Audio Logic DAC cap rolling... replace 5.0 value with 4.7 ?

I just bought an Audio Logic 24MXL DAC. Really nice piece and sounds great. I may consider upgradng the two big caps which are Musicap 5.0 value. Some possible replacements come in 4.7 value and I wondered if they would not be advisable to use. Could this difference be enough to change the sound In a way the designer didn’t intend?
(Recognizing that different caps will do just that ... but lets ignore that part ;)

Thanks for thoughts

OH, one bit of advice I will give you, you'll be a little better off if you can split your caps.  That is, instead of using a single 5 uF use a pair of 2.4uF. It gets you closer to your ideal (4.8uF) but cuts inductance and ESR (equivalent series resistance) in half.

Probably won't help with Mundorf Supreme caps as they use this internally.

Best,

If these are output caps, no, either value will be nearly equivalent so long as you are going into a relatively high impedance preamp.

The bigger the cap, the lower the -3 dB of the output will be, but 2 uF is probably enough, 4 way overkill and 5 much more above that! :)

So, point is, going down a little from 5 to 4.7 should be fine, again, if it is the output DC blocking cap.
