I'm listening to a Jolida CD100A as I right this. I've had mine now for almost five years, and still use the OEM tubes. Have several pairs of new tubes to try, but just have not had the time to swap them out.
This unit seems tobe a little cable sensitive, and a good cable will make a world of difference with it. I use a Zu cable that's built for digital music (don't ask me what it is, as my memory bank is short). The player sounds really nice with 24/96 mixed cd's, but most are the usual 16 bit masters. I do have many 20 bit cd's though, and you can hear the difference.
In the same system there is a Marantz 8260 that I've came to love. But after listening to it for about a year now I think I like redbook from the Jolida slightly better. Seems to be a little less edgy (but this maybe the listener or once again the cables I use with the Marantz).
In my bedroom system I use a Cal Delta (it's got a lot of age on it) feeding a "half nelson" MSB DAC. I have about $600 in the whole shabang. Have gave some serious thought to buying a better DAC, but have not made the move yet.
The sound from it is similar to the Jolida, but maybe slightly better bass. The only real way to tell would be to put it in the downstairs system to compare, and I'm too danged lazy.
