hc78A leak
Published on 04/20/14 at 23:45 (This content has been automatically translated from French)Servo 120a presented very well, nice finish, thickness 1U, silent, full connectivity) and no hum. It presents more outstanding sound quality (8-ohm speakers) and competes with amps very high quality (in stereo). It is regrettable that the design is bad. These amps break like glass. Two amplifiers purchased in 2010: 1 meter with hs seen in 4 months, 1 with lighting HS in 5 months. Bought a 3rd amp end de2013: not illuminate, it is 6 months ...
A buy to have the pleasure to send one month in service every 5 months ...
Very sad
Use: small power (below watt) in home cinema

My opinion
Goodies: I just try it and I was immediately surprised by its power, its sound transparency and weight (7kg). Very neutral and dynamic sound obtained on my speakers Bang & Olufsen hi-fi can be enjoyed all the details of the music. The cooling of the amplifier is natural convection, so no fan, which gives us a very quiet amp as more and no breath is audible. I did work many hours without finding a normal diet over temperature (just warm). The connection is well made: RCA Jack Gold, fast way hi-fi amplifier for the speakers. 2 Meters 10-segment Led to view the output.
Cons: provide a solid attachment for the rack as the animal weighs weight (7kg), on my model I have noted a small shift of the noise at low power due to the serrated knob.
Conclusion: a very good amplifier for monitoring the quality / price excellent. Manufacturing is neat and the design is much more friendly than its competitors. I would do the same choice without hesitation.

In dpart, j'tait facing the Crown D75 but not the same prs perfs, it i is very well.

I just got this little amp & APRS mix over one week I am super happy! My Tannoy relive littralement (before I had a simple stereo amp). The gain in opening and enlargement Stereo is standard.
Its main default, I do not really see except maybe a color trslgre ds treble but it is soft & then the weight (7kg).
150 qualitprix bought the report is fabulous. go for it!
