Mods for ARC preamp / amp

I have had the following ARC products modded by GNSC over the years with stunning sonic results. Highly recommended.
PH3SE, LS16MKI, REF2MKI, REF Phono, Classic 120's.

I currently have a REF3 LE and a REF2 Phono at GNSC being modded as we speak.

Visit their website.

To Rgurney,
REFERENCE 3 LIMITED EDITION (2009)
The last approximately two dozen REFERENCE 3 preamps built was designated "Limited Edition". It has several unique cosmetic and performance enhancements. Cosmetically, there are natural metallic-finish handles to match the natural anodized Limited Edition front panel (black not available). In addition, the words "Limited Edition" is printed directly below the Audio Research logo on the front panel. Under the cover are higher-performance proprietary output coupling caps that boost the performance of the Limited Edition beyond that of the original version.

It's unclear how many of those 25 units were sent to North American dealers.
Word is very few. Most went to Europe and Asia.

To the rest: If you think your ARC gear (whatever piece you own) sound amazing; think again. To put this into perspective, i just sold my modded PH3SE to a guy in California who had a stock PH3SE. He sent me an email yesterday. See below.

Hi Sly,

Just got the inputs loaded for 125 ohm (what the Shelter 90X likes) on the high level and have it playing now. Definitely and improvement in resolution and the extra gain isn't any noisier so the noise floor is much lower. I'm getting a small amount of hum but that's just working out the grounds and equipment placement.

Cheers,

GNSC warranty the work they do for one year and they can repair any amps and pre-amps ARC has ever produced. They will not perform mods or repairs on the CD players.
GNSC is not a backyard mickey mouse outfit. They have been in business for many years.
ARC will not refuse to work on a unit that has been modded by GNSC. There is a REF 1 GNSC modded for sale on Agon and the ad says that the unit was looked over by ARC and everything is in perfect working order.
No worries Ebe.
