A little additional information - new to the forum, and also have a new pair of Omega's. Like many folks here, my system is regularly on 10 hours a day, so I am in the same position as zmaggio described. I have a Decware Super Zen, but am uncomfortable running it that length of time.
I have read many reviews indicating Rega would be a great match. I am also exploring Heed, and want to learn more about the Cherry amps. With other speakers similar in design, I did this with a serviced vintage Kyocera, along with a Linn Majik-I. If you like older gear, something along those lines might work for "day use"; Luxman has been recommended to me.
With the Omega's, I want to up the game a bit, so will be interested in seeing what those with experience have to say. Thanks!
