Sony STRDE597

Good – I have listened to both this and the 595, which I have personally owned for many years. The sound quality is not up to the likes of Yamaha or Harmon Kardon, but it does the same thing for a lot less money. Plenty of power. Heaps of inputs. Reasonably solid build quality - although some sockets come loose with repeated use. Extremely reliable. Gets hot, leading to the dreaded "protect, protect" error.

Only one small heat sink (see above).

Some parts of the front panel are a bit 'plasticy'.

Screen gets scratched easily - ditto for front panel and less so the top cover.
