The Off-ramp employs the M2Tech asynchronous driver. I use JRMC to ouput bit transparent audio in WASAPI. I compared the AES with S/PDIF and discovered that the S/PDIF sounded a little better. The Off-Ramp V4 with Ultraclock is not a subtle upgrade in my system. The soundstage is wider and deaper. I no longer hear the high frequency harshness I heard with the Lynx or the Wavelink. The sound is relaxed, natural and analogue. It is also fun to turn on the Monolith battery PSU while listening to music to hear the difference that it makes. I have been using a Lynx AES 16 and have tried the Wavelink in same system. The upgrade in resolution is so great, it's unnecessary to compare with the Lynx like I did between the Lynx and Wavelink.
