Old digital that still kicks butt

I've got a Sony 703ES circa 1985. It's sound quality is worthy of a unit from that era: http://www.thevintageknob.org/sony-DAS-703ES.html

I have a Naim nDAC powered by a Pardo T-XPS; it's seen off (almost) everything I've compared it to - Denafrips, Schiit's Yggy, Hugo TT, etc.  

The one DAC that was noticeably better was the dCS Rossini; while I' sure there are others I've never heard one that's noticeably/obviously better for anything close to what I paid for the nDAC and Pardo power supply - about $2.2k USD.  

And while I don't own one, I heard a Theta Digital DSPre Gen 3 that is still terrific.  Ditto an older Wadia.  

I agree the good old R2R ladder dacs sound more musical than any of the one bit or bitstream dacs I’ve heard. But it also depends on the implementation. I’ve had two players with 2x PCM 1704k (Krell KAV 300cd and Bow ZZ-8) that both sounded very nice (still own the Bow for its striking industrial design). But they were no match for the Krell KPS20i from 1995, which had 4x PCM 64k (one generation older R2R) in fully balanced digital mode. Over the years this machine has survived many newcomers from respectable brands (Metronome, Esoteric), so for me this is ’old digital that still kicks butt’. Even literally, as the bass slam of this thing has never been surpassed in my experience. I recently had it fully refurbished with a motor and servo revision, new laser, new clock, new caps, etc. I just hope it will run forever.

My modern, not vintage Naim ND555 music server uses the 1704 chip in an R2R ladder DA C.   It sounds pretty good.  I have no idea if this particular approach is the reason for it sounding good.  My old CD player, also a Naim CDP555 also had a ladder DAC employing that same chip.  Does that make me a fanboy?

Cary HDCD 306/200 w/ 8x1704's. When I sold my big rig almost 6 years ago, I went back to the Cary and was happy happy happy to hear it still more than held its own.  Just a great sounding player and DAC still after 15 years. Recently sold mine away to a local friend and replaced with an AMR DP777SE and the improvement is there, but not leaps and bounds....the CD77.2, now, THAT's a DAC and player of a different color.
