I have a Lite DAC-AH for about 2 years.
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.
