Bypass cap recommendation

[Jimb0]

What do you guys think of bypass caps on the stock output caps? Do you guys have any recommendations? Thanks in advance

I have 2 Cracks, one with Panasonic output caps (square ones) and the other with Daytons. Both amps do not have bypass caps and I have read that bypass caps may do more harm than good with modern film capacitors and that is the reason I have not bothered. Both amps are fabulous. There are very affordable caps to try and I may some day but I haven't been convinced so far from the research I have done.
