I will be looking towards 4700uf, 35v, for use in both my DAC, and preamp/headphone amplifier.
If they are even close to say, Nichicon KG, then they are a bargain, given the long, rated lifetime. Who knows, may well be much better.
The bass - junkie, portion of my brain has me hesitating...

Have a problem because I bought som exspensive regulators fitted with Panasonic FM 4 x 1000 uf 100 v on each. I am in a dilema. Shall I use them or trow them in the trash and buy some new ones. 1000 uf 100 V 18 mm x 40 mm is hard to get.
How to make a "fast" charge/discharge with a very good low-end?
Let's say the original power cap is a 12000uF 63V per rail. A couple of two 6800uF RIFAs would be great...
that's +-825uF/channel
typical Power Amplifier smoothing is from +-4700uF to +-40,000uF per channel.
If one uses only +-826uF, then expect no bass performance.
BTW, 100uF to 2200uF is typical of MF decoupling. 250 off 3u3F is MF decoupling, if you can locate it close enough to the power pins of the output devices.
No Rubycons anymore?
Haven't heard about Rubycon caps for a long time here.
Is it loosing market? Out of audio-grade sector?

An externally hosted image should be here but it was not working when we last tested it.
I hope they haven't crossed the Rubicon to a fiscal downfall or something.
I like the ZL and ZLH for their durability, size and low ESR - they're fine for SMPS/PSU/VRM applications, as well as general digital bypass on PC motherboards, etc. YMMV for audio duty - ZL is good for bypass, but probably too harsh in most signal-path applications. Almost all Rubycons (except Black Gates) have magnetic leads.
Similarly, almost all Nichicons (except some Muse series) have magnetic leads. The Muses (especially KZ) are great for just about any audio application, but physically large. Muse KW and SW are good trade-offs - relatively compact, and reasonably good for audio.
Rubycon got into trouble because they were late in switching from Aluminium to Solid Polymer Electrolytics, which are now the mainstay of the commodity PC and digital equipment business. That business is now dominated by Sanyo, Nippon-Chemicon, Nichicon, and some Chinese and Taiwanese rivals. They also got killed in generic electrolytics by Panasonic, Elna, Nippon-Chemicon, Samxon, Samwha and others. Rubycon now has some polymer lines - but probably too little, too late.
It doesn't help that they also stopped manufacturing their niche high-value lines like Black Gates.
