Already have a set of Nichicon on the way but now I'm looking at other caps.
If it's a simple swap and change until I get the sound I'm after, I might just grab some other bits and pieces to test.
I can see this quickly becoming a slippery slope...
No, voltage in this kind of coupling application is only at most the initial voltage differential when connecting up (say, the voltage rail at 16V) and quickly becomes tiny.
Well....Quote:

All 47uF as I honestly don't want to go playing with the capacitance until I know why it's a specific number and what changing it does :)
As I remember, the Nichicon MUSE sounded best but Rubicons were also good. I never tried Elna Cerafine bipolars but if you look at my photo you will see that I replaced all the polar electrolytics with Elna Cerafine II caps and this made quite a difference to sound quality for a small outlay.
The capacitor forms a high pass filter with the input impedance of the following amp stage. go too small and the roll off may affect bass subjectively, 47uF is more than enough!Quote:

So I stole some 47uF caps from the opamp board because I just couldn't wait.
I'm new to audio lingo so please bear with me.
I'm noticing some sibilance in certain vocals and also female vocals appear a bit dull or lacklustre. I'm also getting some pops when switching between tracks, but this could be my source. It's also a lot brighter than before.
What I have noticed is that the instruments seem a lot more separated and defined, I guess this is what is referred to as sound stage.
The bass is also a lot more defined but seems to be lacking the depth that it was before, I'm unsure if this is actually due to less bass or due to it being a lot brighter.
I'm looking forward to my other caps arriving, I do like how it sounds bar a few small issues.
I take it I'm not the first person to run kit with the case removed. :)
I'm also finding the vocals slightly lacking a presence, not sure if this is just the caps or I'm listening for things that don't please me :(
Give each cap set a few days to settle, Jim. They take time to open up. However, your observations about bass tightening up and perhaps appearing less powerful match mine. I don't remember midrange (vocals) lacking presence, though. That sounds like new or poor caps, I think.
