which monoblock

I also in the past have had good results with Classe, & really like the sound of Canadian manufacturers. I am happily running Bryston now, I however hope to audition a pair of Sim Audio W-10's within a week, the Pass X600 will be auditioned later in the year. I can get back with you, & share my thoughts on all after my evaluation concludes.

I am using 0.5 meter speaker cables from each mono block to each speaker up front. This does restrict where the amp can be placed in releation to the speaker. It also means that moving speakers around for placement is limited to small incremental moves, which is really the idea anyway.

With such short speaker cables, long interconnects are implied. I recommend using balanced XLR interconnects and a fully balanced pre or prePro, and fully balanced amps too.

Another mono block suggestion is the Boulder 1050. But htey aren't inexpensive.

I went through a similar search, and ended up buying a pair of Theta Digital Enterprises. I couldn't be happier. They are vey musical, and have incredible soundstage depth and width. The instrument separation is the best I have heard, and all instruments/voices are presented in a very natural, convincing manner. For the rest of your system, you could configure a Dreadnaught II as necessary, and have closely matching amplification at a fairly reasonable price.

Audiobugged you are more than welcome, to let me know your thoughts once you audition all that gear,And the rest of you guys, thanks a lot for your inputs.Any other susgestion?

probably more suggestions than your interested in! :)

i used surface wiring for all the amps and speakers. where "surface wiring" means no in wall interconnects and no in wall speaker cables. just cables on the floor. it keeps the runs a lot shorter, and allows audiophile quality cables for every single connection.

i used a stereo amp for the rear channels, no benefit to mono's back there.

after the amps, I used a separate power circuit for the front end gear, feeding a PS Audio P600, and then all the front end is powered off that. the video has a separate circuit as well.

don't under estimate the cooling, especially if you select pure Class A amps. a cooling budget of 2-5 tons, depending on gear, is not unreasonable.

what is reasable for amps depends on room volume. if you don't have the cubic feet, save money, and don't buy the watts. if you do have the cubic feet, don't hold back.
