What a better pre-amp Arc Ls-27 or Ref-3


I recently picked up a Ls-27 but I'm wondering if the Ref-3 would of been a better choice. If you have heard both I would like your opinion.

The Ref3 is very up-datable. I have a customer who may be bringing one in for update.
Gary (Hifigeek), please explain how the Ref 3 can be updated?? Is the update ARC approved? I ask because a friend who bought my Ref 3 might be interested. Thanks.
I have a rare REF3 LE that i had it through Steve Huntley when purchased new. The power supply was beefed up with another bank of premium caps (BG's) mounted on an acrylic board. Somewhat similar to what ARC is offering now with their SE upgrades. All resistors in the signal path have been replaced with Caddock's and some Vishay's and other mods i forget about. The only thing i do not have are the teflon coupling caps ARC is now installing with their SE upgrades. Those are proprietary so i would have to go with premium Vcaps.
If only money was no object!!!
I had him do similar mods for my REF2 Phono, DAC7, CL120's, but again, minus the teflon caps.
A sonic marvel.
I'm sure that HifiGeek can do as good a mod job as GNSC whether approved by ARC or not who cares! Personally, I didn't.
Steve has ceased modding ARC products a few months ago.
A shame. RIP GNSC.
Steve is a long time friend and he recommends me. There were very few Ref3's made that were designated Limited Edition.
