~2 years old and little used. Built using the SiliconRay chassis.
I purchased the parts and then had these professionally built to drive the tweeters in an active tri-amp setup. As you would expect, they sound terrific, but I eventually tired of the clutter associated with multiple amps and moved to a single-box solution. Idle power draw is nil and these were built without an on/off switch, but it’s a simple mod to add one, if needed.
Asking $1,150

Located in Los Angeles, CA. I’ll split well-packed shipment costs and transaction fees, if any. Paypal, cashier’s or personal checks are fine but, unless I know you, I’ll likely withhold shipment until any check has cleared.
