Bricasti M1 owners- a question-

See Additional info on these jumper adjustments from the Bricasti M1 DAC Manual:

“For custom level matching, an internal the jumper on the board can be moved to engage a precision adjustable potentiometer. This adjustment is set from the rear panel screw near the XLR connector. When the potentiometer feature is engaged the level is adjustable from +8 to +23 dbm and can be referenced to a fraction of a db to match any setup.

This level is set as a default +16 dbm at the factory so when the jumper is engaged this will be the new level. Please contact us for detailed instructions on how to change and set these levels. The unbalanced is set to normal hi fi levels of 2V RMS (+8dbm) by precision resistor values on the board”. 

As noted, a jumper on the board can be moved to engage a precision adjustable potentiometer.  If you plan on doing this, please call Bricasti Customer Support for assistance.   

@hgeifman can you say what the sonic difference is from your M1SE to the M21?

I’m aware of what the owner’s manual provides. What’s interesting is that the unbalanced output is set at +8dbm and the fixed balanced output is set at +13.5dbm which is a bit odd as it should be double the unbalanced output. And yet by moving the jumpers you do get +16dbm, without needing any other adjustment at all. 

@rsf507, The Bricasti M1SE DAC is very good and the Bricasti M21 DAC sounds much better (In my opinion). The M21 DAC includes both a sigma delta DAC and a ladder DAC.  The M21 has great detail, is clearer and is very musical.   I suggest you give it a listen.   It is truly amazing.  

Set the output fixed level so the digital volume control is up near full for loud listening, this way you won’t run the risk of "bit stripping" if the volume is too low.
