I'm using the Monarchy M24 now and have also recently put in Siemens NOS goldpin tubes (after about 3 weeks of the stock Sylvania tubes). This DAC has surprised me and may stay in my system. I have not tried the linestage and probably won't as running it through my passive preamp is working well at this time.
While I find the build quality to be very good overall, I think the push buttons on the front have a cheezy feel to them. I also leave the blue light that illuminates the sampling rate off. The sound on the top end still appears to be ever so grainy and bright, especially versus my non-os DAC, but the Monarchy does quite a bit more things right that outweigh this very minor detail.
