I've recently upgraded my amp and speakers to Arcam's A19 and B&W's 606 respectively to partner my Arcam CD73, which I've had for donkeys years. I've also upgraded the speaker cables and interconnects to Chord's Clearway. I'm enjoying the fuller, more open sound immensely. I'm now thinking I should upgrade my CD player, just to eek out that final bit of detail that I can just about hear is there in the mix, but not quite realised. There are plenty of CD17s available second hand and not as many CD37s for a sensible price. I don't think I'll be playing SACDs, so I'm wondering if a CD37 is worth holding out for? Is the CD playback sound between the two models any different? Is the SACD functionality the only real difference between the two and CD playback-wise they're fundamentally the same? I'd be interested to hear your thoughts. Many thanks.
