It's time to replace my 2009 factory-modded Wadia S7i with a current R2R DAC.

John,

I may not be on point here, but I had a Hegel HD20 DAC and moved to an old Theta Pro Basic 3 R2R ladder for $500.

The Theta gives a lot of detail and is the best DAC I have had in my system.

Thanks for listening,

If you like me, cherish your PCM Redbook cd collection, then yes stay with an R2R dac. As nothing does PCM like an R2R ladder dac.
The only trouble is now the major audio dac converter chip manufactures don’t make them anymore, way too expensive to manufacturer a R2R dac chips compared to today's DSD Delta Sigma dac chips.
Hopefully the manufactures will wake up and see that now R2R lovers are buying today's discrete R2R dacs, then maybe they’ll start making them again.

If you search, I have listed somewhere a list of hiend discrete R2R dacs.
Here’s just a couple of many out there, I suggest you look at these very good sounding R2R dacs, which will make your DC’s sound the best. And you have a great transport in that Wadia S7i, maybe use it?
MSB "The Discrete DAC"
Denafrips "Terminator" (level 2 or 3)

Try Mojo Audio R2R Dac

Hi,

FWIW, just wanted to would add a comment to this older thread.

I was using an eight year CD player with a Phillips Transport connected to my old Theta ProBasic III DAC.

I upgraded to a PS Audio Perfectwave transport about six weeks ago connected to the same Theta DAC.  

The improvement is amazing. Much more detail across the audio band with a lot more PRAT and presence.

EVERY CD is sounding better.

Thanks for listening,

Dsper

Mojo Audio. Ben’s unit destroyed my Exogal Comet Plus in about four notes.
