Great, cheap tube tweak.

I could tell immediately that the music playing on my Njoe Tjoeb 4000 cd player was clearer, better defined, had more presence and in some cases, projected a height and depth of soundstage that were previously missing. Also, transients were clearer and more present. That was immediately. I wonder if they'll sound any better after they've settled in? This is great for a $20 tweak.
