>>Budd relax; a "high-end stereo amp" has no more "accuracy" than what you have now. Its frequency response is audibly flat and its noise and distortion are inaudible. You can't do any better than that unless a 4 ohm load gives problems or in the unlikely situation that more power is needed.<<

Wow. Thanks. So what you are saying, is that if my Pioneer 1014 handles the M80's without a problem, I will not achieve some "audiophile nirvina" if I were to go to a more powerful amp.

Very enlightening.

I had always thought that these ultra high end, very powerful amps, were, not to necessaraly play music loud, but to bring a clarity and realism to music at normal listening levels.

Never knew this a gospel, just assumed it.

"I do have a question though...anyone think I should push the H/K to 0 db reading on the dial? Should I try and crack the glass on the 75 gallon fish tank or on the panny plasma?"

Are you kidding? Of course you should. Personally, I don't think it will do it. Plus, you're too chicken.

Hey Bud,

The M80's sound quite nice at lower volumes. The only problem is that you will constantly be bumping them up because they sound soooooooo good at higher levels. When I'm alone, I can't hear the phone. Sometimes I'll just plop down in front of them with a beer and just listen till my ears hurt. Then get back up and do whatever task I was doing prior to the distraction. This is quite unusual for me seeing how I'm a definite ADD type person.


I have the 7200 as well. I've seriously been toying with running a Crown through the pre outs. Did you notice any difference with it vrs straight off the 7200? Do you have any type of treble / bass controls with the Crown? I have my M80's running through the Zone II and have no bass/treble control.

Maybe the one to ask about the Crown amp would be Bren,he is the pro when it comes to useing this type of gear.

My turn to help someone out!

There is like a thousand post plus thread at AVS Forums about using the Crown 402 and other pro amps:

New amp is making me grin from ear to ear

thanks Bud. That is the post the sparked my curiosity. I gave up keeping up on it and was hoping to speak with someone on this board that had some real world experience.

From what I've heard, from many folks running the M80's, is that they really shine when you pump more current to them. Not necessarily meaning that they sound louder, but fuller, if that makes sense.

I've used a bunch of Crown equipment, but since it's in an arena environment, it's all been in 70v bridged mono mode.

If you can find pro audio equipment that suits your needs and don't mind rack-mounting it and possibly dealing with the extra noise of cooling fans - and can READ THE INSTRUCTIONS! go for it.

They're not plug and go, but if you have some basic electrical knowledge... it's a good alternative.

Well, I did it and cranked the HK upto 0 db...100 nominal with 106 peaks...from ~12 feet away (Alison Krauss and Union Station). This is through M60's and an SVS 20-39 PCi. Sounds real, real good no harshness/distortion. This is also with the resistors installed on the tweeters.

Also happy to report the fish tank is still holding water.

Regarding the Crown. Setting it up really is not that difficult. It will be an unbalanced signal from your HK as you need an RCA to XLR interconnect for both left and right mains. The stock fans, OTOH, are loud and whinney (measured them at ~75db from ~1" (inch) away). I modded that by installing a resistor. Now they don't measure at all on the RS analog SPL. I wouldn't even know if they were on if it wasn't for the airflow that you can feel.

For HT the C/SL/SR are up +3db per the SPL meter at the listening position with the mains at 0. The Crown is rated at 260 WPC into 8 ohms...not sure on a 6 ohm load, for four ohms its WPC is 400.

There are no treble/bass controls on the crown, just power.

Here are the features:
# Selectable high-pass filter on each channel enables amplifier to work more efficiently when full band-width is not required.
# Pair of linear optocoupler clip limiters protects loudspeakers from being overdriven
# Housed in a rugged, all-steel 2U chassis.
# Efficient forced-air fan prevents excessive thermal buildup.
# Electronically balanced XLR inputs and touch-proof binding post outputs.
# Precision detented level controls, power switch, and four LEDs, which indicate clip for each channel, power and fault conditions.
# Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications.

This is how I have mine setup:
HK 7200 pre-R/L to the crown cranked wide open on the gains.
C/SR/SL are running off the HK directly. Sub via preout from HK. I listen to only two channel DSP thanks.

I have Zone II setup for the deck speakers, POS KLH, but hey it's background music and they cost ~$80 for the pair.

FWIW, I have been a participant of the AVS thread linked here (rmcgirr83) and also FWIW, am a moderator on the Plasma/LCD forum.

I like the Crown and am seriously considering its smaller brother the 202 for the center. Need to setup up the ART EQ for the sub first. Anyone use the Rives disk for that?

So, did you notice a difference is sound quality over running directly off the 7200? I'm not too concerned with the fan noise, the amp will be upstairs with the AVR, while the speakers are downstairs.

Dam, I'm almost scared to try this. I can't get the 7200 to 0 with my M80's now. I tried standing outside the house and bumping up the remote, but I think some of my neighbors thought I was a burglar, so I stopped. Plus, it was getting really loud and rattling things on the deck.
