Antique Radio Supply has the superior 716 P {copper leads and True film instead of metallized film} ... 10 for 22 dollars and change {shipping included}
I would take THOSE orange drops over the WIMA MKP anyday.
However, WIMA, ERO/VISHAY MKC capacitors {Polycarbonate, 8 for 20 USD shipped on fleabay} have better detail and are smoother
Of course caps are like spices, The REAL game changers are circuit topology and implementation... ie out put transformers, power supply...
