Threshold Stasis S500 250 W/Ch Series II Class A/AB Optical Bias. Built like an armory! (98 lbs)
Mine was circa 1983-1984. I was once thinking of selling this amp but fortunately did not. I spent 2 months searching for parts to "re-cap" it (4 Mallory CGS type) I found a store which sells the units for $160 total. After replacing the caps, I was very surprised that they sound so good, much better than I can remember.
My passion towards this amp was renewed. I am glad I made a good decision to restore the unit. I love it!
Come to think of it, I was considering to sell this unit for just $600 before.
Has anyone tryed to use Dynaudio, B&W, Paradigm, or any hi-end speaker with a vintage amp? If so, how does it sound? What are the advantage and disadvantage? The reason for my concern is that I can not find info on such a match. It would be pretty intresting to see a match like Sansui/Dyanudio.
BTW, has any one heard about Phase Linear and GLI amps? If so, please comment on these. Thank you for concern and happy listening.
Hey pixcja---you need to enroll into the Audiogon Bluebook service. to answer your question, the 4100 sells for $2,000.00 new and roughly for $600.00 used. I looked it up in the bluebook.
Even if you are planning to make just one purchase, or sale on Audiogon, you NEED THE BLUEBOOK SERVICE!
oops, sorry for shouting.......
The D-79 series amplifiers from Audio Research were perhaps the pinnacle of "any" amp that company has ever made! The D-150.. in their day was at the edge of the art as far as high powered tube amps go,however...that said...they are the equivalent of the older MAC stuff sonically... with a soft, lumpy and bloated bass and a rolled off top end. Musical in a way- but pretty mediocre by todays standards in vacuum tube design. The later D-115 was a great amp with some serious balls that stomped it in every which way,and would certainly qualify as a true classic that can still compete sonically with much of the esoteric modern stuff of today.Destined to become a collectors item like the D-79b and rightly so! The original Grant Lumley 100m's also come to mind as well as the original 8417 version of the Quicksilver monos.Anybody remember the Radford st-25, or the Beard st-35's from Enland? both of them make magic!If you can get by with 35 watts/side the Beard amp can compete with just about anything out there regardless of price.
There are many I would like to hear again in the context of what I know now. My list : AEA A-620, Sony Esprit and AudioLab, Citation XX, Ampzilla (I own one, a son too), Infinity Switching amp with the cool blue lights, and the Kenwood mono blocks LM-07 i think is the model. I've heard some awesome music with these amps and some great older speakers which I would like to hear also: Fried W's, Mission 770's (awesome bass definition), Dahlquist DQ-10's, Hill Plasmatronics (what 10 grand used to buy), stacked Advents, ESS Transar's and AMT-1D's,.........
I have a Phase Linear amp that is almost 30 years old, and it is still cranking. I am going to have it worked on though, as I was advised that some of the internal parts need replacing from time to time. When I get it back, I will put it into a vintage system, that I just recently started using again. All of the other pieces I bought in the 70's, as well. It all still sounds great!
I've owned a ARC D-115 Mk 2, Dynaco ST-70 and still have MC-60's all of which are great vintage gear. So far as looks go, definitely the McIntosh amps which I still have. So far as sonics go, the D-115 Mk 2 is a great performer though I found the bass a bit fatter, not as defined, and the highs a bit beamy, and glassy at times than the better crop of current tube amps although it has plenty of slam. This amp has one hell of a soundstage and a great midrange and plenty of power, 100 watts. A real classic, I hated parting with it but you can't keep them all.
Most of the all tube ARC amps from the 70's and 80's including the D-70 M-100's, D79, D-250 are all quite desirable and great vintage stuff.
I've owned a Beard P-100 since about '94. Bought it used for $500. Put a little work into it: added caps for storage, brimar and mullard tubes up front, Svet KT-88's or better yet, GE 6550A's in the rear. I would think you'd have to spend $8-10K to get better sound. The amp has balls and slam and can be as delicate as a bab'e bottom-with Thiel's, or Martin Logans or whatevah!
I have a soft spot for vintage it's the only spot in my system where vintage takes it's position. I regularly switch between my Marantz 8b (put together as neat as a button), Futterman H3; still lifts layers of haze compared to any real world transformer coupled amp, and a totally tricked out Citation II.
One of my fondest memories was of a ARC D79 driving Beveridges about 30yrs ago..I don't think I've ever heard anything as good since...AJ
Are you talking about the luxman d-105u 18 bit tube cd player? i have one , it is a well built smooth yet detailed sound,it is well specified and has a host of good features, eg:fixed and variable output,display cancel,tube preamp stage,very nice vintage cd player , around the late 80s there were a host of well built cd players, Technics sl-p 999, stax quattro 2 , i owned both of these as well, back to the original thread my favorite vintage amp was the accuphase e-202 i had for a few years.
Precision fidelity C7A...for its phono section
Levinson M 27.5...worked damned well with any speaker I threw at it
PS Audio 2C plus...great sounding little 40 watt basic amp..responds well to mods...wonderful amp and can be bridged
McIntosh MC225...this is the one piece I regret selling a few years back..I should have restored it and modded it.
I Wouldn't call the ML 27.5 vintage just as yet.I bought mine brand sparking new about 8 years ago from BRACK ELECTRONICS up here in TORONTO CANADA,it was my first high-end piece and had to save my money to be able to afford it at the time.Having said that I absolutely love it and wouldn't ever sell it.Sound ,looks,build quality is all there plenty.But I don't think is a vintage at this point in time,perhaps in twenty years from now.
