Will Luxman not look up the serial number for you and tell you mfg date? I’m strongly considering Luxman but have been wondering if they will do this.
I am a Simaudio owner and also considering a used preamp from them. I took the serial number from picture and emailed to CS. They ALWAYS get back to me in 24 hours via email. The unit I was looking at 5 years old. Seller said unknown (third party seller)
But I would feel more comfortable if Luxman did same. Not sure if all mfgs will do this for you based on serial number.
But with a 24 hour turnaround from Simaudio does not impact a sale which is pretty awesome. Also not sure I’d buy on EBAY and especially from Japan. But if your going to try this maybe try the serial number thru Luxman for mfg info.
