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 ?

Funny, I'm a PWD (I and then II) owner who is very sensitive to edge in the highs, and I've not been tempted to call it "treble heavy." Actually, "relaxed" comes to mind first. I wonder if Steve is right and the issue is somewhere in the system.

The MKII upgrade will resolve all your issues. It makes the original DAC a whole new DAC altogether...Read the recent TAS review...

I have to agree with John (Jdoris). I had the PWD in Mk.I form before upgrading to Mk.II, and in neither case would I call it treble heavy. Relaxed but highly resolving (referring to the Mk.II).

'Treble heavy" emphasis and higher or improved resolution are`nt the same. True resolution improvement is desirable.Heavy treble is an unwanted coloration.The MK II upgrade seems the direction to go.

the only time i've felt it was treble heavy/bright was when using 100% silver core ic's (acoustic zen silver ref 1 & 2 to be specific). not sure why?? as others use silver core ic's with the pwd and have different feeling/results.

what type of ic's are you using and have you tired different types??

agree with others who say the mk2 changes the game. more resolution but smoother in every way. great upgrade i highly recommend.
