The biggest quandary for me is, knowing that I can get a refurbed CD Pro 2 like the one in my AA drive from ENCO, is the CD Pro 8 that much better to justify the 20x cost to get the Aqua. I do expect it will sound better but <$500 also sounds pretty good compared to approx. $9000
When you put it in those terms I understand your dilemma. Certainly the discontinued Philips CD Pro 2 is a CD drive unit that has stood the test of time and was utilized in numerous top shelf transports. You have enjoyed its quality for 20 years so obviously you know its capabilities.
On the other hand I don’t believe it is a coincidence that The Stream Unlimited CD PRO-8 has been chosen by top level manufacturers for their upper tier CD transports. If budget is a major criteria then certainly a refurbished Phillips CD is very viable and prudent.
