I too am a big fan of A&H kit, I use a 64 channel iLive rig, a GLD24 and various Zeds with the company I do a fair bit of work for. No issues and good sounding kit. Fearsome expensive though compared with my X32s, the AR2412 is about right compared to the S16/32 but the AR84 is expensive at between £500 and £650. The GLD-112 desk is over £5k with a 24/12 I/O stagebox, an X32 plus S32 is around £3.5k and has 8 more channels.....
