We have a matching preamp to go with the A40 under development.

The new chassis arrived. 350mm deep heatsink. It is massive and heavy (29lbs of anodized aluminum). All walls are at least 5mm aluminum. I like the custom trafo L brackets. All hard mounting points for standoffs and MOSFETs etc are in place. All the crew holes align and fit perfectly. The lid fits perfectly with no gap and is square. Wonderful CNC machine work quality.

We have a Schaffner EMI filter between the IEC mains and PSU board. Internally, the amp is all linear so the main noise we deal with is 60Hz mains hum radiated from toroidal trafos. Setting them vertically and keeping distances and playing with alignment and orientation while observing B field with a magnetometer helps. Final proof is uV rms measurement of amp output noise.
