Multiloop and inverting configuration
I have corrected the original circuit, hope have this right. Inner loops provide local feedback to the inverting opamp, two inverting opamps provide positive global feedback. Any comments?- martioz

Multiloop and inverting configuration
Is this a correct implementation of the multi-loop feedback into inverting Op amplifier buffered circuit? Hence inverting input has lower distortion I’m trying to configure feedback loop and overall gain. Any comment is more than welcome.- martioz

Mint-Tin Gilmore thread
To feet "full size" KG into mint box you need to go into SMT, but in this case you still need kind of energy source like batt pack or unregulated "wall-bug". I would vote for the external battery pack since is easy to control and gives you more flexibility (main is not really portable). To...- martioz

Considering the quality of sound, SlimX(2 - never owned original) is only average compare with "straight" PCDP. I like better D-EJ01, 915 and many of the old players. Through META and HD600 I can hear distortion in high and low freq spectrum. This player however is currently most features...- martioz

What's wrong with using solid-core conductors?
Solid core is better for both IC and speaker cables, IC as thin as possible, low diameter reduces skin effect. For speaker cable best would be fine ribbons run side by side not in parallel- martioz
