Fredenstein Bento 6S

I bought this Bento 6S with my first two modules.

Great sound, no noticeable noise from the power supply, plenty of connections capabilities, best budget option on the market.
Construction-wise, one could wish it had lockable XLR connectors, but the overall build quality inspires confidence. The integrated power supply comes handy, when moving it around (most 500 racks have a separate power supply which should help minimize electrical noise)

ONE BIG ISSUE though: after filling it up with 6 modules (only preamps from reputable companies, no DIY), I had to face the dreaded and already well documented issue: the 500Hz noise. in my case it appeared as soon as one of the modules would have 48V phantom power activated...

I can not tell whether my case is isolated, as the "6S" revision was introduced to cope with this issue initially present on "6" units.

Thanks to Thomann customer service I was able to exchange it in favour of one of the competition which works fine.
