Excellent DAC, I owned one for 5 years, and you can use any of the FPGA updates, as some prefer the older ones, though most prefer the last one...
Opinions on PS Audio Direct Stream DAC (Mk 1)
PS Audio is clearing out factory refurbished Direct Stream DACs, the original version from 2014 or 2015, for about $1800. I'm wondering if I could get opinions on this DAC. It's old technology as far as digital goes, but it got nice reviews when it was new. It can do DSD64 and DSD128. It upsamples everything internally to DSD.
I'm interested in musicality and musical involvement, especially dynamics (macro and micro), accuracy of instrumental timbre and extracting the beauty out of the recording, low noise floor and high resolution.
