Bought this at the beginning of December 2015 because it felt good value. And when it works so it is ok for the purpose.
I bought it because it was the Pre-Out for fronts and 2 Sub. Driver front speakers with a Lyngdorf TDA2170. So in the current situation it is only used to power a center speaker.
Unfortunately, I have already been obliged to submit the twice warranty service because its protection circuits tripped too many times (it is in service now ... :()
It is possible that it works with Lyngdorfen what do I know. All other equipment such as DVD players, network players, CD players, etc. working properly.
So if you are looking to use it in the same way as I do, I recommend not.
Several great features, YPAO works better than expected. Thought replace my Onkyo 605 against this but experienced sound flat without heat. The amplifier is possibly too weak for my speakers or have other problems when my 7 year old ONKYO paints a more significant, realistic and warm sound. V779 how that went on the trip in search of reaching more powerful and warmer.
