Hey there,

I've got a sony ES receiver, and I'm looking for an external amp. I'd initially looked at Rotel RB-985, and still am, I suppose, but my receiver is a 6 channel, and the Rotel 985 has only 5.

So I was thinking it might be cheaper just to drive the three front channels with a good three channel amp, but they're harder to find.

Any recommendations on three channel amps???

Thanks.

Monty

    Adcom GFA 2535 (I think). Its 60x3. Not alot of Watts, but thoughs 60 watt amps can drive 500 watt speakers to ear bleeding levels. Adcom is clean, conservative and just a PLAINLY awesome amp! I love em! They go for 250-350 on EBay. There is one on there now.

    Nervermind that Auction already went off, here is one.....

    I think you would be better off going with 2 seperate 2 channel amp, one bridged to run the center, or maybe just using one of the 2 channels for now, and use the other one to drive a rear center in the future.

    Don't listen to Vr3, he lives in a closet. 60 watts won't do jack in a real room, and will not do well with the LSi's. Get a real amp.

    In a real room? WTH! My dad has a 20 by 20 den, these amps can drive about ANY speaker to ANY level without clipping, ADCOM is STABLE down to 2 effin ohms. Your full of sheat. 2 channel amps are the way to go though, leaves upgrading for 6.1. Listen to others advice broda (cer), WATTS MEAN SQUAT!

    MX has a point, 60 clean watts are better than 200 dirty watts, but watts are not everything. Damping, slew rate and input impedance are important to look at also. Then there are ohms, **** clean watts won't mean much if you've got 4 ohm speakers (LSi) and an amp that only does 6 ohms.

    I love the thd light on the adcom amps. Let's you know when you are at stupid loud levels. :)

    BTW I saw a GFA5500 go for about $450 today on ebay. That's so cheap for an amp that nice. Smokes my employee discount. Too bad I'm broke!

    Why dont you go with the RB-985 and pick up a smaller rotel stereo amp to either run one channel and dont use the other one, or bridge it to run the 6th channel. If you go this route then you are ready for 7.1. Rotel will make you much happier than adcom <B>IMO</B>

    Forgot to add: Current does matter, and I will completely agree with you that if you are listening at 50 watts, a cleaner 60 watt amp will sound better then a noisier amp that is capable of 200. But, if you extend the headroom of your 60 watt amp, its going to sound like ****, whether its a current demanding situation or not. This is all disregarding whether it blows up or not..

    If you have a decent sized room, if your speakers are less than 100 dB, and you dont have an AARP membership, you are probably going to ask more than 60 watts of power from your amps. And isn't that 'sometimes' what it's all about?

    Also, the man is talking about rotel, and I think we can all agree that any rotel or adcom 200 watt amp will be of higher quality than any adcom or rotel 60 watt amp, so the 60 watt clean vs. 200 watt dirty isnt even an issue. Not to mention an amp that is dirty at 200 watts, is probably pretty clean at 60, considering all that it has in reserve.

    Regardless, getting back to the nature of the post, one of our very own club members has a rotel amp that bridges to 110 watts up for sale in the flea market, it may be worth checking out.

    Adcom has THD in the triple digits
    and all their amps use the SAME components, so they ALL sound ALIKE. The GFA-545II (100x2) hits ebay at around 250-300. Cer, my Dad's speakers can hit 110 db with those 60 watt amps, their klipsch. The amps can take it, and you cant clip em, the amp tells ya when your gonna clip em witht he LEDS as mentioned above.

    That's what I was planning (RB-985), but then thought it might be cheaper to get a 3 channel amp and I wouldn't have to buy a mono amp on top of it for the sixth channel. New 6 channel Rotels, by the way, are a tad out of my price range.

    Decent 3 channel amps are way too hard to find it seems. I guess either way I'm in good shape (RB-985 or a couple nice 2 channel amps).

    Thanks for the advice.

    Check out Carver on ebay as well. I have seen a couple of 3 ch Carvers listed.

    A lot of happy Carver 2 ch owners 'round here... don't know any with a 3 ch model though.
    More later,

    By the way, if your driving the lsi's with an adcom 60 watter, its then 100 watts x2. Because in 4 ohms its 100. goodbye.

    If you can pick up a Rotel RB-993, it's the way to go. 200WPC into 3 channels. You won't find any at the store since Rotel has discontinued the product, however I was recently offered one for $800 (orginally sold for $1500 in 98 or 99) at AudioGon. I can put you in contact with the guy if you're interested.
