Tried on different laptop with jRiver and Tidal, no problem. I suggest to try some other source just to confirm. 

Anyone noticed dropouts during USB playback? Connected to my laptop with FooBar or Tidal. Sounds like loosing lock for second.    Will try different laptop(have jRiver there) and cable tonight.

when I got to listen to Z1R at RMAF i know it will make some waves.. I guess it's more like tsunami now  . got mine today with TA. Lets refresh the memory  

  You can actually use this DAC for FM brocading    Kidding aside, I like when people write how they perceive music and what they feel when listening to music. What I dont like is statement describing ex. position of instruments, vocals e.t.c. Were you there when recording was made? Do you...

  Maybe its time to invest in automatic voltage stabilizer. Friend of my has similar issues after utility company "upgraded" infrastructure in his neighborhood. After a surge, he lost everything from fridge/TV to dimmers and power switches. Audio damage: $300 repair bill for two of his Monster...

  That's only one part which was important to me. I think its a no-brainer which one to pick.

  Personally, cannot stand the steps on the DACT(not enough). Can never adjust the volume to my liking. In my book RK50 is the king.  P.S. I had DACT on GSX MK2

  No, that filter will do nothing for DSD. I was listening to some redbook and hi-res material also last night. The filer is only be effective up to 96K PCM.    For redbook, both DAC's are performing very good. Slight edge for M1 for details. D1 is a bit more laid back.

  I think if you got M1 for DSD you might be missing a lot. TotalDac just wiped the floor with M1, and that coming from M1 owner. M1 filer was set in minimum0 and D1 treble fir was on.   

  I did not try the D1 alone yet. Hopefully more time coming weekend. Why did you return the re clocker?

  Also I had their preamp Nº326S on loan and it sounded great. Also very flexible.   Today got the M1 to compare with TotalDac, but will wait for the XLR switch to come.   

I have some dsd files in my collection. I did not care much about them until I played one on D1. Very pleasant surprise. Did you guys find that also, or it was the single malt  

  Check this thread:   http://www.whatsbestforum.com/showthread.php?6905-Totaldac-Reference-D1/page45   There is at least one person with Tube version but not sure if he compared the two. 

  Are you keeping the TotalDac to compare?

  Well, for me this was great update, not a cheep one thou. As you already know , the beauty of BHSE is honesty. I was going to roll some tubes, but know I don't think I have to.
