All but the Bluetooth adapter gotten used/demo from this and the other site. What a great way to shop! Everything came in great shape and works well. This is my second pair of MA speakers and I've been delighted both times. I know lots of folks are into vinyl and tubes, but as an elderly man I remember all too well the pops and crackles of vinyl and the frequently crashing tubes. I'm happy with this and only look forward to getting a solid streamer. To paraphrase the Talmud--Who has the best system? the person who is happy with what he has!
