Downside to R2R Ladder DACs?

HI
I just bought a BODER PATROL SE I connected with a sonore optical module connected to a silent angel Z1
The DAC ( I change the tube with a mallard and the fuse with a synergistic orange) for les than 2000USD is absolutely fantastic much much better than my Meitner I owned
It is a R2R emotional DAC with a lot of energy
I cannot stop now listening my room library  so addict

@berti For some reason I can’t message you directly from your profile. Would you mind sending me a PM regarding your findings with BP vs Meitner?  Which Meitner DAC did you own?  How old?  How would you characterize the two sounds?  I have an Emm labs/Meitner that I am trying to replace and any thoughts on yours compared to BP would be much appreciated. I personally find the emm labs to sound really good but it is limited by sampling rate. To me it seems a bit bright and thin but I wonder if it is my speakers or the DAC. Thank you in advance if you would be willing to share your thoughts in a PM. 

@cheeg, that salesman you trust is untrustworthy.  Move on.

I have an ancient Wadia 15 that only plays redbook. Uses the famous Burr Brown PCM63 and sounds wonderful. If there has/had been drifting it still managed to outperform a bunch of DACs in our local shootout. One of these was the well known Yggdrasil which although very detailed did not provide the boogie and foot tapping. The decision was unanimous, all preferred, on redbook only, the Wadia to that Schiit  :)

So drifting resistors or drifting clouds or whatever, the message is use your ears.

I think in future when my wife wants to know which DAC we'll be using, I can say "play it through the 'drifter' my dear.
