Default mods for Adcom GFA 555 II

what would be good mods for adcom GFA 555 mkII? i am looking for detailed instructions, like "replace capacitor of make A and capacitance X with capacitor of brand B with value Z". )
i am new to this diy stuff, but i am getting some help from a hardware engineer, so i should be ok. ) i want to improve the mids and highs. someone told me that i should replace capacitors with Blackgate caps and resistors with Vishay ones, but i am curious about the values for capacitance/resistance. should they be the same as in the stock amp? basicaly, the more details the better. i looked at other threads, but could not find any detailed explanations of mods. any help is appreciated. thanx!

You still wasting peoples' time on this?

How did you make out on the power supply bypass caps?

What changes in the sound did you notice?
