In terms of reliability I regret still change the battery of memory (a few tens of euros) after 2.5 years because I switched off the amp completely between 2 sheets that do not too obviously. I also had a small breakdown of components (one hundred euros) to be deplored. So I would say that reliability is average, although it continues to make me the services I requested.
In summary the April allowed me to enter the world of HC and I could help him "grow" through its inputs and outputs rather complete. His party does not allow amplification Hifi use except perhaps with high performance speakers that I have not tried.
