So let's bring this down to a commercial level,
Specs have no 'real' affect on how it sounds in terms of tone? They can tell you how loud it goes? Is that why alex, you give the one month return period?
Possible rant
Also why do many manufactures have so many different spec listings? Shouldn't there be a unified code of specs that the manufacturer has to produce? I realise that tone is personal. But as a consumer, I feel with local music store shutting up shop and internet shopping taking over, I personally think that without unifying a spec sheet as to how things are done that it is very hard to make a calculated choice. As trial and error can be expensive.
