I have purchased 11 components from PS Audio & the only one I had to send back to the seller was a used Power Plant. Everything I purchased new has worked fine in my system.
All I was told was that the release is now in July because the parts order they were expecting was delayed. I suspect this effects all models but that’s just a guess.
… plus the trade-in deals have been good to me. Built into the PSA pricing structure IMO.
The Meitner is a winner IME.
Good point as well. But, you know, when it feels like you got a special deal it makes the equipment sound better.
My M400 order is now in queue. If the stars align, maybe before the end of the month I will be able to do a full comparison over the 4th of July week.
Did you sign up for the waiting list or talk to someone at PSA or both? I specifically asked about end of June but they would only say a July release (barring unforseen problems). Have you heard anything different?
The parts are in, and they are in the process of putting things together. A few integrated amps are first in line. PSA is closed from June 27 to July 5th, so it is unlikely that enough M400’s will be completed before then to meet all of the demand. That is why a July release is most likely as you were told.
Your best bet is to call sales directly.
Thanks for the info. I talked to sales end of May and have had emails since. In my case they weren’t ready to take my order. I wonder if the parts they got in are not all that is needed for the full line. I’m waiting on the M800 and S400.
It would be nice if they would take orders now. It would make the wait easier.
Are you sure? 
The M400 is 200 watts into 8 ohms and doubles to 400 watts into 4 ohms. The specs indicate it delivers Class A bias of 30 watts @ 8 ohms.
Does the Class A bias wattage increase into 4 ohms which is approximately the average impedance for the FR30’s? Or is the Class A limited in some way to 30 watts max?
Ya got me there, but I do have a case of Sauvignon Blanc that should help for a week maybe.
Very few amplifiers made actually double the class A output power when impedance is halved, if I had to guess I would say it either stays at 30 watts of class A into 4ohms or drops to 15 watts into 4ohms.
Thanks, but that guess might be invalid.
For what it’s worth, PSA seems to be updating the M800 product page (did not check the others). There are now some performance graphs which will interest some.
The 60 day trial period has gone back to the usual 30 day. Since the new amps don’t have handles I thought they were allowing 30 days for back recovery and then 30 days audition. Stock up on those pain killers.
Ok, but I’d say let someone from the mothership explain how things work exactly, please. As a first thought from a non-expert: it should make some sense to declare a wattage at a certain ohmage and expect a change if one of both variables varies. On the other hand, a stable amplifier (under a dynamic music load) can be expected to maintain its current (?).
I saw someone ask a similar question regarding the PMG Signature power amplifiers’ Class A wattage a few days ago. However, I didn’t see any response from the Mothership, aka PS Audio engineers. So, I’ll try asking it differently.
What is the Class A wattage of the PMG Amps when carrying a 4 Ohm load?
If the S400 provides 5 watts at 8 Ohm, how much Class A power does it deliver at 4 Ohm?
Whether a class A amp provides great current with lower impedance load (e.g., from 8 ohms to 4 ohms) depends entirely on its power supply design, rather than its operational class.
Given class A amplifiers are running wide open at idle, relatively few have the ability to produce double the current with one half of the impedance while operating in class A.
Yes, even some of the big expensive amplifiers rated for a given wattage into 8ohms can’t maintain a higher class A wattage into lower impedance loads. Some amplifier manufacturers use a dynamic bias to accomplish this, not static bias. The Mark Levinson ml2 monoblocks could do this down to 2ohms but look at how big they are, and only rated at 25 watts of class A into 8ohms and 100 watts into 2ohms with a standing bias current of over 4 amps.
Where did you get this regarding Mark Levinson amplifiers, any test data to back up power in class A doubling when impedance is halved. As Elk noted Class A amps typically do not double power output when impedance is halved. Class A amps run at full rated current regardless of load impedance. It is a design limitation. If power increases the amp is sliding out of Class A operation.
