Contrary to what I am used to, I have made very few musical examples simply because it is very dependent on the associated DAC. The modified Hiface is a very transparent device. It doesn’t have a sonic signature of its own. As far as I could tell, the overall sonic signature will depend more on the associated equipment and the recording itself than on the modified Hiface itself. For more details about musical examples, I invite you to read my review of the DAC19DSP for which I used the modified Hiface as a transport. (See here: Review of the Audio-gd DAC19DSP & C2 amp - The ACSS connection). While the modified version that jkeny sent me is still a prototype, I can say that it by far the best converter I have listened to in my system. I was expecting a small improvement (since I considered the stock one being excellent) but I was totally surprised by the level of performance of the modified Hiface. Its effect on the sound was not subtle at all. jkeny described the sound of the modified Hiface as similar to that of expensive analog and I couldn’t agree more: his modified Hiface make the other converters sound broken. Personally, I have already asked jkeny if I could send him my stock Hiface to have a similar mod done to it.
