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.

What about between a McCormack DNA 0.5 and an Aragon 2004 Mk II? Both rated at similar output, but the McCormack going for several hundred dollars higher. There is also a McCormack DNA 0.5 Deluxe, that runs a bit higher. Not sure how much better it is than the regular 0.5.
B&K 200.2 or B&K 200.1 monoblocks. Your Monitor Audio speakers will benefit from the mosfet output stage. Not sure if both amps are in current production. On the used market these are a steal.
I can't speak for the McCormack, but the Aragon 2004 Mk II is a lot of amp for the money and should drive and control your speakers with no trouble. It certainly outclasses the Adcom, IMO, as I've owned both. You should be able to find it for less than your $500 budget as well.
What about between say, B&K Ref 2220, Adcom 5500, Acurus A250? Only thing on the B&K is that owner is asking $650 and can get new Emotiva XPA-2 now for $699. As of now, no good Aragons listed on Agon.
How much do you want to spend or what is your budget? Personally I would go with the Bryston over the amps you have mentioned. I had a GFA-5500 many moons ago and it ran very hot but was an upgrade over my old receiver thats for sure. The 3BST you mentioned will sound much better than the Adcom.
