QSA Gold AC Adapter

I have 1 Gold level ($5000 MSRP) QSA AC adapter. It is in excellent, 9/10 condition, non-smoking environment. Approximate age is 1.5 years. There are no moving parts and the treatment to the metal is permanent. So now is a great opportunity to own the Gold level QSA adapter at more than 50% off of retail. 

The QSA AC adapter plugs in between a power outlet and your power. With the Gold level treatment, you will hear significant gains in resolution, soundstage, and naturalness of the sonic presentation. It's difficult to imagine something so small could make such a sonic difference in one's audio system. But just like the fuses, the AC adapters deliver improvements unlike any other tweak on the planet.
