I'll agree with your dad, bluetooth has been a poor wireless system since day one. That's why I've kept my bluetooth audio investments modest. Hence the R2, the Status BT Transfer, JBL Tune 115 and Sony SRS-XB43 are my current dips into the pool to determine if bluetooth audio is ready for prime time. I'll admit it's definitely getting better and I do like having a speaker I can place beside the bathtub. Each year I toss a few bucks towards bluetooth audio waiting for the day it's worth investing in better kit. So far wired is still far ahead of the game (if you care about audio quality).
I've got the R2 playing albums now but it's bluetooth implementation barely functions. Maybe I got a lemon and and the antenna in mine is defective; I don't know. I think it's a disappointing DAP in a variety of ways but the dysfunctional bluetooth functionality (the reason I bought it) is the final nail in the coffin. I wish I'd bought another Fiio or Ibasso instead.
