I haven’t seen much about a direct comparison between these two amps. Most of what I’ve seen compares these to the BHK250. Anyone have direct experience with the M700 and M1200? What differences can I expect from the tube integration in the M1200?
I don’t really care about more power as I use very efficient speakers (normally Klipschorns and Tekton monsters).
I had both sets of amps at the same time. I couldn’t justify the additional cost of the M1200 and I don’t want to get into tubes again.
They do sound different and the M1200 is a bit “better”. I am very happy with the M700’s!
Thanks kline42. Mind me asking why you don’t want to get into tubes again? Too much maintenance?
Tubes are absolutely no bother. If you are using the 6DJ8, 7DJ8 and their equivalents in any PSAudio product they are good for a long time. I pulled 4 Phillips Miniwatt’s from my 300’s and tested them after 3000 hours and they still tested almost as new. I have a pair of 70’s Telefunken tubes in my BHK pre and they’re still going strong after 4000 hours. I don’t understand the concern? Tubes certainly go a long way to making these amps special.
I’ve owned both the M700 and now the M1200’s. For me the 1200 sounds better in my system over the M700’s without a doubt. The tubes are a big part of the magic with the M1200’s IMO. The tube input stage gives the M1200 more sonic character, voices are cleaner and the overall sound is better! The M1200 does a better job of extracting details with improved clarity then the M700. But if I owned Klipschorns I would probably opt for a preowned BHK 250 over the M1200/M700.
I also have owned M700s and now own M1200s. The M700s are fine amps and I would have been perfectly content if I’d never listened to the M1200s. To me, in my system, they sound better in every way and probably most importantly, enough so, to me, to justify the price tag. Things just sound more like live music. The imaging, the sound stage, the detail, the bass, everything.
Well said David. The M700’s are great the M1200’s are better!
I own the 700s and love them. I also use a Rogue RP1 preamp. The tubes really add a larger and airier sound stage! The combo of PS audio and Rouge is a great mix. If I was starting over I definitely would have gone for the 1200s.
A 700 loyalist here. They’re my first class D amps (not counting B&O Beo-Lit and Naim Mu-so ) . Prior, my rack had AB and pure A power amps. Each had their own flavour!
The M700s are driven by a BHK Preamp, and the tubes are doing their magic at every level especially with analogue playback. The M1200, though not on my upgrade list, is technically different technically from M700 & S300. Key differences that matter to me are lower distortion, and improved damping factor. So, bass is cleaner, and highs are more natural. ICE Edge + tube input stage = major step up from M700.
Not sure if my expeience is unique or just my imagination but after upgrading from the S300 to the M700 and listening for a while, I find the highs seem a bit more bright than the S300. The soundstage is much broader, the mid and bass is much better but has anyone else seen that difference on the highs?
And related, would the M1200 have a big difference on the high end?
How long have you had the M700s? If I recall mine were bright out of the box and took a long time to burn in. Search for other topics in the M700s and M1200s but I think PSA recommends a couple hundred hours before critical listening. When I got mine, I left them on 24/7 with the radio playing for a week before I really started evaluating them.
I did not notice the M700’s to be bright when I had them. What preamp/speakers do you have connected to the M700?
I did upgrade to the M1200’s because I NEEDED the tube input stage. There are other threads with good descriptions on the sonic differences between the M700 & M1200, but there is a difference in midrange and high end with the M1200 (smoother and sweeter).
I did not own M700 amps, and my previous amps were a set of Vicent hybrid mono-block that was highly regarded in TAS reviews. To me the M1200 sounded a lot better than Vicent. The high is exceptionally smooth in my system in fact.
I am currently using a Marantz SR5014 as my pre amp and driving my center channel. This is so I have the ability to view movies as well as listen to music. But when listening to music, I run the Marantz on Direct to bypass the center as well as the other portions of the Marantz.
It isn’t the best option for pure music but a compromise to watch movies and television on my 4k tv.
It just seemed there was a bit more shrillness on the highs compared to the S300.
But overall, the M700 is a great improvement over the Marantz amplifier as well as when I hooked up the S300.
