Quality CD player + DAC + pre-amp in one package

Budget: $3000-$5000 new or used

I know Ayon has some products like this. But I'm totally new to this, so would like to know what are the options out there.

Thanks in advance.
Meridian 808.2i second hand...all-in-one and upgradeable to 808.3i someday if you wish. 808.i (original) is even less second hand. real world-class stuff at attractive price given the functionality. Listed here. http://app.audiogon.com/listings/meridian-808-signature-reference-cd-player-black

Read the Hificritic.com review online by Martin Colloms, and his ranking of the Meridian digital. good luck.
If you would be open to a DAC/Pre in one small package and a transport in another small package, then the Bel Canto DAC2.5 + the Bel Canto CD3t transport could be a good option for you.

If you are dealing with a space limitation, both of these sitting side by side are roughly the same size as a "normal" piece of gear.

Hope this helps.

Thanks for the suggestion guys. After careful thinking, I have to be careful as my amp input impedance is 30k balanced. That might limit the gears that would work well in my system.
Kzhtoo - the Meridian output impedance is 47ohms...i believe you should be fine with this. Hope that helps. good luck.
