They are now giving a little more bass yes and the more I run them in the better they get.
And I must say how suprised I am by them, they are running in very quickly indeed, the sound is getting deeper and fuller with the tops being very tight.
Im running India Arie cd on repeat has this has loads of bass.

looking at other caps for the filter of this buffer
polypropylene
http://au.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=106780&N=0
or
polystyrene
http://au.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=9520414
i've had experience with the polystyrene's
any comments about the polypropylene?
both are 1%
mica's are 1% also, these are cheaper for better matching

I bet that's a mistake. I didn't think polystyrene's were available in anything approaching 10uF! And the price doesn't match the expectation. It should be much more expensive. I think it's 10nF lol

Fancy that
using a non polar electrolytic as a coupling cap
What will i think of next?
allan
ps
is the bass tighter?
that was the problem with the fet's

Yes it is tighter and its getting tighter with use too.

farnel has them to 10nf
polystyrene's and polypropylene's
RS has the styrene not the propylene
Forget the matching mate. From my experience stereo balance is indifferent to a 2% mismatch.
Polystyrene is a good dielectric, much better than polyester.
In high values inductance starts to play a role. That's why I use bifilar wound 'audio' caps.
Take a google on Cardas and Auricap.

But the RON/RO LON/LO sections of the filter need to be as equal as possible.

Hey, made it to page 300 😀.
No, you can drop them right in.
Hey, that's a nice result Brent. Did you by any chance compare them to parallel-super-E-config BG N/NX types?
Regards,
Ray.

I ordered some BG N when I ordered the BG AC but they sent BG C instead of the N so they have gone back.
I will test the difference when the replacements come

No, the PWM-signals have to be subtracted (by the differential input stage in this case) to produce the desired output signal. See page 21 of the SM5872 datasheet. So it's nice to have two equal halves of the passive filter for each output 😀.
rowemeister said:
Hmmm, bummer. I'm curious what their sound will be like. Still haven't decided on my output caps yet...

Ray,
There's a slight misunderstanding going on as I wrote about the stereo balance being indifferent to a slight mismatch in coupling caps. Of cause filter components are to be as tight as possible, especially for the one following the DAC. Right?

understandable misunderstanding😀
as for the 1%
they are polypropylene not polyester.
cheaper for matching
if the BG's are out of production we are going to have to find something else

Oh, ok Jaap. But Allan was talking about the filter caps, which you replied to 😀.

Anyway,
I've tried all three of them, and I like silver-mica and polystyrene the best. In the filter that is
