Tube or R-2R DAC for Tube System

I had been using a DAVE + M Scaler as input to my Eddie Current tube headphone amp, and ended up replacing it in that chain with a Holo May R-to-R DAC, which I liked better there. I've since moved the Chord gear to my 2-channel system to replace an MSB 'Analog' DAC.... 

I've had my Musical Paradise mp DAC mk3 for a while.  It has user changeable caps (no soldering) and uses both 5 and 6.3 volt rectifiers, and 12 or 6 volt signal tubes.  You can even change the chipsets from AKM's to ESS Pros.  I've done a couple r2r's but keep going back to my MP.  It will do up to DSD 512 and will handle high sampling rates.  I like the fact that I can change to sound by swapping tubes and caps.

@hshifi -  "I would say stick to chip based DACs with tube gear"  Not sure how you came to that conclusion.  Just finished a 4 hour listening session with tube Sabre 32 bit chip dac and a R2R DHT dac in an all tube system preamp and Class A mono blocks.  We all said to each other, that not one of us has heard any system ever that sounded like this, ever.

Happy Listening.

I like the dsd converting dac. Psaudio and Marantz sacd 30N . best of both worlds . smooth and not too clinical .

@bigkidz,
That sounds like a very fun listening experience. I know that you have several transports to choose from. Were you all using the Pro-Ject RS2 Transport?
