Audio Note M6 line perfectly working.
I don’t know manufacturing date because I’m the second owner.
The unit works perfectly. I can sell a full set of new spare tubes if you like.
No original packaging, but I have a perfect fitting packaging for it. Can do safe shipment.
I have a 4 way high efficiency system with active crossover and Audio Note power amps. I switched to a solid state pre amplifier, this is why I’m selling the M6.
I always used audioquest cables.
