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.

All that being said, I would like to point out once again, that after a year and a half owning the amp, -as one of the original heretics who "dared" wade into the dark pro-audio waters, this is the best amp I have ever heard, owned and heard plenty, and plenty good. It is for this reason that I caution that the amp is so damn good, for those of you contemplating one, please note, the mods are by no means "necessary" for ultimate enjoyment. And yes, it STILL reminds me of an exceptional tube amp, coming dangerously close to SET, "to these ears, on this equipment, in my environment." I know what real instruments sound like, and have the advantage of perfect pitch. The amp 'matures' over a six month period....Passive preamplification and non-oversampling source for the Redbook crowd most strongly advised. Value Value Value.
Tayfiji,

Can you tell us what mods were done to your friends's ZR? I am about to look in to this matter for my own ZR1000
Eldartford, ...if ALL of those amps are ZR's, I want to come to your house...I cannot imagine what that is going to be like in a couple of months. It may be of interest to know that Ashly also has Tripath amps, 4 and 6 channel muscle amps which look pretty good as well, and they have an impeccable reputation for quality in all their products. Crest, Crown too have digital switching amps which should be explored. Either way, the pricing for all these brands has been revised downward, the last 12 months, due to market conditions, and decreased overhead associated with production by way of increased efficiency, less heat output, lesser component requirements, etc. Vive le Revolution!
Sean, the best answers are to be found at the ongoing threads specifically on the Carver Pro ZR Tripath amps and modification discussion, at audiocircle.com.

The short answer to your question is that from what I am seeing, they are pretty much load-invariant. I sat and listened to a ZR1600 cruise through difficult and highly dynamic material on a pair of Maggie 1.6 which were enjoying that particular combination ALOT. Resistive loads don't seem to worry these amps at all, nor do wildly varying moduli. Further, they run merely warm to the touch. I have twice read that some are buying them for their Apogees, which kinda says it all.
I have it on good advice that Carver Pro has already tapped Stan Warren as a consultant on the matter of a stripped down audiophile version, doing away with all the ancillary circuitry, such as the junk op amps and clip limiters up front, and some more useable audio jewellery on the back, with a view to producing a great amp that does more, for less, and come in 'under the radar.' This movement is currently under way. Stay tuned.
