Carver Pro ZR1600

Two of the three amps I ordered for my multichannel setup arrived today so I had to do a quick checkout driving the MG1.6 fronts and center. WOW. Everything you have heard about these amps is true. Perhaps, as others have said, they are particularly well suited to Maggies.

I did have a slight hum, as others have experienced, but activating the "ground lift" switch totally eliminated it. The amp is set up for balanced line input, and I suspect that the hum problem happens when you use a single ended input signal. (Not really a problem because the ground lift switch fixes it). The fan noise would be anoying if you can't put the amp in the cellar as I do. It is reported that in home audio applications you can disconnect the fan without overheating the amp. There is also a mod offered which replaces the fan with one that is much more quiet.

I was wishing for the Spectron amp, but the price tag for 6 channels is a bit steep. Three stereo Carvers cost about 1/3 of the cost of the 6-channel Spectron, and having the amps in three units is more convenient for me.

The Carver and the Bel Canto (I have heard) use a basic digital amplification control module made by an outfit called TriPath. (You can get complete technical details from their web site. The Carver amp schematic is also available on the Carver Pro website). The TriPath amplifier has some theoretical advantages over the Spectron design, but these don't necessarily translate into audio quality.

I agree with many others who have tried the Carver that it sounds great. The other digital amps may also sound great, but the Carver is the one that you can afford to try.

I tried 1 of the 1600 amps with my 16 year old Mirage m3 (86db) and it sounded more open, alive, more bass, and played louder than my Classe 400. I immediately sold the Classe and ordered another 1600. Both of the new 1600s cost less than what I got for my used Classe 400, and I can't wait to hear them in mono.
I am going to try and talk my brother into this as his set-up is quite similar.
