Would getting a pair of Maggie 1.4s be an upgrade?

Not surprising the Maggies sold. I likely would have bought them for $200 if the seller responded. Good deals like this go fast.

I would continue with Craiglist searches. With your budget and music preference, maybe look for a pair of Paradigm Studio 60s to pop-up. I bought a pair on Craigslist a few months ago for $175 from a seller in Mesa. They were v2 and in great shape. The Studio 60s are good for your listening tastes and budget. Since you have a SW, maybe consider the Studio 20 or Studio 40 bookshelfs.

I've seen B&W DM640s on Craiglist for less than $500/pair another good choice. Also, look for B&W DM602s -- a large bookshelf monitor that is VG for rock. Depending on the version, you should find a pair for less than $300.

"With a tight budget (<$500) can you folks recommend something that will fit my bill? "

Since you have a sub already, you do not need anything too big or extended, but speakers that can do the rest that the sub does not very well. A pair of Triangle Titus monitors can be had for <$400 used. These often get recognition as one of the best speakers around in their price range and I would have to agree. Integrate a good sub well and you have a sound that can contend with the big boys.

Same true with Maggie mmgs which you might be able to find used in your price range.

Another option would be to look for refurbished OHM Ls at www.ohmspeakers.com. You might be able to work a deal to get these newly refurbed from teh factory for $500 or less maybe. I've had mine (with some mods) for over 30 years now and they hold up quite well. I can say from experience that they particularly shine with the kinds of music you identify, specifically Porcupine Tree. Fear Of A Blank Planet in particular sounded so good on mine, that I was tempted to just go with them and ditch my upgraditis at the time.

Thanks. Just out of curiosity, are the Boston Acoustics really that bad? To my inexperienced ears, they sound pretty good, but maybe that's because I don't know any better?

Still, thank you all for your responses.

Stevesctt - you are the only person I know locally that knows (a lot) more than I do. I'm going to be picking your brain a lot more if you don't mind. :)

fwiw, any Boston Acoustics speaker I have heard has been a bit bright. I do not know your particular models however...

I recently have been listening to an old pair (15 years) of Sound Dynamics 300ti speakers that are very good and can be bought for $300 or so. Nearly full range and easy to drive too.

I think it may be a good thing the Maggies are unavailable as they are difficult to drive and need lots of room as well.

Maybe try this angle regarding your stereo: what are you looking for? or: what are you unhappy with?

I used to have a pair of small Boston Acoustics. They were very popular back in the 80's. I had no qualms with them. Its a matter of personal taste.
