Hi,

Nope, no problems at all. I used driver longer cables into 10K loads in my own setup.

The key is your source, not the load so much.

Something like 200 Ohm output im pedance, 2V full scale output. Typhcially all CD Players will be much like that, but some unusual esotherica will be different and might cause issues.

Which CD Player do you have?

Ciao T
