Using two channel amps as monos?

You might want to try the configuration I'm using in a second system. It has two Forte 3's run as monoblocks. I've been very happy with the results. The biggest improvements were in the channel separation and soundstage/depth. Note that I've not bridged the amps. My set up was done by removing the +/- fuses from one of the channels in each of the stereo amps. This way you will have a virtual monoblock consisting of a dedicated chassis, transformer and power supply for the remaining amp to use without sharing these resources as in a typical stereo amp configuration. If the topology of your amp does not share anything other than the PS you would be good to go.

As I mentioned in my earlier post, I have been using two stereo amps as mono amps with excellent results. Perhaps a better way is to look at this would be to imagine 2 cars each with an available 300HP. One weighs 3000lbs, the other 1500lbs. Everything else being the same, which car will go faster? One of my reasons for doing this "experiment" was based on that sort of logic. The stereo amps existing power supply now sees only 1/2 of it's original specified load.

Note, I've only run single ended as balanced is not an option with the Forte units, wish it was.

So why do I run two stereo amps like this in the first place??? Well because I bought the first Forte amp and really enjoyed it! Since having hard to drive electrostatic speakers, I thought I would get another unit and have them bridged. Looked for and found a "deal" on E-Bay, but got jacked by the seller, one channel was toasted, guess he forgot to put that in the description?

Ok, what to do? Well, I was looking at two amps and three working channels or two amps and two channels and a spare amp module... or virtual monoblocks!
