It's certainly a looker, stacked like that.

Btw, what DAC chip is inside the BDA3?

Not sure sorry.
Sold the 4bsst2 though. I've gotten rid of all my speakers. Going full headphone as I like it much much better. Mo more room interactions.

Nice. Thanks.

great deal , where did you order it from

Did you contact Adrian? He is asking me.

no i have not, car problems now so might be awhile

Has anyone had any luck performing the gain reduction mod on their own? If so, how complicated is it? My primary set of cans are Grado RS1's and I can barely get to 9 o'clock without endangering my hearing.

I haven't tried it myself, but what is reuired is simple. It requires couple sets of resistors to be swapped positiions. Resistors 3RF and R10L will swap positions, and 4CF and R10R will swap positions.

The challenge is taking off resistors that are surface-mount that are closely packed together. Surfacemount components are soldered to the pcb bonding pads at the two ends. Trying to desolder this component require two soldered ends to heat up with the soldering iron close to the same time to desolder it. That is the challenge. It's probably not easy with a single soldeting iron, and it may require a special tool to do it properly. Ideally a tweezer like tool that heats up both soldered ends to take them off effectively.

Google desoldering surfacemount resistors. Tweezer like soldering iron exists! I'd highly recommend such soldering irons to take them off, and be careful not to solder nearby surfacemount that can short them out!

Maybe trying with new interconnects might help

This is super helpful... thanks!

Finally after 6 weeks build time.
