discussions on the "multi channel stereo" setting available in receivers and pre-pros. In essence, this is the same stereo signal sent to your 5.2 or 7.2 surround setup. It is misunderstood as party mode for non-audiophiles. But, it is not if you tweak it right. I have used that mode with great results in the past (timbre matched speakers and placement tweaks).. But, with immersive Atmos/DTS X upmixers or native available now, i don't do multichannel stereo that much anymore.
