Most of the "State of the Art" equipment is lesser known brands. There is plenty of choice in Denver with big brand name dealers like Listen Up and a couple of underground dealers that sell the "special" equipment. Give them a try.
Check out Exemplar for DAC's or of course DCS. Wadia is good if you have Steve Huntly hot rod it. Also, EMM.
Great tube pre-amps would be Aesthetix, Joule Electra, LAMM, or if you can find one, a used Essence.
LAMM would be a great amp for Wilson speakers. If you can find one, an Essence amp is killer but they are out of production.
