Pro amps


There seems to be a lot of discussion on some other forums regarding pro amplifiers. Seems that most people that took the risk and bought one have no regrets and will never look back at "home theater" amps again. Most of them say that they wish they had discovered pro amps earlier as it would have saved a lot of headaches experimenting with HT amps. The general consensus is that upon first hearing one installed in their system they are completely floored and cannot believe the quality of sound from these amps. Crown amps are one example. They cite extreme amounts of current yet some of the amps weigh all of 26 lbs. How can that be? Anybody have any thoughts on this?

I've heared crown, under less than optimal conditions, but it definatly sounded pretty good.

I got the impression it was less refined than high end stereo amps.certainly had a lot of impact and slam though.

cannot comment on weight of these. Could they be digital amps? Digital generates less heat, therefore needs less heatsinks, and can seriously cut down on weight and size
Slappy, no they're not digital but that brings up another point. The Carver Pro ZR series amps are digital. Anybody ever hear one of these?
I've not used / worked with Crown amps in a long time, but their older models sounded hard, bright and sterile. They were built quite well though and you could pound on them night and day, hence their popularity with the Pro Sound crowd. My guess is that they probably sound about the same ( give or take ) as they have to employ gobs of protection circuitry in order to keep from blowing up during less than optimal "pro" use conditions.

I've got a Pro amp here that i'll be hooking up this week. It is an AB International 1100A, which is rated at 525 wpc @8, 850 wpc @ 4 and 1100 wpc @ 2 ohms. I bought it for my "cousin-in-law's" PA system. Nothing special about this model, so don't read too much into the fact that i bought this one. I snagged it because of what i was able to find it for on the used market. At $380 including shipping, i couldn't pass it up. The fact that AB International has been building Pro Sound gear for 25+ years tells me that they've got to be at least half-way reliable to stay in business that long.

Some of the other "Pro" amps that i've seen people raving about on the net are WAY under-designed from what i can tell. Then again, they may work fine for specific applications, but i really don't think that they are suitable for use in a "high end" system. That's just my opinion though based on the information available to me at the present time. Others obviously think differently. Sean

Prp Amps are designed for a different purpose and I would stick to Home Audio designs.

As far as the ZR amps I know people that rate them over the Panaxonic Digi Amps which I have and they have both. I happily use the Panny and if the ZR is better I would consider it.

Other amps to consider used are Plinius and Sim Moon which are great pieces. Sim Mooon if you can afford them and a Plinus 2nd. I was talking to a dealer yesterday and he convinced me of the great value of the sonic attributes which the Sim W-3 has. I want one bad!
