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

@canibefrank,
Of course you can be Frank. "Consider for a moment any beauty in the name Ralph."

I too am looking for a preamp. Yes the Freya has got some good recommendations here and elsewhere. But, I really want tone controls, and the soundstage control and extra outputs on the F360 are interesting. There's just not a lot of info or reviews out yet. I can't even find the manual.

 I would take Schiit over anything out of China.
Check the UnderwoodHiFi Black Friday deals for the Black Ice. 

@canibefrank,

Black Ice F360 - Here's a link with some show videos and some pages from the manual on the SSX, EQ, and rear speaker functions.

I wonder how many people think experimenting with speaker placement and volume matched multiple speakers is a bad idea have ever actually tried it? As I said previously been messing around for years and there are some truly great combos. (Yes I have SPL meters one pro and one old Radio Shack also can switch from my chair up to 7 pairs of speakers and any combination of pairs including running all seven pairs.) Have fun everyone, enjoy the music and gear in the new year!

It was many years ago that I happened to own 3 sets of speakers for my system. The main pair were JBL 4343. But then, I got talked into buying a small set of Maggies. Thirdly, a set of Klipsch Cornwalls were added. First off, the JBL and Maggies were very tricky to get right. When I did feel satisfied, that would all change in the next album or so. To try and match the Cornwalls to ANYTHING was a total waste of time.
 Headphones placed partially on the head with speakers running rarely works unless the speakers are facing each other like a giant set of headphones next to your head. I don't experiment as wildly as I did in my 20's or 30's, but don't belittle anyone wants to give experimentation a try. Overall, I have enjoyed the hell out of this hobby, straight or with a twist.

I moved a pair of Zu Omen MKII rev A speakers I'd been using in a second system  with an Elekit TU 8233 I assembled (2a3) into my primary system MAC7200 and Graham LS5/9 (on selectable pre out -2). The Zus are set up slightly in front and outside the Grahams forming an equilateral triangle with a bit more toe in.  Id intended to use the Grahams for jazz, classical, acoustic and the Zus for rock.  Independently they imaged very well with a good soundstage, tone etc- It would be difficult to tell which speaker is "on" for someone not familiar with the sound of either speaker.  Last night I had both on and was amazed at how musical they were together.  Its like their shortcomings were minimized and there is a real synergy.  it seemed to bring greater focus, more dynamics and presence and more solid foundation and a better tonal balance with both on than either by themselves.  I a/b'd and a+b over and over with different tracks of all genres from Bill Evans ti Metallica and found the sum more enjoyable than the parts.  From what I'd read before this wasn't supposed to be the case so I searched and found this thread.  Thought Id post this experience for what its worth.
