In Reply to: RE: Vertical biamping , better to run bridged instead posted by A.Wayne on May 29, 2017 at 04:54:07
Again, more than one way to skin a cat. With horizontal biamping you still have the left and right channels sharing the same power supply, better separation can be achieved with vertical, just as with a mono block setup. Another advantage is speaker wires only 18" long eliminating most of the issues with cabling, again a much better more musical sound can be acheived.
As mentioned, I've tried every kind of multiple amp setups beginning with car audio back in my youth transitioning to home audio once having my home.
Active biamping can be fun, a very deep rabbit hole it is if you want to go there. But I've found keeping it simple is just that, simple, and it simply gives the most musical response to my experienced ears.

Yes many ways to skin the cat..
It is this sharing of PSU Imo is why vertical bi-amping is less of , found the same when designing car audio systems in the 70's the best was always horizontal , even then we played with vertical and horizontial bi - amping. These kind of setups were experimented with extensively , as it was during the time we were designing seperates for auto's and also to the best of knowledge the first subwoofer enclosure system for them (1976 ).
Fosgate (before rockford) Was the first with all in one bi amping setup to my knowledge , (keep three utterly unreliable) this was later exceeded by others using seperate everything including soundstream, Zapco and Audio mobile , Soundstream had decided to use Nelson Pass designed( 84) fully biased class-a amps, ( prolly the best sounding mobile amps ever.)
In our original Bi/ tri-amp setups, we used heils and a lower line used Phillips soft domes for tweeters. ( originally this setup ran (78) with Fosgates) ..
Over the years and many development stages ( Home and studio audio ) along the way we had experimented with every conceivable setup many with bespoke and off the self xovers built for bi-amping and at no time did we find vertical to be superior ..
My 2c ..
Well, I didn't really want to get into a pissing match over experience, but as early as 1972 I was cutting the leads to the tweeters in Jensen 6X9 coaxes to biamp using home built crossovers, I was taking electronics in high school.
It's been a long journey, but when talking musicality over ultimate slam, simpler is always better.
Question, have you ever tried vertical biamping with a true dual mono designed amplifier? Absolutely no sharing of anything other than a power cord. In essence four mono blocks, still allowing the use of extremely short speaker cables unlike horizontal. Still allows active crossovers etc, again all the benefits you claim for horizontal without any of the negatives, plus all of the advantages of placing the amps closer to the speakers.
We tried many , some like audire had separate psu down to seperate power switches. Its the same for Monoblocs vs dual sharing the same chassis , always found monoblocs seperate and apart to be sonically superior to any sharing the same chassis..
Cant say why for sure , but they did , there is a lot of flexabilty with monoblocs , pertaining to speaker leads , interconnects , etc ...
