Interesting handle.
Creek CD player - you have taste sir.
What Opamps are currently fitted?
How many are there and what position in the circuit are they beig used? (image of circuit board at reasonable res would help).
Burson replacements for the run of the mill opamps are indeed a great replacement, they are well constructed and supported. An alternative is to be found at the audioguild website, you will find they have available 3 different descrete opamp replacements, they tag these earth moon and sun which is supposed to describe the sound, they are better priced inc postage and I have tried these and they are indeed good
You'll find that replacing the output caps can make a huge difference too and I would point you to the excellent POOGE articles from the US audio mags.
With a specialist manufacturer like Creek the player would have been 'voiced' so you need to understand that you can upset the balance easily. The usual suspects such as AD845's OPA 41's and many others are available for their 'sound', each of the descrete offerings transcend these by a fair margin IMV but you'll need to tune the circuit around them by looking at the power supply decouplers and voltage regs. There is a huge swathe of information surrounding opamp replacements which a simple google search will unearth. If the PCb has socketed opamps then its very easy to change them, if however they are soldered and the PCB is a multi sandwiched afari then its a different matter all together and novices should stear well clear as you'll end up overheating the pcb and lift tracks, if you don't know what this is - be warned you could end up with a very dead CD payer.
Burson have a good how to video on their site which is worth a look.
What's the rest of the system?
