47 Labs 4706 Gaincard with 4700 50W PSU version / DEMO / Mint Condition

Item Description

On Offer is a Demo 47 Labs 4706 Reference Series Gaincard amplifier along with its Reference 4700 50 W Humpty Power supply. The 50W PSU is the higher power version which allows the Gaincard to deliver 50W per channel into 8 ohms. List price for this combination is $4,650. These demo units have been on display for just over 1 year, are in absolutely pristine condition and have less than 10 hours on the clock. Will be delivered in equally pristine original packaging and documentation.

The seemingly lowish 50 W p/c rating is very deceptive in this case...the Power Supply is massive and has tremendous energy reserves. This amp will drive difficult 83-87 dB / 4 ohm loads with uncanny ease. If sheer musicality is what you seek, this is an absolutely "true to the creed" design, executed in the zen-purist tradition by one of the Masters of the Art himself. A "classic" if there ever was one. Sleek, Simple and Stunning. Have a look at the tradition of quality behind this mystical Brand :
