@bobheinatz Unless I'm reading your original post wrong, it seems you love the sound of your system now. So why bother spending another 10k - 15k on cables that don't seem to need replacing. The simple fact they are old is not a good reason, unless you just want to spend a lot of money? Take a nice vacation. Make some memories. So many other ways to spend your retirement funds. IMHO At the very least, make sure everything can be returned if you find the improvement in sound is not there.
Choosing new cables
I am looking to upgrade my current cables. This should be my last system as I retired a few years ago and most of my components have been seriously updated in the last couple of years. I have been in this audio hobby for about 50 years and have always have great sounding musical systems.
My current cables all work and sound great but are 15 - 20 years old. So updating is what I need. I am budgeting around $10k - $15k for all new cables.
I have always felt the i/c's were the most important cable followed by the speaker cables and the power cords. However I am now leaning towards spending more on the power cords followed by the speaker cables and last the i/c.
I know all cables are very important but how would you prioritize the cables? Any suggestions on any brands would also be appreciated!
