Purist Audio Design Digital Isolation Adapter

Purist Audio design is proud to release a solution for impedance control between equipment with electrical isolation of the digital signal.

The adapter is designed to:

  • Help isolate the digital signal from the transport to the D/A
  • Reduce jitter by impedance control
  • Reduce EMI/RF noise


The adapter can either be plugged into the SPDIF (RCA) output of a CD Transport, or the SPDIF (RCA) Input of a D/A. Connect the SPDIF (RCA) Digital cable into the adapter and equipment.

Through our testing and usage, we have found that using the adapter on the D/A's SPDIF (RCA) input yields the most correction.

Purist Audio Design adaptors use only the highest-quality metals: copper, silver, gold, even special alloys. They are fabricated in a single rigid construction, maintaining the integrity of the connection and avoiding sound degradation.

Customer Comment:

Well, I had to stop the presses. It corrects time. I thought I would try the new Purist Audio Digital Isolation Adapter quickly with my headphone set up first. It was late at night and I was thinking why not. What will it do? What can it do...?..should I remember the music...what to expect? I mean it already is sounding very good.

So.the first music (Dianna Krall ...One Quiet Temptation).shocking...I did not expect an instant 10.The breath...the light percussion. It slows down the song to a pace that is studio live...and the detail is breath and the notes slowly decay with the right harmonics...yet slow and effort. Need to say...Im keeping is quiet..but not overly is time and space.

Please tell Jim...this device not only isolates correctly places you in the time zone...voices are seamless with the percussion and bass...and the timing of the vocals breath allows you to feel the time....all members of the band are one experience in time...there is no listen here or there.

All is one. And one is all.

So happy...please share allows a palpable experience...when a song ends you are allowed to feels the ending...piano pedal release....and then stop. I will have to try on my main system..or get another one. Your products never disappoint!
