CEC DA53 and Aqvox USB DA design identicalI had a chance to listen to a Aqvox USB DA and take it apart. Talked with the salesman and he said both Aqvox and CEC licensed the design from another company. Like Borat said, take a look at the internals and compare for yourself. Identical except for the layout.
Only 2 different functions...really minor.
1. Aqvox added 0/180 phase switches, CEC does not. Ummm, if you really want you can just swap your RCA on the CEC.
2. CEC can oversample 1x (44/48/bypass), 2x (96), and 4x (192) where Aqvox is only 1x (44/48/bypass) and 4x (192).
Aqvox has headphone vol. knob, mic. switch, and sample rate indicator, CEC does not.
Aqvox uses a locking XLR on AES/EBU, CEC does not.
Aqvox USB DA cost around $630, and CEC around $530 for me in Asia.
Oh, both do "resample" to 195 kHz (line 8 in Aqvox's fact list).
I like CEC's design, smaller footprint, and lower cost. Dislike the 1 knob control. Obviously I like the direct button control on the Aqvox but the fit and finish felt kinda cheap to me.
How often am I going to fiddle with the filter and switch oversampling? Not much. Can live with 1 knob on the CEC to control inputs....and save $100 too. Now, if I can just find somewhere local to buy one.
