it's just one thing i don't like. the Hypex softstart. damn that relè. it burns all the time. everything else, i just love

the sound is lovelig. the amp is stable from start. DC offset cold=22mV warm=25mV.

by the way. i had to modify the softstart a bit. the 33ohm 7W resistors in series was riped out, and 2 10ohm CL-60 in series got its place.
i hope that stops the relè from burning. if not, i'm gonna replace the 16A relè with 30A relè

and who said that aleph amps produce to little bass? my amp are crushing hypex on all points.
its natural deep bass, crystal clear mid and tweeter. it is so detaild that most recordings suffers.
you can hear everything they mist in the studio. and that is alot

hehe

I don't know who said that about the bass, but they were lieing, I finaly got a stereo pair of the mini aleph going today, and being my first DC coupled amp they are meaking me sweat bass wise, they just go so low and without mercy, hard to believe its only 10W.

I've been torturing my Mini-A for some time now with two 12" parallelled into 4 ohm drivers in an open baffle. Hasn't burned up yet. It gets good bass down to 50Hz and further down with less impact.
