I put a LUMIN D1 in my system 4 years ago and I have not looked back. I get automatic upgrades from LUMIN - this included MQA when it came out on Tidal. My LUMIN D1 cost $2,000 when I bought it. It interfaces well via my I pad mini. Tidal music files are great - the MQA files are amazing - it has been trouble free. You need to feed via an Ethernet cable, and I can feed out to both of my systems in the house ( balanced and unbalanced). This eliminated the need for my turntable and CD player in my system. I run Magnepans (1.7s with the bass panel) that are bi amped via Krell and Ampzilla. I am hearing stuff that I have never heard before. Great soundstage, great high end, great resolution. Buy a LUMIN - they have great support and the unit is bulletproof.
