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

Erik: My preamp is a Thor TA-1000. Input impedance is 250kohm. The DAC is transformer coupled and these are the only sizeable caps so I imagine they are the signal caps... not sure if that is the same as "ouput" caps? My ignorance...

Why wouldn't the designer have used two smaller caps if that is a better approach? I try to be careful about second guessing genius designers. Unless one big cap would have been substantially cheaper. Thus DAC retaiked for $4500 15 yeas ago so I imagine he wasn't cutting too many corners... although musicaps aren't the best caps, so maybe one big cap was a cost consideration.
