V2153

I did order this IC for building the soundnicer eurorack module ,
the IC nicely fits the smd footprint on the pcb i aquired.

the whole design of the pcb i aquired seems to be just copied from the datasheet using the resistor and capacitor values shown in the schematics at the datasheet ; which will probably make it work.

The information in the datasheet did not provide any information on how the resistors in the shown schematics operate ,
so i went for ordering the most used values i was able to aquire and am still waiting for them to show up.

IC looks like a genuine ( not sure whether that is possible or even exist as many ICs are clones from the originals or are being produced with the original machinery that after it had been gathering dust for decades have been bought and restored by Ullis team to benefit not only his brand but also all that repair , refurbish , design and maintain music gear , at least thats what i understood so far ) coolaudio product.

waiting for the 21.5 k resistors and will do most likely some tests with the other resistors to actually hear the result , the original BBE Maximiser in most of its incarnations did not sound properly in the hands of most of its users anyway so some adjustments on the circuit could improve its range ( the odd valued resistors seem to act as filters for frequency bands and shifting these can work beneficial to the sound )

When possible i will share my findings here.
