I like Mr. Nixon's gear too. However, I need USB and optical inputs-sorry I should have been more clear.
I spoke to Scott about one with digital-in also. He said the design won’t allow for both I2S and optical. Scott said he just puts two DAC’s in the same chassis (one USB/I2S the other SPDIF) with a cost being about $1000 but in a nice metal case. He feels USB is superior for computer based audio. He makes a tube DAC with digital inputs too and they have interchangeable power supply’s.
I used a California Audio Labs 24/96 tube DAC with my PC for a while. I tried a few digital output devices, settled on an M-Audio DIO with a glass optical cable. I think the USB Scott Nixon sounds better and it was a lot cheaper.
Why do you want digital inputs too?
Hi boead,
I think computer based audio sources are poised to dominate. Soon, I think and hope, we will be able to alternate between music and movies from the same laptop/pc/remote hard drive source-at significant price v. performance advantages over our current CD spinners. Therefore, DACs accepting optical or coax digital and USB may well be useful for a long while. Secondly, I'm curious if a solid-modern-reasonably priced DAC will improve the output from my Cary CD-303 (5 yrs. old) and my Oppo DVD-970HD. The PS audio rig seems very well engineered plus it will accept almost any germane signal.
Thirdly, my McMormack MAP-1's ARM device derives 5.1 content from two channel sources (I do not use a center channel yielding 4.1). Anyway-I've tinkered with building a 2c music/multi-channel music/HT system for several years. A DAC with USB might help me a lot.
Thanks for your help and Merry Christmas if appropriate-Happy Holidays either way!
