Any suggestions about how to modify it?

change some of the cap, in case u r planning to change cap for power supply, then use multiple cap instead of single cap. If not mistaken there are a few 2200uf cap there.
If possible you can use 10pcs of 220uf to replace it or 5 pcs of 470uf(if can't afford BG, BC, elna or nichicon is ok lah)
for OPAMP- a cheaper replacement can be AD825.
As i found the Lite DAC-AH is too emphasis on mid frequency...if use AD 825 it may make it more balance and better detail.
Next u may add a tube buffer if u like tube sound.作者: SSWONG 時間: 2008-7-11 10:34
Attached a photo of a heavy modded DAC-AH done by one of our member here. Anyway if i rather get a 1541a DAC if spend so much to modified a DAC-AH.
Attached is a power supply part of 1 of the 1541A, my friend is using this DAC... sound good.
