Best sounding CD player

I’ll throw my REGA ISIS VALVE cdp/ USB DAC into the mix as a true contender and no pretender as a 55 lb heavyweight with a pair of XLR jacks as well of RCAs in the back panel with fully balanced, differential circuitry throughout.

it has its own USB input direct to its high-end DAC and a special future-proofing bonus: 

“ … Those worried about the viability of the CD format and getting your player serviced in the future, fear not. Inside the owner’s manual, there is a signature from the technician that assembled your ISIS, another tech that QC’d the electrical and mechanical systems and the tech that tested and archived not one, but two spare laser units. I think it’s safe to say that the ISIS will last longer than most of its owners and I appreciate this attention to detail, with CD transport mechanisms getting scarcer all the time…”

But

Luxman "u" is the previous generation,in the 8, 6, and 5 versions.

"x" is the current generation.  Currently only the 10 and the 3.  Surprised to find the "u"'s still listed on the Luxman website.  They will be discontinued.  I gather that the intention is eventually to add a third "x" in the middle--5, 6, or 7, don't know.

X vs U minimal difference 

@dvdgreco I'm looking for that Cary 306S now working or non-working if you know of someone selling one. Thanks 

I’d recommend separate DAC and a transport. If you ever feel the need to upgrade either, easy enough. You didn’t mention budget, but the Audiolab 6000CDT is a great transport, and a helluva deal at $600.

I prefer R2R ladder DACs, as Soix suggested there are great units for all prices from Denafrips, Musician, Holo Audio, Gustard……I prefer the Denafrips and Holo Audio DACs
