Any balanced output possible? Casio GP

[Fluffynator]

TLDR:

Is the Casio GP capable of balanced output to connect to a DAC (eg. via USB-B)?

 

Hi,

 

I am using Sennheiser HD600's connected through an external Amp through the RCA cables.

I was wondering if there is a way to connect my GP310 to a DAC/AMP. I want to achieve a balanced output in the process (and of course I would also buy a balanced cable for my headphones).

I figured the RCA output of the piano is inherently unbalanced, so these are are out. There is still the USB-B connection which I can connect to a DAC. But according to the manual it is only to record files. Does it still output raw data to feed to the DAC? I dont want to spend alot of money to find out. From what I figured I also cant circumvent the internal DAC of the piano. But I'm hopefully wrong.

 

Thanks guys

USB on the piano does not transmit digital audio.  It is only for MIDI.  You would still need to use the unbalanced analog audio outputs.

Have to see the schematics-see what the audio output consists of. could be dedicated op-amps already, or nowadays could be integrated into anther style of output IC. Years ago, there were companies who promised higher quality audio outputs by installing better quality op-amps and related lower noise components in the output chain. Results were not spectacular.

Maybe you coan try to use a passive DI box and get a transfomer-insulated output.

@Jokeyman123 I remember that in hi-fi circle swapping op-amp was a thing. Now it's true that there were Philips-branded and Marantz-branded CD players that were very similar, had the same circuit board but some of the circuitry was different, and the Martants ones were sold at a premium. You  could desolder components from the Philips, put the components used in the Marantz and get the better performance, but I duppose was more cost-effective buy directly a Marantz.
