    Amps: Adcom, Earthquake, Sherwood, etc.

    I know this is one of those questions that may generate a lot of opinion, and has been tossed around a million times, but here goes. I am in the process of buying speakers. Not sure what kind yet, but my room size is 18x24x9. I want to get my amplifier so when I buy my speakers, I am ready to listen and test. Here are the brands/models I have narrowed it down to. I am undecided as to power, but I have the feeling I want more. The levels of amps are basically either 100, 200 or 300 watts per channel. Not sure if I need that much, opinions welcome. Since the Sherwood and Sherbourn are the cheapest, I will add the extra cost over these models for the rest. Parenthesis are rated 4 ohm power.
    .....................................8 Ohm (4ohm) ..........Added Cost:
    Sherwood Newcastle:......100w(160) x 7............Same
    Sherbourn 1250 A :......125w(175) x 7.............Same
    Sherbourn 2100 A : ......200w(300) x 7............+$500
    Adcom GFA 7707 : ......200w(300) x 7............+$1100
    Earthquake CineNova:....300w(600) x 7 ..........+$1700

    The Sherwood is the only model that doesn't have fault protection LEDs. I actually read one review that tested the Sherbourn 1250 at 150w x 7. I know the added headroom is nice and I plan on keeping my amp for a long time. The speakers I am looking at are mostly "brighter speakers". Most SNRs are around 105-110, the Adcom states 125 with THD of .009. The others are around .01. Obviously the Earthquake is the Mac-Daddy. It is the only one that lists a 2 ohm rating, which is 750w. Thanks for any reponse. And please limit your responses to these brands.

    I am an Earthquake & Sherwood dealer. I use the Earthquake in my personal system. I could have gone with Sunfire, Sherwood, ATI, ADA, Parasound, and a couple other brands. I really like the Earthquake and I recommend it highly. They run cool and are very bulletproof. I've never had a problem with any that I have sold. And the extra power you will have will give you more choices on the speaker hunt you are going on. PM me if you have any other questions.

      I would have to agree with Slayer about Earthquake they are awesome amps. The main thing is going to be $$$$$$ I personally like to spend as much money as I can on speakers vs other equipment. I personally believe that speakers are the MOST important, MOST noticable item that you can replace in your system. So if you can drop a grand in a good amp, then you will have another 700 to spend to upgrade your speakers. That is my .02 cents on the matter.
      The Bitterness of poor quality last longer than the joy of low prices.

        Slayer, Have you ever compared the Sherwood to the Earthquake. It is by far the smallest power rated amp, and I just wonder if I wouldn't outgrow it. I probably am looking most at the Earthquake or the 200w/channel Sherbourn. I could get the Sherbourn for almost half the cost of the Earthquake and it has some nice features, like dual power cords. By the way, does the Earthquake have a 12v trigger? I don't see it mentioned anywhere, and I may be putting my amps in the cold storage on a remote sequencer. Also, any thoughts on the fact that the Earthquake uses 1 taroidal transformer while the Sherbourn uses 7? Any benifits/downside to using one or many?
