Dated but still A rated DACs


Looking to purchase a great sounding used DAC , unless I can obtain equal quality on a new one. Your thoughts?

As far as dac chips go, the BB PCM-63K, and the PCM 1704 were tops but the king in my opinion is non other than the Philips TDA 1541 S2 Double Crown. the 1541 has a sound that is hard to describe. I have two custom AMR CD 77.1's one of which has already been retrofitted with a genuine 1541 S2 Double Crown and the other is awaiting transplant of my other 1541 S2 Double Crown chip. 

I should have mentioned probably one of the best bargains for a dac, the Monarchy NM24. People don't go after it because the name doesn't impress their friends but that thing runs PCM-63's and I have owned it before. It is above the fray and I think you can still get them new from Monarchy before his stock runs out. 
Just picked up a used CALYX w. Linear power supply for use with Headphone setup (Mac .. CALYX .. Icon(headlamp) .. LCD 3)
Amazing performer.  
The CALYX replaced a Jeff Rowland Aeris
However I think you may have a problem locating one
