Best sounding and reliable CD changer?

With a DAC try the Onkyo DX390. I have read the Integra equivalent is better but haven't heard it. My Onkyo's been running for years...

It's the Onkyo DX-C390

I had a Marantz 5 disc changer that I gave to a friend years ago that's still working, as is the one I gave to my son then as well. Reason I gave it away is that I got a music server, which fills the same purpose and is more convenient to use. I think that, or a similar computer audio piece, would be the better way to go, as Peter suggested above.

I still have a Harmon Kardon HK8350 and a Marantz VC5200, which is a DVD/CD changer. The HK is CD only. Both are 5-disc changers.

Both of these are very nice and sound amazing good, but even better through an outboard DAC.

Excellent build quality and have lasted a very long time.

This may be too budget for you but from direct experience I can vouch for this Sony player.

Sony SCD-CE595 5-Disc CD/Super Audio CD Player

I used this CD/SACD player to break-in all sorts of cables and equipment. I would put in 5 different break-in or test CDs and have it play for days/weeks on end. It never had any problems.

When I wasn't using it as a break-in tool and just listened to music is was very nice. No harsh treble and a bit laid back overall.

I've read the Adcom multi-disc changers from yesteryear were also very good. I don't know of any current multi-disc changers though.
