I hate to have to post this again regarding Sherwood but your going to get a much better response from US sites. Sherwood are rated much higher in the US and they have bigger distribution channels, the only retailer in the UK which sells Sherwood equipment is RicherSounds (thus little of it is reviewed). Sherwood does make quality products and for their price they are often very good, however like all manufacturers I'm sure they make some bums too.
You should get a much better response from

(EDIT: Forgot to mention Sherwoods Sr. VP for Marketing and Product Planning frequents those boards - and no his name isn't Stuart

- he may be able to help give you some reviews.)
One more thing tho, if your happy with your sound then enjoy it. When you start getting people telling you you could get much better you may get into a game of endless wondering and end up thinking your sound isn't that good after all.
