Its worth trying Hamish, its possible it may not suit your set up but if it does you may be surprised . Its really something you have to try in your own system to know if it works well for you or not

Which caps do I ask jimmy for, and could I get a clearer photo of exactly how to slot them into these holes... Which holes and which way... That will give me a clue if it works for me eh
Hamish - if you use bipolars then you don't have to worry about direction. You could do a lot worse than a pair of Rubycon CE or Nichicon Muse bipolars.
Remove the op-amp board, taking care to cut the gunk holding it down to the main board. Then fit a cap to the top two holes and another to the bottom two holes of the left socket, leaving the centre hole empty.
Take care to mute or set the volume to minimum when you start running music, then you'll be ok once the charge on the caps is constant. Leave at least 48 hours before starting to listen seriously. That's 48 hours of music, not standing idle. You can leave the amp turned off.
This way, you've done no damage to the Caiman and can put it back the way it was at any time.
I would suggest you "turn them mostly clockwise".Quote:

Yes and yes. Although 6.3V caps will also be fine as no more than 2.5V will ever go through them. :)Quote:

I've got the following caps on order:
Mungdorf 47uf 35VAC-100VDC MLytic Bi-Polar AL (BR100-Raw)
Mundorf M-CAP RXF 22uf 350V
Mungdorf M-CAP MKP 15uF 250V
AXON 47uF 250VDC True Cap
Nichicon ES 47uf / 6.3v
Blackgate FK 47uf 16v
Panasonic FC 47uF 10V
ARD(ROD) 47uF 35V bipolar (from RS)
I'll also try and get some of the Rubycon bipolar caps from Tirna.
Its going to take me ages to run all these in and compare them but I'll try to post a little review asap. :)
Anything between 10uF and 47uF will do, but 10uF will be more suited for rooms that suffer from too much vibrations with your current speakers. 47uF would suit subwoofer owners. I am quite happy with 33uF, but they are not as common as the 47uF. So some people sell them for more than the 47uF.
Not sure if the high voltage caps will suit.They don't seem to work well at low voltages.
