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.

Mtrot,
If you want to experiment if the 9is will benefit with more power than 130w, you can assign two more channel from the rxv1800 to bi-amp the 9is.
To answer your questions:
1. a higher quality separate amp will improves sound,
2. fill with lead shot then add sand to fill up gaps will be the best way for mass-loading.
Hope this help

Imhififan,

Thanks, I am already bi-amping them with the bi-amp feature of the 1800. Using Morrow SP2 for the HF terminals, and some regular copper zip cord for the LF terminals. Mike Morrow says his cable will improve the bass quality(not quantity) if I wire the LF terminals with his wire as well as the HF terminals. Not sure if I want to spend $200-300 in order to find out!

Thanks for the tip on lead + sand.

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.
