a lucky tuning in a Denon DCD-725
Analog devices opamp AD8058 fit very well in its LPF out !
I found out these Marconi's cup that shock me for their very balanced midrangeand their neutrality overall......very refined indeed!!!!!!
 |
| ....new power supply capacitor filter do the rest of the job |
|
 |
| ....the job doesn't go so smooth ....one of the opamp was prone to oscillate in this circuit probably for the low filtering of supply so here you are another tuning |
 |
| ....finally a couple of cap between the pin supply of opamps to smoothering oscillations |
 |
| ....the game is done!!!!!Now it sounds very very good!!!! |
