I remember loving the sound of the Solo CD player, although I doubt it would really stand up to comparison with modern players. I’m not sure it was even 16 bit!
Not what you asked for (what else would you expect on here ) but this is a similar vintage (and French iirc) and looks interesting - pretty sure Mark @browellm used a Helios for a while?
I have a stage 2 i might be thinking of selling it is boxed but the remote is pretty dusty(not sure it will work looks like the batt were left in it) but the player is fine never really used it as i never took to cds although i still seem to have collected quite a lot of them…P.m me
