Which good discrete R2R multibit DAC & why NOS ?

In another thread concerning upsampling and upconversion in servers, mention was made by georgehifi :
¨Should just have a good listen to Redbook 16/44 PCM converted through a "good" discrete R2R Multibit nos dac.¨
Which would these be and why NOS ? Are there no R2R multibit DACs being made today ?
My Reimyo CDP777 although quite old has the K2 conversion and being one-box and top-loading made sense  to me at the time of purchase.
Most importantly, would adding an external R2R bring a noticible improvement or just be sidestepping ?

Thanks in advance

In this instance NOS means non over sampling not new old stock.

Also you own a great CD player I would think most Dac's would be at best a lateral move.

Thanks jond for the clarification on NOS.
Should have deducted as much considering context.

Which good discrete R2R multibit DAC


Can't remember where I found it, but here a list of today's manufacturers making R2R Multibit dacs, and this is getting old I think.

If you have more to add please post them up and the price, and the numbers are slowly growing.

 

Up to $3k:

Border Patrol, Monarchy, Denafrips, Audio-gd, MHDT, Holo, Soeskris, Metrum, Schiit

$5-$15K:

Audio Note, MSB, Metrum, Computer Audio Design, Aqua, LessLoss, Totaldac, Lampizator

$15K+:

CH Precision, Aries Cerat, Light Harmonic, Audio Note, MSB, Totaldac, Lampizator

**Special mention to MSB, Monarchy and Audio Note, who never gave up on R2R. Even after the short lived takeover of delta-sigma, for doing PCM Redbook conversion.

 

Cheers George
