"After purchasing two HX350 from Michael at Ampslab,
I was impressed with the service I received and the speed
of delivery. Michael
was happy to answer all my questions, providing excellent
after sales service also.
terms of building the HX350 amplifiers, I was happy to find
the instructions and circuit diagrams supplied with the HX350
very clear and straightforward.
to the HX350 amplifier reveals an amplifier with low noise
and a high level of control. There is a lot of headroom for
large transients in music. I find the sound to be very clean
me the best part of the HX350 module is the ability to double
the standard output stage. This allows literally double the
output power with the benefit of increased stability into
low impedance loads.
you are contemplating a high powered mosfet amplifier and
you need flexibility in terms of output power or what style
of heat sink and case you wish to use, try the HX350. In my
opinion, the HX350 kit really brings high power, high quality
amplification within reach of the home constructor."
