OC1

Grimm Audio OC1

Originally built on demand for a few AD1 customers the OC1 solves an important interfacing task. Though SDIF3 is the only official standard for DSD signal transport, Sony got the demand from some customers to run multichannel audio over larger distances on a single cable. Their solution was the ST optical format, developed for (then Sony) Sonoma and emmLabs.

“The OC1 converts the AD1’s SDIF3 format to the ST optical DSD format.”

Grimm Audio’s OC1 converts the AD1 SDIF3 format to Sony’s ST optical DSD format. It is part of our line of little ‘problem solver’ boxes, build in rugged cases but lacking our characteristic wooden front.

A fantastic experience to work with this device.

I'm now using a DSD converter called a GRIMM for my SACD mastering. Big improvement.

Among all the truly excellent SACDs from Channel Classics, the very best sound quality wise is the Mahler 4th recorded with the Grimm in my opinion.

Grimm products have that typically Dutch sound character that I love: warm but clear.

The sound of Grimm recorded SACD's is AMAZING, it totally closes the gap between analog and digital.

I have used all high end AD converters known to date. Every one of them had a sound to it. Your converter doesn't: it is completely transparent!
