From Home Theatre Review: 

"The LS26 is a fantastic preamp that does everything right. It’s simple to use, built like a tank, and sounds terrific. Think of it as a Ref3 with a large discount. Yes, the Ref3 is better, but unless you have the absolute best of the best components, cabling, power, room treatments, etc., it may be overkill. Nearly all enthusiasts will be blown away by the LS26, which will keep them happy for a very long time."
