Hmmm... I would say clocking issue is probably likely, but listening to it, it doesn't sound quite like the "tickticktick"-ing that I would expect. I can't really offer an alternative diagnosis, though. I can, however, offer to transfer the remaining discs you have using an RH1 and provide you with the original ATRAC files. Which, while I realize it's pedantic to discuss lossy transfers of a lossy recording format, is the preferred method of transfer; ATRAC is a floating point format and one could argue that converting to a fixed point format will introduce losses, especially without applying dither. ATRAC can be played back directly in VLC and converted to anything else using FFmpeg, fixed or floating. Back when I was doing my transfers I figured out that converting to floating point wav and then compressing with WavPack was one method to maintain floating, as FLAC only does fixed. Somewhat moot, since you can just archive the original ATRAC file, anyway.
