The v1.9 software update has been released for Arcam's AVR600 and AV888 amps, which aims to fix 'lockups' when changing source as well as other minor bugs

As you may have noticed if you read our Forums, the otherwise excellent Arcam AVR600 has been suffering from a few bugs and glitches that do their best to detract from the amp's performance.

A v1.9 software package is available for the AVR600 and the AV88, and can be obtained by emailing Arcam on

The two main fixes aim to 'suppress switching noises on input changes' and more importantly in our eyes, 'prevent random lockups on source changes'.

A whole host of other 'minor bugs' should be fixed, too, as you'll see from the list below, some of them sounding more crucial than others:
