Well the SM3 has good bass imo with plenty of punch and good depth but I have to tell ya now that I got a pair of Ortofon e-Q5's again I think they sound as good and even better in some cases as the SM3 and UM3X. They're warm yet brighter than the SM3 and UM3X with mids that sound ever bit as good as the other 2 and they also have a spacious soundstage and good 3D imaging. For either around $165 or $198 depending on where you get them are a great value and have truly top-tier sound and build quality.
I know I'm pushing the e-Q5 hard but I really think they're that good but the SM3 and e-Q5 are pretty much equal as far as sound quality goes though the e-Q5 has much better build quality. So I think for what you want either the e-Q5 or SM3 would be a great choice.
