Going from 5.1 to 7.1 -- Have Sunfire CG, Von Schweikert, PSB, Need 2 Speakers + Amps

    I'm planning to get the Outlaw 950 pre/pro whenever it

    comes out and I currently have a 5 channel Sunfire

    Cinema Grand, which does 200wpc into 8 ohms, and

    400wpc into 4 ohms, and generally speaking, runs cooler

    to the touch than most amps.

    I can't decide how I'm going to power the other two

    channels. I can either buy a 2 channel amp, or replace

    my 5 channel Sunfire CG with a 7 channel amplifier.

    I like that the CG is famous for not running hot. I

    hope to get a total of 7 channels where the amplification

    does NOT heat it's enclosed cabinet.

    Currently, I have Von Schweikert VR 4 Gen II's in front,

    with a Von Schweikert center channel. For surrounds I'm

    using PSB Silvers. I need to get 2 more surround speakers

    but I'm not sure what brand to buy. I'm leaning towards

    maybe picking up 2 more PSB Silvers, perhaps used.

    Any advice?

    I would get a quality stereo amplifier(perhaps a stereo sunfire) for the fronts and use the 5 channel amp for the center and surrounds. A seven channel amplifier(unless designed as 7 mono amplifiers in a single chassis) will usually have less power with all channels going than 2 separate amps that add up to 7 channels all other things being equal. How audible it would be is debateable.

    Will, Albert is starting to ship his new TS350 surround. Mine will go out Friday.It is a tripole design on the same plane as the Aerial 3s surrounds.A great match with the Gen III's.I have been waiting 4 months for mine and surround nirvana is almost her!

    Cheers,

    Steve

    Thanks for the suggestions. Onecall has the Sunfire

    stereo amplifier for sale. It's on clearance for

    *only * $2000, which is a little too rich for my budget.

    The Von Schweikert TS-350 Surround Speaker is wall mounted

    but I don't want to tear up my walls to mount it. It goes to

    40 Hz so it probably needs to be mounted pretty well. I could

    I suppose put it on some speaker stands instead, but that

    doesn't seem too optimal. Besides, it costs *only* $2000

    a pair, which is at or just past the upper end of what I

    can spend for a pair of surround (or rear?) speakers.

    Any other suggestions?

    Are there different requirements for side speakers than

    for rear speakers? The two new speakers could be used

    I guess, either on the side, or behind? Should I put

    the "better" speakers to the side, or in the rear?

    I'll be sitting relatively close to the rear speakers (about

    3 feet away), and somewhat farther from the side speakers

    (about 6 feet away). I'll be sitting maybe 10 feet away from

    the front speakers. That's how the room is layed out.

    Will,

    A very cost effective solution would be to get an Adcom 5500 2 channel amp for your two new speakers.

    You can get one for around a 1,000. It'll do 350 watts into 4 ohms per channel continuous. A very nice amp

    for a wonderful price. That would make a great match for another pair of PSB silvers. Or you

    could go with the PSB minis, they would make great surround speakers. Very unobtrusive.

    Thanks I'll look into your suggestion for an amp and

    speakers. If the stereo amp I get is less beefy per channel

    than my 5 channel Sunfire amp (which I think your suggestion is),

    I would probably use the stereo amp to power the side or rear

    speakers.

    Will,

    You should be able to get the Harman Kardon Signature 1.5 200x2 amp for ~ $450-600 on ebay, HK direct, or places like jandr.com. The 1.5 has a DC trigger and should run cool/slightly warm. I think Adcom amps have a reputation for running warm (my adcom gfa5300 does in a open rack).

    Ricky,

    Thanks for the advice to not get the Adcom amp

    since it can get hot to the touch, and to instead

    consider the HK Signature 200x2 amp.

    Am I'm putting the cart before the horse?
    I could use the 7.1 pre/pro as a 5.1 processor and then not sooner but later, buy a new amp and speakers. I mean, I don't have to have 7.1 the day the 7.1 pre/pro arrives, do I?
