@lanx0003 The ICON being compared to a reference level system of that cost/caliber is ridiculous.
I had one for a couple of weeks. While I think it is a good one box solution for the money, the $6K Lumin T3X I ended up with completely blew it away. Not even close. No surprise either, obviously. But, if the NANO is close to the ICON, that's a real bargain for someone entering Hi-Fi/streaming.
Now on to the OP's question (yet another survey): Roger's High-Fidelity EHF-200 Mk2. Crap amp, and worse Company.
Getting rid of the Roger's and ending up with my T+A integrated was one of the happiest moments in my short "audiophile" journey.
