Just giving a first opinion of the PMG 400 Monoblocks.
Amazingly fast, effortlessly smooth!! Great bass/mid bass impact! Silent background !
Lighter than the BHK 300’s so easier for us 60 + year olds to move.
That’s a great looking set up!
Thank you for your impressions. Have me looking forward to when PS Audio gets their new shipment of m400 amps in so I can receive my pair.
Congrats on an awesome system. Your new amps look great with it. See that you have two of Paul’s Audiophile Guide books, The Stereo and The Listening Room, on top of those amps 
Welcome to the forum!

Are your amps plugged into P20, wall, or something else? I would be interested to know what brand of power cables and interconnects you are using. Thanks
Everything runs from a P20. Off of a dedicated line.
The P20 feeds #2 Stellar P3’s. 1 supplying the PMG pre-amp, and 1 supplying the PMG 512 DAC. All cables are “RAL”, (Revelation Audio Labs). They are the only cables I allow in my system !
The ABSOLUTE BEST cables,IMHO, no matter what you want to spend.
Synergy has worked for me ! After 50 yrs in the hobby I have figured some of it out.
I have spent the evening trying to bust these amp _alls ! No can do after 4 + hrs at 80 - 90 db.
They just continue to perform !! Un- flappable, so far!
Effortlessly SMOOTH !
“Synergy has worked for me.” I can relate to that statement, with almost as many years in this hobby I am now getting fantastic sound that with careful tailoring (especially in the form of isolation particulars these days) I am getting musical playback that just satisfies and transports me (albeit in a much different amplification manner, via SET 300B amplification).
I’m happy to read after 50 years you are not forced out of the hobby!
“You gotta start young if you’re gonna stick it out!”
Nice setup! Good to hear that they are lighter and sound better than the BHK300s. That’s what I have and the FR30s & PMG Pre. Just a quick question though - any idea what the underside of the PMG 400s look like? The PMG Pre looks like something from target practice on the range like an old country street limit sign (refer previous posts on the undersides of the PMG Pre etc). Or is it looking a bit more finished?
Thanks
Great question! I have a hunch that few if any will manage to look under those behemoths.
Thanks for that. Hopefully it wasn’t too much effort to get it out and flip it on its side. Just as well you didn’t go for the PMG800s! 
It is good to see that the bottom looks a whole lot better than the PMG Pre etc.
