Sorry to say it, but I think Ray missed the mark with The Intruder. As far as I can tell, it's a more powerful SR-71B (which arguably wasn't necessary, as I wouldn't expect enough people are likely to either travel with top-of-the-line over-the-ear headphones or drive them at home via a portable amp) with a DAC incapable of supporting audiophile-quality files. Hopefully, the arms race is over now that any headphone can be capably driven from a portable amp such as The Intruder or Rx MK3-B. Me, personally, I'd prefer an IEM-focused, cost-no-object DAC/amp that does it all or a purpose-built amp with no glaring short-comings.
If the rumors of Ray's stand-alone DAC are accurate, despite it being 24-bit/192 kHz, I'm concerned that the mark is being missed again. Based on all of the buzz, it seems Ray would do well to target something like the Centrance HiFi M8 which, in my view, will have all of the key boxes (DAC plus amp in one, 24/192 support, Apple device compatible, USB compatible, etc.) checked. If not an all-in-one, at least target the other three.
