Kim, I use the Wheatfield HA-2 which in my opinon is the smoothest sounding amp on earth. All the equinox does to my system is compliment what I am trying to achieve. Never, have I heard a simple cable change that transformed a good system into a killer one. Also, it is unbelieveable to me how detailed this cable really is being that it is so musical. Usually, you pay a price for a really smooth system, and that price is detail. Not with this cable, no way.
As for how the Equinox will sound in your sytem, with your tastes, I don't know. All I can say is with the last 2 purchases I have made, I truly believe the upgrade path is over. O.K. I might play with different interconnect, or tubes, but the rest of my equipment stays. PERIOD!
