Old Amp vs. New Amp

At about 20 years old some amps will have capacitors that will need replacing, but that usually isn't too expensive or difficult. Tube amps obviously might need retubing at almost any age, but even if you just look at inflation and depreciation, the math quickly tells you that older amps can offer tremendous value. For the same money as new "entry level" amps you can be looking at older near SOTA amps that will perform at a much higher level. Cheers,

I would venture to guess that the used $5k amp would even surpass the P5 in capability and you would be set for a long while with the amp.

A cable conversation could take your whole life to read the history. There are some inexpensive ones that work great for many of us, but I'd suggest discussing that in another thread or by first looking at cables in some posted systems you like. Cheers,
