In my humble opinion, the Music Hall CD25 is a great player in this price range.
I also liked the Music Hall the best of those mentioned here. Warm and musical. New it's $500 I think. I've listened to most of these, but unfortunately none in the same system. The Music Hall was paired with a Red Rose system, the others with less expensive systems.
I originally didn't like the NAD when paired with a NAD integrated, I found it mushy and indistinct. I liked it better paired with a brighter integrated (Cambridge Audio).
Been awhile since I listened to the Rotel and the Rega. I found the Rotel uninvolving (connected to Rotel gear) and eliminated the Rega because I didn't want top-load.
Hope that helps.
Do as I say, not as I do (as my stepfather used to say)! I've spent the last couple of years trying to extract my modded CD player from Stan Warren, who seems to have disappeared from the face of the earth. That was to have been my replacement, and would have (I believe) sounded better than any of the players we're discussing here. As it is, I'm back to the drawing board myself.
Best of luck, and enjoy your music!
You might consider a modded Toshiba 4960.
You can buy the unit for $100, it is a universal player and the mods are $300. It looks like a few guys are doing the mods and use a similar process.
Supposedly sounds very nice.
I am considering this myself as a way to try out SACD also.
I am not affiliated with any vendor FYI.
