toning down the ps audio perfect wave dac


i own an original ps audio perfect wave dac. i called ps audio about sending it back for an upgrade. a technician i spoke to said the upgrade would increase the resolution of the dac.

i would like to tone down the treble a bit, as i find it a bit treble heavy.

i thought the least expensive way of doing this is substituting caps in the signal path and or replacing the metal film resistors with reiken carbon fibers.

i am not familiar with the "sound" of caps, but would like to soften the treble.

the only caps i am aware that might do that are audio note, mundorf or duland. am i on the right track ?

if not, what other caps could i consider ?

when i substitute another digital source in place of the ps audio combo, the "hot treble" or thinness in the highs disappears. thus, i would think that the problem is either the transport, dac or both. i have a variety of cables. one is gold, one is copper and one is continuous cast silver, the neotech nei-1002. i find using the gold ic as a coax digital cable, with the mojo audio copper ic helps.

incidentally, as i said, it was the technician who suggested that i replace the caps and use carbon fiber resistors, and discouraged me from upgrading to level two, with either firmware choices.

there exist caps which can alter the spectral balance.

i should also note that one of my cd players is a better transport for 16 bit discs than the ps audio transport. my settings for the dac include filter 5 , coax and native 44.1 sampling rate.
