I don't think they're saying anything bad about the amp Billy, in fact it looks like a really well built little guy, more that Jude's review doesn't really make sense:
"If you thought your UE-10 Pro was already excellent (and I'm sure it is), you may be able to effectively increase what I'll call its "sonic contrast ratio" with the Tomahawk" It's sonic contrast ratio? what the hell is that supposed to mean
"The sound of the rig in the above photo is very balanced, very resolving, and entirely high-end as far as portable rigs go" entirely high end as far as portable rigs go? Again, what the hell does that mean..... a nano is high end now then is it? Absolute bollocks.
