True. I have tried loads of DAC/AMP combos, and many have a high noise floor. But Meridian Explorer is dead silent. So is Denon DA-300USB.

  And what about the headphone out? Actually, what I really want to know is the output impedance of BDP-105's headphone out, which I have.

  And you are going to do a review for Primo 8, if I remember correctly? Please compare it with SE846! Thanks!

Hi Alex, Appreciate for your effort. Just two quick questions: (a) How would you compare ODA with the Wire? Owen himself once compared the Wire with O2 and indicated that he could tell the difference between the two, if he listened critically in very loud volume. It would be great if you...

  I always wonder why it's so difficult to find a hiss free DAC/AMP combo. I mean, is it really so difficult? My iPad Air sounds good, is hiss free, and does a lot of different things too. On the other hand, all the DAC/AMP combos I have tried (Dragonfly, iFi iDSD, Geek Out) hiss with...

  What's the S/N number of your new set, if you don't mind?

  I thought the Sabre dac chip that you use, like most modern delta sigma dac chips, upsamples by default.

  Not necessarily "mess up", though. ER4P gets a "flatter" FR with added resistance.

  Thanks for the info. It's good to know how choices were made. So BB was picked over Sabre ES9018-2M, because the latter was unavailable at that time? I always thought that the choice was made, because the former is the only few DAC chips in the market that does native DSD. So 9018 does...

  Got a reply from Vincent of iFi about the effect of added attenuator/resistor on FR: "The ifi Attenuators are designed to keep this change of frequency response to an absolute minimum. Worst case, the drive impedance to the headphone is a bit under 3 Ohm (12dB attenuator) and under 1 Ohm...
