I have been looking into upgrading the amps for my main 803Ds. These speakers do require some decent power.
I am currently using a Classe CAV-150 (6 channels X 150 watts), that I had set-up for bi-amping my front three speakers. Recently, I changed to connecting my five speakers through each channel. I found the sound was actually a bit smoother and open, yet less dynamic (maybe using the balanced connections helped the 803Ds).
I have been looking at getting either a pair of Classe CAM 400 mono blocks, or a McIntosh MC-402 stereo amp, or a pair of McIntosh MC-501 mono blocks. I have been looking for used if possible. The only thing I started thinking about however, is that these amps weigh a ton and also eat up a lot of electricity. They also need space to fuction properly (I'm somewhat already cramped).
I also recently started looking into the Music Fidelity 550K and 750K Superchargers. The concept looks very interesting . . . an informative discussion - http://www.htguide.com/forum/showthr...0+Supercharger
The 550K lists for about $5,000 a pair, and can be had for about $4,500 new. The 750K is new and the dealer is checking on the pricing, but we figure about $7,000 a pair, or about $6,300.
I really like the quality of sound that my Classe CAV-150 produces, but I also know that my 803Ds are underpowered. I listened to the MF 550K this weekend on both a middle-of-the-road Yamaha receiver, and on a pair of top-of-the-line Krell mono blocks (these were monsters) and a Krell pre-amp. Both were hooked up to pair of $50,000 Focal speakers that I loved, but, that's some serious coin.
The total sound stage was dramatically improved with the Yamaha receiver. The difference was stunning and was actually very good. The sound was also noticeably better on the Krells, however, the difference was more subtle. I would have liked to have heard the MF 750K on the Krells, which would have been more of a benefit over their already high output. But, even so, we could hear the difference in a more open sound stage.
Has anyone else had experience with these MF Superchargers, and am I nuts for thinking I may opt to go in their direction. At the very least, I won't end up with a hernia from lifting and moving monster amps!
Your thoughts are welcomed.
