I'm looking at a used BCL to pair with my HD800s. I am trying to verify the approximate build date. The serial number is in the high 2000-2100 range. Can anyone give me an idea based on their serial number and purchase date about this amp?
I emailed Lehmann asking for info but my first email has not been answered after over a week and I just sent a follow-up today.
Thanks to all,
dave
