4.5 A prince amongst amps Bigal1870 | 29/12/2008 | See all Bigal1870's reviews (36) I have always thought that Onkyo AV equipment was of superior build quality and their range of AV amplifiers reinforces my belief that for the money they are hard to beat.I bought the 606 a couple of months ago to support the latest HD audio sources available on Blu Ray discs and it has performed superbly. The 606 is capable of supporting a 7.1 system and whilst it isn't the most powerful home cinema amp out there, for the average AV set up it is more than enough to make the house shake. The 606 supports Dolby True HD and DTS Master Audio as well as the PCM lossless audio also offered on many BD discs. However it is not THX certified, but this isn't really an issue.The set up menus are easy to follow and the unit also comes with a supplied Audessey EQ microphone that measures the distance of your speakers from your listening position and sets up the amp automatically. However I found that the auto set up tended to tone down the speaker output making it a little too quiet for my taste, so the manual set up was the way forward for me.The unit is a big box of tricks and is reassuringly heavy. It's looks imposing sat under your TV and usually draws comments from people who are not AV o'philes.If you are thinking of updating your AV amp any time soon The SR606 is definitely worth a look.
