Many of you pondering getting the Onkyo TX-SR 605, may also be considering its slightly older brother, the Onkyo TX-SR705. Although it is a £200 additional cost ($200 for US home cinema fans), you do get some additional stuff, that is quite worthwhile…
- A slight power upgrade from 90 to 100 watts per channel – useful in bigger rooms, but 90 is quite enough
- THX Select2 Certification – a nice badge of honour on the front!
- 3 DSPs – Not sure how many the 605 has
- An extra HDMI and Optical input – 3 of each – which is a very worthy addition
- 7.1 pre-out – the 605 only has a subwoofer out
- Better auto set up – Audyssey MultEQ XT rather than Audyssey 2EQ – although the latter is quite good enough
- Input source renaming – very useful for knowing what goes where
- Fan cooling – useful in environments or positions where the vents can’t do their job sufficiently
- Really cool blue LED lighting around the volume knob! Call me a geek but I loved this!
- You also get binding posts on Zone 2 speaker outs rather than clips
And some stuff that is still worth having, but not a major benefits:
- A power input socket so you can upgrade your power cable if you wish
- A 12v Trigger
- Learning Remote – I use a Logitech Harmony so this would be of little use
- A Phono input – could be useful for the 2 times a year I dust down my vinyl
- THX listening modes – probably worth a play now and again, but not essential
- Absolute or Relative Master volume scale
The differences seem to be mostly feature based, and from what I understand, the difference in sound is negligible, but if you need the extra features and can justify the extra spend, the Onkyo 705 is probably the better bet.
