Yeah, I’ve looked at the L&P product line and while really, really cool, they’re also really, really, really expensive. And between the fact that they fill both digital source & dac roles and the speed at which digital source technology is changing (bluetooth codecs, versions, etc.), I just haven’t been able to justify the price. I’ve also looked at the HiFiMan R2R2000/HM1000 and I feel that has the same fundamental issues. I also have concerns (as a software engineer) about the longevity of custom OSes like those used on these devices. They’re so close to what I’m looking for, but at the price I don’t think I can really justify their cost.
That being said, I’ve already pre-ordered the Cayin C9 
and I think I can get by with that and my BTR5 or C5S until someone comes out with more ideal kit for what I’m looking for.
