There isn't a thread, so I'm just going to post here for now, but I put a down payment on an interesting DAC. I will be getting a "DAC II Special" from the maker SW1X Audio Design in the UK. To say that I am excited is a massive understatement.
The creator, Slawa Roschkow, specializes in NOS R2R designs that are tube-rectified, tube output, no op-amps, minimal use of transistors. He also implements a USB to SPDIF converter with a tube master clock. The particular model I am getting also allows you to roll transistors in the I/U conversion stage. The only other person on Head-Fi I know of who owns one of Slawa's DACs is our host. Talking with Slawa, Glenn, as well as reading testimonials convinced me this is the right fit. I'll likely make a thread when it arrives, but it will be some time before it is completed.
