Line Magnetic LM-502CA Tube / Solid State Output DAC with NOS tubes

Selling my gold Line Magnetic LM-502CA DAC. You can easily switch between SS or Tube output. I preferred the tubed output personally. Inputs are USB, AES/EBU, BNC, Optical, & Coax so it's take *almost* anything you can throw at it.

I have all the original packaging material, but not the box. I have another sturdy cardboard box as well as the manual and will ship for FREE at my asking price within the continental USA. I'm pretty sure I have the driver CD somewhere, but if I cannot locate it, I saved the files on my computer and will include them on a thumb drive.

The 502CA comes fitted with an NOS Sylvania 6X4 rectifier tube & a pair of MOS Mazde/CIFTE 12AU7 tubes. I will also include a 6Z4 tube & a pair of new production Tung-Sol 12AU7W tubes.
