First post, newbie, audiophile/snob wannabee. Story - I have a second place where some lightly-used Tannoy Precision 6.2 speakers await that I now need an A/V system for. I'm stuck between cascading stuff from the main place to it, or buying something new for it. The main place has a NAD T787 (factory refurbished) and a 5.1 populated with Golden Ear speakers (I've been very happy with Golden Ear!). I've made believe thus far that NAD was the way to go ALTHOUGH I had to return the first T787 due to problems, the second had to go in for repairs in yr 3, and the second now won't retain some of the speaker setup selections. I'm terrified to do the factory reset fearing that it will be the death of it (advice on that, like don't risk it?). Luckily I can redo the settings in about 5 seconds using my phone EVERY TIME I power up. Was toying with getting a T778 and cascading the T787 to the other place but the T778 seems to have even more serious reliability issues. In that second place I did take delivery of a NAD T777v3 (factory refurbished) but the front display did not work - sent it back. Have nothing there now. MAIN ISSUE - I really like using the BluOS ecosystem, streaming from Tidal, imagining that MQA is something. I have a BluOS Node 2i, Rotel amp, and some Elac speakers that join in in a neighboring room. But, I'm thinking that I need to move on from NAD. I need 2 reliable/quality A/V systems, not projects, I have enough projects. What streaming ecosystem do people like? Want IOS control for sure. Thanks!
