I'm actually loving this. I like to see what it is about Tone (capital-T) that makes people all excited and want to fire off screeds about why BoogieVoxMarshallFender is the best at whatever the hell it does.
So much of this depends on how you intend to use the thing. Are you looking for the perfect clean tone at recording level? Stage volume? Do you need to be loud enough to punch though a PA mix and stay perfectly clean? Or do you just want to be able to play privately at bedroom levels and enjoy that sweet sound all by itself (not that there's anything wrong with that)?
I'm lucky enough to have a handful of basically wet dream amps (see sig), and I appreciate them each for different reasons. But I have to say, that damned LSC is really floating my boat right now. I love my Deluxe, but the LSC gives me some things that the Deluxe doesn't, and I'm speaking specifically about the clean channel.
As spankin' as the Deluxe is, I can shape the cleans in the LSC with more precision and flexibility, at basically any volume. I have tons of headroom and the ability to push it just a little (or a lot). I can make it clear and crisp, or sneak a little crunk in there for some subtle bluesy vibe. I can stiffen or soften it without losing any clarity or any of that bell-like chimey goodness... again, at any volume. (The Drive channel needs more volume to show its stuff, but the Clean is there right away.)
I had my eye on an LSS originally, but a good deal came up on my LSC and I'm glad I took it. As sweet as the Special was, in the end the Classic won out because it gave me more headroom and oomph, more snap. The LSC actually reminds me more of a Fender in the way it pushes back a bit. I play pretty hard, so that's appropriate for my style. The larger cabinet also contributes to the feeling of more air pushing through with each chunk-chunk.
Because of all of this, I could totally see the LSS giving up a little bit of pop and clarity in big room. It's so responsive and cool because it gets to nirvana at a lower level, right? If that's the experience, I'd invest in a good monitor setup and dial in your perfect sound (as suggested earlier).
