I'm a huge ARC supporter. I own a VT200, and have owned several other pieces of ARC gear including the LS25 pre. All are excellent performers, extremely well built, with possibly the best reliability and support in the industry.
But if $1600 is within your budget for a new pre, I have not heard a better pre than SAS. Hand built with great care and dedication from a truely gifted designer, Steve Sammet. He is a fellow AC'er, and offers a generous audition policy, and he personally stands behind everything he builds.
