for sure the readers would ask themself why..since it's not the very basic...and I would answer that the DSP is so funny thing but no audiophile at all!!!!the processor lay on the signal passage before the DAC.....better switch it off and work for a better hardware as LPF circuit!!!!
I found there an LPF circuit and a buffer stage ...around buffer stage are spottered some transistor adjusting the gain....mmmmmm .... too long travel for a little audio signal !
the operational on the pic above is vanished now!!!!!!!!!!!
|a new laser unit KSS240 was really very fickle ...and tired..........neded a swap for a new NKS240..but pls don't try to strike the player...don't try even to tip on it....it will skip the track soon!!! :-(|
|here they are the new dip-8 socket|
|aaah.....here they are the 4 1/8 resistors swapped for 4 1/4 metal film res.|
Fujicon TM for decoupling of the two operationals.............panasonic HQ as decoupling around DAC
...and a couple of nichicon muse FG in the output followed by 2 stunning carbon composite resistors!!
Now the sound is really amazing: open ...so detailed and dynamic...a pleasure for the ears!!!! ;-)))
another nice mod on a Sony Cdp :
