I listen primarily to a Sony Walkman CD Player. Please, no snarky emails. I have quite a few to choose from. Headphones are stripped down Grado SR-60s. Those Grado ear pads are just plain terrible. What were they thinking? The Walkman sounds surprisingly good and is up on a 2 Hz iso stand, basically an advanced very high Mass/Springs Woody the Woodpecker stand. Batteries and Headphone plugs are treated with the latest contact enhancer.
