to those who are building this dac..
i have change the 28 pcs decoupling caps to 0.47uf BG NX-HiQ ..
much lower noise and deep deep bass!! very worth upgrade!! recommanded!
Great to see you upgrade your 1541 dac. Except the Black gates and double 1541, did you made any change to the original circuit you sent me earlier? Are you still using the 5687 as the output tube?
yup...im still using the SE 5687 output stage. but with better power supply..CLCL supply..much cleaner supply..music kinda slow down a bit..dont know why??)
