Benlink,
Great analysis of the information!
But...
The Stiletto is just an EL-34 amp -- not 6L6. As Matt states in the review, "Although equal in aggression, the Ace’s high gain assault is sonically an ocean apart from its Recto cousins."
So while the Stiletto will make great sounds to sooth your metal beast, they will be significantly different tone-wise from the sound of a Rectifier.
In some ways, this amp finally enables two guitar players in a band to hapilly co-exist with both of them playing Mesa/Boogie. I know a lot of bands, my own included, where one of us plays Boogie and the other one plays Marshall or another brand in part so that we have very different tones that aren't going to blend into each other so easily.
Now, one of you can be a Boogie 6L6 player and the other can be an EL-34 guy. Of course you can swap tube types on some amps -- the Road King certainly throws a wrench in this scheme -- but in general, this amp will rock hard and not sound like a Rectifier.
Also, the Stiletto is only two channels, which may not be enough for some people, and it lacks built-in Reverb. If you're happy with two channels and use outboard reverb pedals or rack gear, the Stiletto may be a killer amp for your needs if its tone is what you're after. But if you're in love with the Recto sound, this won't be the right Boogie for you.
As for the ratings, I can't speculate on what a single rectifier would get. We have a very specific review process with rating values that is used to calculate the scores for each product. Later this week I'll try to publish a detailed article that explains the review process/criteria. In the meantime, if you go back to the scorecard at the end of the review and click on the headings for Value and Rating, you'll get the short answer:
Each category in our review gets rated from 1-4 stars, with half-stars allowed. Then, each of those categories has been assigned a weighted value. For example, Sound is worth 25% of the overall score. We list the percentages in the table so that you can decide for yourself how the ratings should be to suit your own needs. If you didn't agree with our weighted values, you could create your own calulations in a spreadsheet.
Next month we'll be publishing our review of the Road King Version 2. We're working on getting other amps in for review from some great boutique companies as well as from some other big names -- it just happened that we were able to get a variety of Boogie amps for review all at once.
If you want more details comparing the Stiletto with a Rectifier, post stuff in the MusicPlayers.com forums and Matt will be happy to talk about this with you (he doesn't hang here -- we try to participate in different forums so we see what lots of different players have to say about gear).
