I prefer film or PET caps for small values in the signal path, Polystyrene 1st choice polyprop (loads to choose from ) PET very good I like some of the old ERO 1837 radial or 1839 axial and the 1822 are also good I have them in my pre amp ATM, all made by Vishay now.
For electrolytics in the signal path I also like Elna Silmic2 and Nichicon Muze KZ, the Nichicon fine Gold are also very nice for everything else in the audio boards and KX/ KG for power supplies . Panasonic FM are also good and come in higher voltages
Mil Spec Wet tantalum are also very good in certain positions like feed back cap (I dont like solid tants in audio path though they are hard and grainy)
Panasonic FC are good for general controls circuits
For Bi-polar caps I like Nichicon ES
If you have to use ceramic caps anywhere use the COG types as the have much less noise
Hifi Collective or mouser have good stocks of caps
