Price to peformance you are looking at the basic MKP types ... Solen, Mundorf, Axon, Erse, Dayton, Jantzen, Audyn ... Im sure there are others. It's difficult to find fancier constuction and "boutique" caps at the high, 100uf value anyway. And those that are available jump in price signifigantly as well as jump in size. The caps mentioned are quite large for the location that they are typically installed in Crack. Some brands larger than others. Higher voltage rating versions of the same cap are larger. Most are probably available starting at 250 volts (or higher). 160 Volts is the stock electrolytic cap ratings. Any of the film caps rated there or higher should work fine. If you can find out what is available, you can check on the size to make sure they will fit. All the caps I considered would have fit but didnt look closely at the size specs of all of them. The Mundorfs are a popular choice as are the Solens and Axon. The Axon is available at 91uf as opposed to 100uf but reports are they sound fine. Im sure that any would provide some degree of improvement over the stock electrolytics. I personally went with the 250 volt Mundorfs. It was a noticeable improvement. Not quite the impact of Speedball but worthwhile to be sure.
