I use a pair of DSP33s fed by a USB to SPDIF converter (see my Office system in my signature below).

The controller (necessary with DSP33s as they have no IR detector) is a 565 which I had lying about. This limits the throughput to 48k. An alternative would be a 562 which may pass 96k (never tried) and not enforce that limit as it only switches and doesn't process. The USB to SPDIF could feed the DSP33s directly and I could just use the 565 for comms/volume control - never tried it but it should work; this would also allow 96k.

The speakers (second hand) worked straight out of the box with no config - perhaps I was lucky? They are insightful, musical, they image brilliantly and give the facsimile of excellent bass. They sit on the large solid desk top against a wall and have rubber bumpons fitted.

I believe that the DSP3200s would need a controller too so they would not work with just an SPDIF to Speakerlink adaptor from a USB to SPDIF device. Happy to be corrected.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
