I too have the Cal Icon II (non-HDCD) and have been interested in a cost-effective upgrade. My own research has led me to the new Jolida 100 CDP, but I've never heard one myself yet. I have listened to a few other lower-cost CD players but none have been as good as the Icon so I've held off. I hope to hear the Jolida soon. You can get one for under $800. It seems that I would have to spend at least $2000 to get a used player that would sound better to me than the Cal. Perhaps, like you, I should just stay where I am. FYI, I bought a Sigma II DAC but have not been able to discern a big difference with the Icon. I changed the tube to a NOS Mullard, but still don't think there's much of a change. The Icon is a great player, don't sell it, keep it as a spare!
