“Please put me down for your next HiFi invention; whatever it is, I want one!”

“I received the D.BOB yesterday, it was very simple to hook up and worked perfectly!

I can now get far superior sound quality using my DirectStream DAC rather than the inbuilt Sony unit. This is a far better option than investing in a very expensive SACD player that doesn’t have all the functions of the Sony when used as a DVD player”


I Pounced (submitted to Kal Rubinson on Stereophile website)

“Hi Kal, I decided it was time to upgrade my Ayre C-5xe and purchased the D.BOB from Eric Geer in January. There was no way to buy it in Australia, I had tried online. Eric was extremely helpful even though he was attending NAMM at the time. I use it with a Chord Hugo TT2 and Cambridge Audio CX-UHD transport. The Chord TT2 accepts DSD via DoP on S/PDIF. I have also used it with a Chord Qutest. It has worked flawlessly and I’m completely happy with the D.BOB”
