Using BT as it's easy to use and I got into BT much before WiFi and did not transition to WiFi.I do understand the audio quality limitations.After using Arcam miniblink the audio quality is good enough for me. BS was a good fit as I don't need to display and box size of CA.However it looks like the choices are fairly limited between the rs50k to rs1lac range.BS sits in sweet spot.From what I gather, Bluesound has the best OS among all, it’s actually it’s plus point. If you are keen on sound quality, then look beyond, unless you aren’t going to use its DAC. Arcam should be good. I am happy with Cambridge CXN. But they are costlier than BS. One can attach an antenna (to be purchased separately to CXN) for Bluetooth. But u. But I don’t undertand why you prefer inferior Bluetooth connection over Wifi?
