First foray into separate 2-channel amp, 200wpc


Hi, I am thinking of purchasing my first powerful 2-channel amp, to use with my Yamaha RX-V1800 receiver. This is kind of an experiment, so I don't want to spend a fortune. I need to see if a powerful amp will take better control than the Yamaha of my Monitor Audio Silver 9i speakers I just picked up. I am thinking of a minimum of 200 watts/channel. I am looking at spending up to around $500. I will probably want to find something used here on Agon.

So far, I am most drawn to an Adcom GFA 5500 here on Agon, although I am aware there are many other brands in that level of amp. I am aware of Emotiva, and wonder if anybody feels a new or newish Emotiva will be better in any significant way than the 5500. This will need to be a good performer on both music and movies.

Or, since the Yamaha is fairly powerful for a receiver, is there a likelihood that the Adcom of something similar will not make a detectable improvement?

Any other suggestions? Thanks.

You might get more dynamics or control over your speakers by hooking up a higher quality amp to the receiver using its pre-amp level outputs, but your sound quality will be quite limited by the pre-amp section of the receiver and all of it's internal circuitry. This would not be the best way to get the full sonic benefits of a higher quality amp.
I am using a Adcom 5200, Sonic Frontiers Line 2, Dali Grands. Sounds pretty good for a ebay special being that my Classe amp is out of order.
You might try an Acurus amp - plenty of power, even the 150 watt version - a high-current design that sounds very good for the price. I've also owned a B&K amp around that price that was surprisingly good. You will be limited by the pre-amp, but it might be a good start.
