Ferrofish is owned by the same parent company as RME, so when I was looking to expand my Fireface UFX+ I figured it must be good....and I was wrong...it's AMAZING. Conversion is top notch, feature set is everything you could want and then some...I also own a Pulse 16MX and that is no slouch either...You cannot go wrong with this box if you need to expand your channel count.
