PS audio m1200


Hi,

I have an ARC Ref 6 preamp with B&W 803 D3 speakers. The M1200’s have a lot of power. I am going to look for a way to demo them. The specs list 600W into 8ohm, 1200 into 4, and stable transients at 2ohms.

I believe the speaker impedance curve has a 3ohm dip. Does anyone have experience to know if these amps are stable at 3ohms with enough power?

 

Thanks

Hello zpatenaude37!  If you have not made a purchasing decision yet, I recommend you try the Fiera4 from Starke Sound. It is new model of an amp whose mame ended in AD4. I have six of that discontinued model and am waiting for the new one to arive. They have a return policy and the new model  has a switching power supply and is not nearly as heavy as the previous version. The AD4s do a beautiful job with every speaker I've tried it on. I have five systems in the house and many sets of commercial and DIY speakers to play with. I have no affiliation with the company, but I've been building amps and speakers for over 50 years and know a winner when I encounter one. Needless to say, I have a very tolerant wife. The amp goes on sale during holiday periods for about $999. It's a bargain at the regular price. Check out their website, their name - no spaces dot com. It is a very remarkable product and is 4 channel amp, switchable to 2 or 3 chanels with the flick of a switch, no cable unplugging and replugging. Enjoy the music!.

Hi, I have no experience with the M1200's but I did have the M700's. I used these to drive my 4ohm Kef Reference 5's. Although these have a reasonably high sensitivity I do play them quite loud and the M700's coped admirably with plenty more to give. I was so impressed with them (and PS Audio) that I wanted to upgrade, the 1200's would of been a natural progression but I jumped straight to the BHK 300'S - no regrets there. I suspect that the 1200's will have oodles of power for your D3's. My advice is don't get too hung up on specs, they can sway you away from making good decisions.

I am not an audiophile, but have spent like one.

I have the ref 6 paired with a Bryston 4 b cubed.

 

I find if I want to crank it up the volume flattens out.

It was relayed to me that the design of the volume control on the ref pre is the limiting factor, something to do with gain.

 

Will a more powerful amp solve this? I don't think so.

On that note does anyone know if that vole control on the ref 6 can be modified?

Thank you all for the info and advice. I will continue to research your recommendations. 

 

And mossyrocks, it looks like those amps have 2 options for gain. Does it make a difference between the 2 gain options? And also, I am no expert either, but I never looked much into Bryston because the input impedance is lower than what is recommended for the ARC ref 6. Could it be due to that?

Gain switch makes a difference, but the ceiling is still there.

Can't comment on input impedance. The pairing was suggested and confirmed by multiple dealers.
