IROC DAC or PS Audio Ultra DAC / Digital lens


I am exploring DAC's for My Mini Mac computer based music server the PS Audio Ultra DAC / Digital Lens and Larry Moore and his IROC . These are the two products that look most interesting to Me as of now . I was wondering if any people who went to RMAF had a chance to hear both of them and any thoughts.I did have a chance to hear the IROC once at a Cincinnati audio club meeting but this was before I set up My own music server. I would be using either optical [ Toslink } or USB out of the Mini Mac I just copy CD'S to My hard drive in AIFF and have no Hi Res downloads just looking for very good sound.I may in the future want the ability to do Hi Res files 24/96 but that is down the road a little bit I am still learning all this upsampling /oversampling /24/96 / 24/192 ect. just trying to figure it all out. I now use a older Cal alpha DAC with 24/96 upgrade and a Toslink cable sounds good but know there are better DAC'S out there. Thanks for any thoughts Marc

My $.02; go cheap and/or used for right now and wait for the consensus to develop around some of the newer products and technologies.

PS Audio's new Ultra DAC has the potential to be a game changer with it's ability to handle any and all resolutions and it's use of I2S interface. If I remember correctly, they said it would be around $2,000 at the RMAF. I listened to the MusicStream at the show too, but the room was so overwhelming I couldn't give a good evaluation of it (trying to show off the Dodd amps and LS9 monster speakers, they had the volume way too loud).

My favorite USB DAC of the show by far was the asynchronous Cosecant by Wavelength. It sounded practically jitter free and I just melted into the chair listening to it. I could have stayed for hours. The price tag is about the same as teh MusicStream (~~$3,500 U.S.).

For the record, I currently have a PS Audio DAC 3 with the Cullen Circuts Level 3 mod. A nice unit and great 'bang for the buck' ($1,000 plus $600 mod), but not on par with the three above.
