R2Rs are back on the market from Analog Devices. Schiit is using them in almost all their DACs as an upgrade.
Now, i'll debate that they are hands down better. I had a new schiit BiFrost MultiBit (R2), a MSB Gold Full Nelson, and a Theta DSPro Gen 2 - and we listened side by side, back and forth. Frankly, different but very, very close. People worry too much about chips and not enough about execution- everything from digital filtering to power supplies to jitter reduction etc etc
