How does the Phase Linear 400 compare?

Dinosaurs like the PL400 and 700 are fun to look at and (for some) to reminisce about, but sonically they cannot hold a candle to a $50 TPA3250 from our day. 

They can, however, deliver more slam but it'll be painful to experience and you'd have to find one that's still working.  A fool's errand imho.

transco,

If you are ever in Suburbs of Chicago, look me up.  I’ll play my Phase Linear 400, through my marantz 7, and you can compare it to my Krell KSA 50 and newly acquired McIntosh mc-7300.  

The Phase 400 is incredibly smooth and transparent.  

There is a lot of ‘Dinosaur’ gear out there that is in high demand.  In fact many (myself included) feel that some of the finest sounding gear ever came out of the sixties and  seventies.  

I was was a studio musician for years, I know what instruments are suppose to sound like, and to me the Dinosaurs do just fine.

I had a 700B for a while and with the speakers I had, Heresy's and Large Advents. It did just fine or as well or better than most anything else available at the time. It certainly sounded better than the Crown DC 300. It was built as well as most electronics of the day. Really insane build quality did not come along until Mark Levinson and Krell broke the mold. Not even Marantz was using mil spec parts back then and their switches were just as crappy as everyone else. I drove the 700B with a Marantz 7C.

I thought your description of Carver products was very accurate. Bob Carver was a genius and did things in a very creative way that most manufacturers did not do. I purchased a C-4000 around 1985 for $ 800.00 and I thought it sounded awesome with Pink Floyd the wall.  The Sonic Holography blew me away.  But after listening for a while I found it fatiguing and did not sound right (it did not reproduce instruments to my ears in a pleasing way).  I also purchased one of those Rubicks Cube amps used and was amazed at the power. I blew it up in a short amount of time and traded it off  for  an Audio Research SP 9  and Bryston 4B.    I never really noticed much of a difference with the Peak Unlimiter and Auto Correlator on the preamp. However I will never forget that wide unbelievably large sound stage of the Carver Preamp but it only sounded good with a few records that I owned.

jim55379,
I have a Phase Linear 4000 series one preamp (I used to have a 4000 series two as well).  It has the widest soundstage I’ve ever heard. The deepest too.  It also excels in detail and dynamics like no other and is whisper quiet.  But I can’t listen to it for more then a couple of hours.  The midrange seems hard and bitting after a while to me.  Not everyone just me.  It’s pristine, and I can’t seem to part with it, even thought it spends most of its life in its original box.  Years ago, it was my favorite preamp, but my taste have changed.  I enjoy my ancient marantz for preamp duties, that or my Sansui 9090db which seems to do everything just right.

Oh, and I had two Carver M-400’s strapped in mono giving 500wpc into 8 ohms.  They were pretty remarkable, but I never thought they were as smooth as the Phase Linear 400, which I’ve also kept over the years.  It actually works well with my marantz 7c.  

Carver’s tube amps are incredible.  Wouldn’t mind a pair of those, any of them.
