Hi all , having bought one of theses units & getting used to it for the past four months I like to think Ive got a good unit that will last for a good period & has a bit of an upgrade path .
All of this is just my own poinion & point of view but if it helps anyone then good .
The main unit has a good solid feel to it & has good build quality as do the small speakers , all units are weighty for there size .
The auto setup is not to bad only needed a few tweeks to get it sounding nice ,It has needed about 5 weeks use to get it run in but that is not a large consurn . Having sat & done a running comparison with the hi fi playing the same tracks while running in ,it dose a good job of music but not as envolving as I like my music to be .
The great plus side is its great at doing the job it was bought for surround sound , having set it up as a 5.1 sytem & played many dvd's & a few blue ray discs my I say its a good unit to listen to & steers the sound very nicely & from gentle to very dramatic without any trouble .
I am very pleased with this unit . as for upgrades then the speaker cable is first then mains then front & rear speakers if needed then on to 7.1 sound .
hope this helps
