Here is c/p of my e-mail to Steve, right after my auditioning:
As far as the sound goes. Offramp offers great low end extension, instruments are precisely placed in the space. The width and depth of soundstage is enormous. No fatigue over long term listening. It has a somewhat elevated low end or recessed mid/upper end. I can see why you preffer Mac mini to Macbook and your choise of SPDIF cable is also obvious. That semi rigid cable looked to me like 50Ohm RF cable I use to use for work but I haven't connected it to network analyzer to look at the impedance. I don't have AES/EBU cable and using generic XLR definitely affected the end result. So despite what measurements suggest I prefer the sound of SPDIF out.
As far as comparing it to Diverter HR. I've tried number of SPDIF, USB and power cables. Also Offramp favored ACME slvr cryo outlet vs Hubell. I have furutech GTX-D on power amps and Hubell on DAC. The best way to describe it is to use analogy. When I listen to Offramp 5 I am in recording studio. I can hear all instruments without being combined into sonic mess. I can easily follow each instrument, though Offramp seems to highlight leading instruments/voices. Diverter HR offers something that I have never heard with any other transport. It replaces speakers with music instruments. It offers acoustical density that is very close to real life performance. I need some time to analyze what I have heard to pick the right words. When I listen to Offramp I want to hold my breath to hear more details. With Diverter my feet start to tap with music.
I only tried 2 different power cords with Hynes PSU, I am sure more performance can be squeezed from Offramp. Also my speaker placement and component selection were voiced with Diverter HR, so this will contribute to the end result.
These comments apply to my initial setup, Offramp on the top of Paul's PSU with vibration control tweaks in place. Now after I've sent that e-mail to Steve I've tried relocating Offramp with PSU and USB short block. I've moved Diverter HR and Offramp setup to one shelf. The low end emphasis (darkness as some reported in other reviews) has completely vanished on Offramp. Steve's BNC cable seems to emphasize midrange and highs in my system, a bit too much for my taste though it makes a great combo with Offramp 5 depending on component placement.
I wanted to thank Steve for giving me the opportunity to audition this top notch converter.
