Necessary Attire

I just use my golf shoes with metal spikes. A bed of nails works well for evaluating subwoofers.

Keep it simple: Just nail your feet to the floor. Superglue also works well -- you'll never be out of the sweet spot ;-) Hmmm, bed of nails for sub-woofers -- could work.

Decidedly retro and low tech, suitable only for listening to vintage gear. You really need to step up to a pair of these:

You'll notice they provide both stereo and mono versions. The detachable spur on the back is presumably for surround sound.

Yes, those are much nicer!

Yee-hah!!!!
