Georgestrings, Have you ever worked with an Onyx board? they sound alot better than the sr or vlzs. I own a soundcraft lx7ii and an Onyx 1640 and both sound great. The Onyx actually has some better features than the Soundcraft. All auxes are individually switchable for pre/post. A 4 ladder led for monitoring your levels on every channel. A bnc lamp connector. Every channel has switchable phantom power. A built in talkback mike plus the firewire option all for less money. Mackie as a company is having problems so I would be leary about buying from them now. AS far as tour riders I Imagine you will not find any lx7s being acceptable either. Soundcraft GBs and MHs but those cost $$.
The Onyx series do have better sounding pre's than Mackie's earlier mixers, but it's still a matter of reliability - and I would never trust a Mackie for that when a product by Soundcraft or A&H was available... Mackie is known for adding all kinds of features, at the expense of overall quality - to keep their prices down... The reason why Mackie is "having problems as a company" is because they're been bought out by LOUD - and as we've seen with Ampeg, that isn't a good thing for their customers...
