Default Modding the Benz Micro PP1 T9

Anyone have an opinion on fitting hexfred diodes to a Benz Micro PP1 T9?
(Benz won't talk about it)

I've read mixed reviews of hexfreds; the results (better or worse) seem to depend on the application.

What's your experience with hexfreds?

Also, has anyone performed other tweaks to this product?

Take some pics of the internals...

I would have thought Schottky's would be preferably to Hexfreds

Internal layout and parts.
Maybe I need to re-engineer for a new platform with Audio Grade parts and accessories.

I have a Benz Lukaschek T8 Phono stage, which I modified. I replaced the standard power brick with a heavy duty toroidal transformer, which brought significant improvements across the sound spectrum. I also removed the stock diodes and replaced them with high quality HEXFREDS. The switch to HEXFREDs made a huge difference to the sound. My amp now sounds vastly better than stock; in fact, it sounds like a different amp. Dynamics are improved, bass is more extended and rounder, the mid range is smoother and so are the highs. There is better definition all across the sound spectrum. The amp now sounds effortless. I highly recommend these changes to the Lukaschek; however, switching out the stock diodes for HEXFREDS is tricky.
