Is the PS audio M1200 D class amp worth buying or should I stick to A/B class mono amps

Does anyone have any experience with the class D PS audio M1200 mono amps, or should I just stay with a class A/B mono amp like the Cary SA-500.1 ES mono amps.


I have them since 3 years. Could’t be happier.

I had integrated AB before but never monos, so cannot do comparisons. They are quick and have plenty of power, able to sound easy and relaxed (tube-like) and never edged or bright.

i use to feed them to a P20 regens, other system all PS Audio, Innuos for digital and Gold Note TT, Sonus faber speakers.

Thanks, I was trying to decide between the M700 and the M1200, I have never owned Class D amps only class A, or Class A/B or class A tube amps.

I will have to give these PS audio mono amps a try, Xmas present to myself.

The Cary audio amps seem reasonably priced on sale now for around $6,600.00 which is the same price for the PS audio Stellar M1200 amps.

I'm going to see if I can find somewhere that I can try an in home trial to see which sound best in my system.

Instead of asking people how something sounds which isn’t going to help you because everybody has their own preference, ps audio has a 30 day return policy. There is no better way to see how something sounds when you can use it in your system and in your room, especially with class D amps. 

At the risk of engaging in hyperbole: they are SUPERB and an incredible bargain. I’ve used them to drive everything from Avant-garde Duo Omega G2’s to Martin Logan 15A’s and CLX’s to MG 20.7’s ALL with outstanding results. Wonderful tonal balance, ENORMOUS soundscape and wholly unrestrained dynamics! Never harsh. In fact, “tube-like”. PLUS there’s a 30 day in home trial period. Can you tell I like them? 😀

And yes, I was once tube devotee exclusively. ARC, VTL, CJ,  etc. But on my CLX the PS Audio were clearly superior to CJ ART 150. Those are all great amps, but the PS Audio bested them. 

caution: the M700’s are NOT THE SAME. They don’t have a tube input stage. 

I first had the M700s, which are excellent VALUE, but $6600 for the M1200s, not so much. Don't get me wrong, Im sure they are excellent amps (M Fremer kept his after review), but compared to what, price-wise? Long before PS introduced the M1200s, I bought a EVS 1200 which is based on the identical ICEPower AS1200 modules, but a highly tweaked product by Ric Schultz MSRP $2700!!! I loved this amp until I got a LSA Voyager 350 GaN amp, which trounced it IN THAT SYSTEM CONFIGURATION! Since then (about 3 months ago), I did a complete cable change with Ali-Express DIY HiFi, mostly Odin 2 silver and gold, and one component change; Audiolab 6000CDT replaced a dead Marantz HD CD-1 (used as a transport). I have long wanted to replace my Solid Steel vertical rack, thinking it interfered with the back wave of my EP 3.4 open baffle speakers (click on my UN to see pics). Recently, I came across an incredible deal locally paying $170 for a DIY solid maple table with a 5 x 2 x 2" top, so was able to pick it up. While breaking down my system from the vertical rack, I placed my Voyager (top off but resting sideways on the amp) on a chair. Alas, it slipped off and the top nose dived into one of the modules. It looked fine, but when I set up the horizontal system on the maple table, and turned the power on I had major fireworks from the right module: it's dual mono.

Fortunately, I never sold my EVS 1200, which I had not listened to since installing the Voyager well over a year ago. How would it sound now? Well, I am totally blown away, and would highly recommend it, but... Ric only made ~ 16 of them-sigh! If you don't have $6000+ to spend on the M1200s, do a search for the EVS1200 (or the Voyager; several available ~ $1500), FYI, I have yet to see a EVS 1200 for sale. Until I get a replacement module for the Voyager, I won't be able to A/B them, BUT, I am very very happy with my EVS 1200. 


I can't speak to the 1200 but I had the entry level S300.  Ran cool and provided years of trouble free service. 

I've had the PSA S300 6 months and it is a great sounding amp. The VTL ST150 needs re-tubing and that costs almost what the S300 did, on sale. The highs are smooth and the bass is so much better controlled. Enjoying the S300 a lot. So much so I have another brand class D amp on the way.



I've been running PS Audio M700 mono blocks for over 2 years running Mangepan 3.7i's.  Very clean, smooth great sounding amps.  I've never come close to running out of power and I will get on it now and then.  I was using a Bryston amp (250 wpc) prior and felt I didn't lose a step with the M700s.


That EX-B7 does not have enough power, I'm currently using an Anthem P2 amp and looking for more power and the TEK Audio EX-B7 has less power than i currently have, but thanks for the recommendation.

What are you trying to push that needs for than the 250 wpc the Kinki EX-B7's provide?

I have the PSA S300 Amp, and I love it. Plenty of sweet power and a relatively small footprint.

don't muck with that D tripe.

stay with an A/AB stereo or mono block amplifiers.

your ears will thank you, as will your cost from the wicked deep bass.


ive listened to a lot of them, as im losing strength in older age, and i listened to a lot, none gave me the hair standing on my neck and arms, or the cold kinda jittery in my chest when i hear my stereo after 24 hrs of idle, no matter what i play, i get the boosebumps all over, and i love it. 


Right now I'm leaning towards the Cary SA-500.1 ES for $6,600.00 on sale until the end of the year 500W @8ohms and 1,000W @4ohms class A/B mono amps.

I just picked up the Benchmark LA4 line amplifier that will be controlling the mono amps.

@alucard19 Congrats. That is what I use, and it beat all the other contenders I compared it with.
