Mods for ARC preamp / amp

Thanks everybody. Seems like there are alot of pros and cons to doing mods to expensive equipment. GNS sounds like they're a pretty reputable company. My concern is if there's aproblem down the road ARC will refuse to work on the unit. Does GNS do repair work on the non-modded parts of the unit. If anyone has had the unfortunate experience of having this happen, let me know.
Thanks,
Erik

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.

I can't really see buying a product that expensive and then turning it over to someone to hotrod. If the sound is not to your liking, move on and try some other gear. If a ten grand pre is so bad it needs to be sent out for mods, then imo, it must be really junk. Also, I would think the resale value would drop radically. Never buy used gear that has been modded. It is yours for life.

I agree with you. When a player is modded the flavor of the preamp is now changed from what the original designer wanted. This does not mean it will always be better. If you don't like this manufactures sound move on.

I agree with 6550c and Jwm 110%. It is time to move on and try something else.
