The NL-12.1 is rated 8/10 for age and unknown # of owners—I don’t know the full provenance, however, it is cosmetically and functionally excellent. It comes with original manual and aftermarket (but nothing special) power cord. Those spots on the top cover in pic #2 are flakes of dust, not damage... I had to take @ 50 pics just to get these as the varying aluminum finishes are very difficult to photograph. This amp uses the unusual NPN Bipolar transistors vs. the almost ubiquitous PNP type for a "sweeter" sonic signature. For me, the sonic signature is reminiscent of my Pass Labs 350.5 FWIW...Please see my ad for the matching Signature One preamp, I will make a discount if a buyer purchases both of these items. From Edge Audio's Web site: ""The EDGE NL-12.1 Power Amplifier provides extraordinary wide bandwidth
amplification. Using EDGE proprietary Laser Biased Control circuitry this amplifier
redefines "linear". Massively constructed, yet conservatively sized, the NL-12, with a
full 50% more available current than the NL-10 will elevate your experience from
"Listener" to "Participant" in the medium of your choice.The NL-12 is excellent for systems that either: need or want a fair amount of power,
are too bright, the listener would like to use tubes but cannot or does not want to deal
with tube's negative environmental issues (heat, maintenance, foot-print), or those
systems that do not have enough PRaT (pacing, rhythm and timing)." Technical highlights: "Dual Mono, single chassis.
Two 1500 VA Toroidal transformers.
Each transformer operates at 96% efficiency. Regulation equals 4%"
