These days you can have everything for nothing.
There trouble is it sounds pretty poor.
How much do you actually have to spend to own an av amplifier that is a joy to use and actually sounds any good.
There are different bands. From £ 400 some products will work well with a satellite speaker package.
To work with better speakers and have some grunt you will need to go to £ 600-900
The next level up is a large step in sound to a specialist brand such as Arcam or Anthem from £ 1199
From there on there are big differences again, as long as the rest of your system is up to it.
