Enqueue is definitely not bit-perfect: I A/Bed with Fidelia, which is bit perfect, and Enqueue had some sonic issues. There was strange blurring on transient sound like the pick of an acoustic guitar, details seemed blurred behind the rest of the music, low signal detail was also grainy and unrealistic - compared with Fidelia which does not exhibit these problem. I was using a trail of Fidelia. I purchased Enqueue because I emailed the developer and he said it was bit perfect. Once I emailed him about what I heard he acknowledged there may be a coding issue and sent me a beta which sounded way better. however the beta expired. so I was without a player for a few days. I emailed the Enqueue dev about getting an update and heard nothing back. so in the end I had to shell out another $20 for Fidelia. I would stay away from Enqueue despite the better user interface, if your desire is for bit perfect audio and the best sound you can get. Fidelia is the next best option. Or wait (hope, pray, give up?) on the Enqueue dev addressing these issues. I am highly disappointed.
