6.5 years on, I'll bet the OP has spent his $20K already(just a guess).
Between the rave review in The Absolute Sound and a look at the technology, there may be a new contender at $15K that would compete with the 6-figure big boys--the Bob Carver Amazing Line Source. You could pocket $5K for cables and room treatment, or some nice listening chairs.
I'd certainly love to hear them anyway. Bob Carver Corp. was bought by Jade (owner of Emotiva) in 2013, so I don't know if their products are stil made in Snohomish, Washington. If so, and if they have a factory showroom, maybe I could realistically audition them.
