Power Amplifiers

IN 1995 I PURCHASED AN AUDIO RESEARCH D-400 MK 2 THAT WAS A STORE DEMO.
I HAVE PLAYED IT ALMOST EVEY DAY SINCE THEN. IT HAS NEVER BEEN SERVICED OR REPAIRED. I USE IT WITH AN ARC REFRENCE 3 S.E. PRE AMP THAT JUST GOT NEW TUBES. THE AMP IS SWEET AND MUSICAL, AND HAS PLENTY OF POWER. BEEN THINKING OF GETTING A NEW REF. 160S AMPLIFIER BUT CANT SEEM TO LET THE OLD ONE GO. IT'S BEEN A REAL PLEASURE OWING IT.

A 2000 Mark Levinson 383, now with New capacitors and service. It Will be with me for the next 15 years too.

I have a Adcom GFA-555 amp still in use since 1989. Great sound. Super base.

My main amps are based on a pair of Altec 1569A monoblocks.  The peerless transformers remain, it was totally gutted and expanded into a 125w. voltage regulated (not ultralinear, triode or pentode type) amp with low global feedback and twin 3" X 7" electrolytic storage caps. 

My other audio system has a Dynaco ST70 but with new huge storage cap, terminals, RCAs, SS rectification (kept the 5AR4 tube for slow start-up) and is transformer tapped to voltage regulated type use.  It has outlandishly stunning bass compared to a stock unit and reduced global feedback.  Both systems use SR blue fuses.

My two video systems (75" Sony 900 series) use 1978 Yamaha CR-620 receivers.

I have a space EAR 890 as backup but it's not in the same class as my main amps but is a very similar sounding amp to my Dynaco ST70.  

1999 Plinius SA100Mk3  Ralph Abramo of Galbo Design www.pliniusrepairs.com (pliniusaudiorepairs@gmail.com) His upgrading is transformational. 

1998 Plinius M16 pre originally owned by Gary Morrison, ultra tweaked… eventually to be upgraded per above. Call Ralph!

Since Ralph did his Deluxe Mod Upgrade on the amp there is a juicy difference which will keep this duo in my rack another 20+ yrs, when I turn 95! Dynaudio C1 Signatures never sounded so good and prior ProAc 2.5s would have loved it. What fun! Jazz Lives!
