I have the Ref 110s (driven by Ref 3). They are phenomenal amps. I have not heard the VS-115s but my dealer says the VS-115s deliver 80-90% of the Ref110s at 60% of the cost. So they no longer keep the Ref110s as floor demos, preferring to have the VS-115s which deliver so much for a lot less. Some folks are willing to pay the premium for that last 10% of performance others are not. It is a very personal decision. Are you able to audition the 2 amps side-by-side?
PS: You have a great system. Wish you continued enjoyment with whichever amp you decide to go with.
