40th Anniversary Pre Amp and Repair History


I’d like to hear from anyone that’s using the Audio Research 40th Anniversary Pre Amp or anyone that has owned that unit in the past.  Did you experience any repairs with your unit?  I’ve had mine repaired twice in the last year.  It’s a bit frustrating.  Yeah, the unit is 9 years old but still it’s a quality, high cost piece that should last 20 or thirty years no problem.  Have you owned or do you own this piece?  Any problems with repairs?

Yup @stereo5, Simon was living in Portland, about a half hour drive from me (he has since moved back to the UK). I got to hear not only his impressive system (Magicos, VTL amps, ARC REF40 pre (since replaced with a VTL), DCS Vivaldi, EAR-Yoshino table/Durand arm/Miyajima cartridge, but also:

- His listening room, designed by Art Noxon (ASC) and built using ASC products. Though small in size, in some ways the best room I’ve ever been in, particularly the non-resonant walls, courtesy of the fantastic ASC Wall Damp constrained-layer damping squares.

- The Townshend Audio Seismic Podiums upon which his Magicos sat (on top of a concrete floor). Counter-intuitive, the Seismic Pods allow the speakers to "float" when nudged. This idea would seem to violate Newton’s law, yet the use of the Townshend Seismic products leads, as many UK reviewers have learned, to better sound from speakers than do spikes.

- The Herzan isolation platform upon which his table was sitting. I WANT one!

- The KL Audio Ultrasonic record cleaner. Simon cleaned my British-pressing LP of Cat Stevens’ Tea For The Tillerman (yes, the original "sunray" label Island), and I was immediately sold. I’m now saving for a Degritter.

- A full plethora of Synergistic Research products. Simon’s system was the "quietest" I’ve ever heard, not a hint of hum, buzz, hiss, or any other noise.

I also listened to Richard & Linda Thompson’s Shoot Out The Lights LP (UK Hannibal pressing), long a demo disc for me, and great music. It sounded astounding, extremely detailed and dynamic. Quite a bit more extreme-treble output than I’m used to (Townshend Audio tweeters were augmenting the Magico tweeters), and sound very unlike the planars I prefer (Quad ESL, Magneplanar Tympani T-IVa, ET LFT-8b). But we all choose our poison, ay? ;-)

ARC runs their power amp tubes hard, which results in lower distortion/higher sound quality, but at the cost of reduced tube life. They are not alone in that. Whether the same is true of their pre-amps I don't know. Audiogon member folkfreak had a 40th Anniversary until recently (I heard his system in which the pre was installed), I would PM him.
