You're in IC?
Have you visited Ref AV or Hawkeye Audio?
The folks at both stores are usually pretty good about allowing potential customers to listen.
You'd be able to get a flavor for the sound that brands such as Arcam, Rotel, Musical Fidelity, B&K, Integra, Anthem, and Classe provide.
If you aren't going FLAC / Computer audio yet, I'm going to second the Squeezebox suggestion. It'll provide you with a high end transport/dac/and preamp all in one package. If your current front-end is low to mid-fi, going with a SB is probably the best upgrade you could make.
