What is the best replacement upgrade?

You might be able to fit some Panasonic TS-ED's on the board, just be mindful of the case diameter.

Film caps!
The stock electrolytics are quite good. But film caps can have even lower effective series resistance. But they are physically huge at 220 uF and 600v. You can use a choke in place of a resistor between the caps (clc instead of crc) to lower ripple enough that smaller (lower capacitance)caps make sense.
Having done this, I can say it sounds better to me than stock, but not by a great deal. It's subtle, and not the first place I'd spend my fancy cap money.

Film caps are tough in a doubler supply, as those first stage caps need to be pretty beefy to keep the ripple reasonable.

I like Nichicon's - here's my yet to be implemented power supply board:

I sure hope I have them installed with correct polarity! I really like the document where there is an entire page or two or three dedicated to "GO BACK AND CHECK!!".

Yeah, the Nichicons are another good suggestion, and fairly available too. I'd recommend modeling the power supply to triple check that the ripple current isn't too much for whatever is chosen.
