Well... it's bootleg quality. A bit better than some other bootlegs but don't expect it to sound as good as "No Sleep 'Till Bedtime", for example.
I was a little disappointed by it but maybe I'm a bit too much of a perfectionist.
I don't agree that it is bootleg quality - most bootlegs sound like shit. This may not sound like a professionally mastered show but it is by no means bad quality.
That said, the thing about Devin live is that his disks sound so damned amazing, so fucking immense and so incredibly detailed that any attempt at a live simulation is inevitably a little dissapointing... When you are there, it's a little different, simply because he's right there in front of you, which makes even material from SYL's last one seem a little better, but when listening back later.... It's not as much fun.
But if you are a Dev freak then you'll appreciate having a recording from the Infinity tour, and it's nice to buy these disks straight from the man himself so he can make some more money and get more musos onstage! He needs a thirty piece band!!!
