When mastering solely within a DAW, the sound can lack depth and become unnatural if you try to push the loudness too much. Therefore, I used to connect it to a clock and utilize the internal digital compressor, etc. This year, likely due to aging and capacitor failure, it stopped powering on. I'm selling it cheap to someone who can repair it. There's a strong scratchiness in the earphone volume, but it goes away after turning it a few times. *This is a junk item, so please understand that it's non-refundable and non-returnable.* I'm starting to declutter, so I'm open to some price negotiation. Only those who can pay promptly, please.
