I bought the converter to my CD collection on hard drive to preserve and then to listen via laptop, since twice the laser unit had to be replaced in my CD player. To my system, AV Rceiver Pioneer VSX-921-K and speaker Onkyo SC 901 (peaks speakers from the 80s), DVD Recorder DMR-EH52.Anfangs I found the sound in comparison to the DVD recorder very good, above all was the noise nearly inaudible. But then I put on a CD of digitally recorded gun salutes. Normal a Masage for the stomach. But here, nothing, on the contrary properly Blass no bass. Now, the CD's out with ansbruchsvolleren recordings. Was Fatzit than better sound card, it evaluates the laptop on but against the original (CD) no chance. Why this device is blessed to some HiFi magazines so no idea. For me, it has failed as a replacement CD.
