Nichicon Muse and Fine Gold, but these caps are discontinued recently and only stocked amounts left. Those white caps were not original, original are electrolytes. And Nichicon are the best audiophile caps available.
Hi, I think you have swapped a rechargeable battery for a cell battery non rechargeable, I don't see clearly on the video but if the original is a nm2032 then I'm right. With a cr2034 you should use a diode to block current from board to try charge the cr. Hope it helps.
The circuit topology of the CR7 is more or less the same as the Dragon layout which uses 2.2uf coupling caps instead of the 1uf values and also using the same OP Amps. Perhaps Nakamichi designed it this way as the CR7 is renowned for being more CD like sounding and clinical losing that analogue sound, which is criminal IMO!
The battery is to store auto calibration parameters, you can read it in the owner's manual under auto -calibration, page 8
Good job.
Great job!!!
Thanks
Which brand and capacitor types are you using. Why are Electrolyt caps better than mkp's?

Thanks for the tip, I will check
You are wrong, schematic and PCB layout shows this as a battery and there is diode installed.
One of the hardest for anyone can work on the CR-7.
