Best redbook-only CD Player under $10k - Bryston BCD3, Resolution Audio Cantata 3.0, ....


I’m interested in hearing thoughts on great CD players under $10k.  I prefer single box and not separate DAC and Transport.  I’m ok with high quality used gear too.  I’ve read good things about the two players in the title and I’ve heard the Esoteric K03x and was impressed (it outperformed the Wadia 781i quite easily).  I’d be interested in hearing if anyone did some side-by-side comparisons too.  I don’t have any SACDs so I don’t need that functionality.  Thanks!

Ayon CD5s used or new Ayon CD35se. Robust tubed power supply and output stage, class A preamp with analogue volume control included. Best I have heard and I have heard many.
Yes the Ayon CD5s would be a good used choice, as it uses 4 x PCM1704K R2R multibit converter chips.
But the 35se to me would not be as good for Redbook, as it can do sacd which would mean it has to be a delta sigma converter of sorts, not the best way for converting Redbook.

I love my Esoteric player with the Burr Brown PCM1704 R to R ladder Dac Chip.  Sounds so analog like.
I recently purchased the OPPO 205 (My 3rd OPPO) which has probably the best DAC in the world the  ES9038PRO DAC. They also produce UHD equipment. Their engineering skill is obvious every time I look at a blue ray or 4K disk. The same is true for their 
analog balanced output signal into my Pass Lab amp from CDs. I really don't understand why anyone would pay the price for the so called reference CD players when they can have an OPPO. There are simply engineering limits on what a DAC can actually do with a CD
and OPPO has them solved to a level that should satisfy anyone with an excellent system.
Look at the Sparkler Audio S503 Smart CD Player. I have listened to this numerous times at Charney Audio (Dealer). Every time I’m overly impressed what this little cd player with the NOS TDA1543 can do with red book. The player is $1750.00, save your money!  If your in the NY,NJ,PA area you can check it out at Charney Audio.
