Looking for a cd source for my system.

At this elevated level, listen first! As well as Levinson try Wadia and perhaps Krell. All are good, but you need to find "your" particular flavour.
I think anyone with your gear probably knows what they like when they hear it - trust your ears!

There's a Levinson 39 cd player on sale in the classifieds right now for 3100. It is upgradeable too.

The Sony SCD-1 is a very nice unit.

The most versatile and the best-valued so-far in my list is Gamut CD1.

I have heard that there is tremendous synergy between Levinson components. One of my friends is a levinson guy, and he remarked that adding just the levinson transport to the levinson DAC made a big difference. He's running the 360S dac, audio physic virgo's and tranparent reference cables.
