MBL 1511 DAC - Made In Germany

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
This was a very expensive DAC back in the late 1990's.

This 1511 is in fair condition with some scratches and nicks on the highly polished case, typical for this sort.

The only input that works is the Optical, but it works great.

Balanced and single ended outputs work well. Unit produces a very clean and precise output.

Very little info on the internet for this piece, sorry for the lack of our usual content.

Testing Process:
We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect resistors and other passive components for signs of overheating.

After the visual inspection we connect the DAC’s RCA outputs to our Sencore PA81 Power Analyzer which simulates a real world input impedance and allows us to monitor the output on an oscilloscope. We are equipped to test optical, coaxial, and USB inputs at Redbook CD Quality. We start with a test signal to verify signal lock and proper output on both channels. If the DAC has balanced outputs these are also tested at this time. If the DAC has multiple Optical and Coaxial inputs they are all checked for proper lock. USB inputs are tested with a Macbook Pro.

After proper function is verified, we set the DAC up for a listening test to evaluate general audio reproduction quality and monitor for clicks, pops, or any other audible signs of issues related to dropped signal lock or failing audio output stages. We often connect DACs under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions.
