Carver Pro ZR1600

Eldartford,

Carver pro's hands are tied. They can only sell to the pro market. All this Audiophile stuff took them by suprise. Do to legal reasons they can not market to the home user BUT you can buy a pro amp for your home system if you want to!!!

You will see different products to go with the ZR seris also. I don't think that Carver Pro will be doing the mods themselves, but as you can see,are letting some of the best people in the business do the mods and sell them.

Hope this helps,

Larry

El: You stated that Op-amps "should never be thought of as a linear amp".

If these are your honest thoughts on the subject, why would you buy a unit that uses Op-amps for hi-fi use ? After all, "hi-fi" is all about "high fidelity" i.e. linear replication of a signal. Are you now saying that the amp that you are happy with / raving about is a non-linear device, but you like it anyhow ? Help me to understand where you are coming from with these statements as they seem to be contrary to your previous posts in other threads. Sean

lkosova@yahoo.com...Trust the lawyers to screw things up!

sean...The circuit, which includes the OP Amp is linear, even if the open loop performance of the device is "junky".

An analogy might be the output transformer of a tube amp, where, when tested as a component, out of its circuit, its bandwidth and frequency response is "junky". However, put it in a circuit with appropriate feedback (usually derived from extra windings on the transformer) and the resulting performance can be superb.

Certainly there are different levels of OP amp quality, Noise being the parameter of greatest interest. Also, the type of circuit that the device implements affects the degree to which the "junky" characteristics are suppressed by the circuit. For a unity gain buffer amp, (which is what the OP Amps in the Carver ZR1600 mostly are) quality OP Amps would be of minimal value. (Resistors and Capacitors should be the principal concern). When you try to implement a phono preamp, with high gain and heavy RIAA equalization, it's a different story. Even the "best" Op Amps are not so hot in this application, which has given Op Amps their bad reputation.

I guess this is another case of a myth (Op Amps are always evil) that is based on a kernel of truth.

With arrival of the third ZR 1600 I now have the "final" setup with each ZR 1600 driving a MG1.6 with one channel, and a subwoofer system with the other.

It's true that Maggies just get better and better as you increase the power amp, and they ain't bad even with 60 watts. They say that the Carver ZR1600, unlike many conventional amps, gets better when bridged. Hmmm...1600 watts into four ohms. I better not try it.

El: I've got over 1400 wpc rms driving some 86 dB 4 ohm speakers. I don't know how your maggies would respond, but i know that this is how i was finally able to get my speakers to sing. I know that Mike aka Magnetar over on AA was using Classe' M700 mono-blocks ( 700 @ 8, 1400 @ 4 / 3 dB's of dynamic headroom ) to drive his Maggie 3.5's, which were slightly older but more expensive models. From what i can gather based on the path that he took after this, i don't think that he found this to be "dynamic" enough for him. As such, you better order another amp or two : ) Sean
