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.

Gmood1...Yes those reviews and others like them is what got me all excited. The comment "uncanny ability to unbundle instruments" is exactly what I hear.

Sean...Undoubtedly multiple contacts on a switch or relay is a good idea. Sliprings that we use in the gimbal system of the missile guidance system that I work on have (for each of the many circuits) two brushes each with spherical tips riding in a v groove, so that there are four points of contact. But these are sliding contacts.

The sound of switches (unless the contacts are dirty, and resistance is measurable) is something that I personally don't worry about, but let's not get into that one. As to solder, some day when I have nothing else to do I will use about 20 feet of roll solder as speaker wires and see how it sounds. If 20 feet of solder isn't a total disaster, I will conclude that a few millimeters is OK.
Eldartford- I highly recommend you pick up some Neutrik Speakon NL-4FC cable connectors for you speaker connections. The CarverPro is set up to accept these. They cost about $5@ and are easy to install.

I think waiting to get a handle on the amps before doing any mods is a wise move. Stan Warren is reported to
be looking at these amps. I'd wait until a real pro like Stan comes up with a mod.

Have fun.
Kana813...Neutric Speakon connectors certainly look like excellent devices, but I do not need to frequently connect and disconnect speakers, so I think that bare wire clamped into the binding posts is probably best. (Least number of contacts, per sean's rule).
DMason - I listened to the Carver mods at The Eighth Nerve. The mods have been discussed at Audiocircle.
