Can a Sony MHC-GZR5D support 600 ohm headphones in its stereo mini jack?

I want to purchase an Audiophile Headphone, but I am confused about the right impedance value that would be compatible with my Sony HCD-GZR5D Mini HiFi Component System. The Sony service manual says that Headphones of impedance 8 ohms or higher ( no upper limit mentioned) can be plugged. Can a 600ohm Headphone be used with this Hi-Fi Sony system? Does a higher impedance translate to more clarity at different frequency levels? Do I need to buy an Amp/DAC ?

Should I get such a headphone as I will be using it for listening to music (no recording or mixing) ?

Specifications of the Sony system are given here : https://servicemanuals.us/sony/audio/hcd-gzr5d-mhc-gzr5d.html

Kindly advise for best audio experience.

Those specs don't indicate how much power is available to the hesdphone socket at certain impedances, so it's hard to tell.

However, if had to guess, I would say 'No'. You didn't say what particular headphones you're considering, but 600ohms is a rather high impedance value, and such headphones are usually driven by specialised headphone amplifiers.

A headphone amplifier/DAC could work but only if the Sony mini system can output a suitable signal to such devices.
