Hey Lall,
Actually the transport issues were dealt with within a year of the Opus 21's introduction. (And the issue was that they were slightly noisy.)
However, I will admit that they do have a slight issue with their lasers lifespan though, as mine finally wore out after I'd owned it for five or six years, and I was the second owner, so I have no idea how long it actually lasted. (How long are lasers supposed to last?) Anyway, I dropped it off at Jeff Kalt's place in San Francisco, (I live about 50 miles away), and he fixed it quickly and VERY inexpensively). Again, dealing with Jeff Kalt is one of the best reasons for buying a Resolution Audio product.
FYI: Jeff is finally getting ready to introduce a new state of the art CD player, (as the Opus 21 has been out for 10-12 years now), which I am anxiously waiting to hear.
