For me personally absolutely, No. I liked U12t for everything but the bass as it doesn't sound like the kind of bass I'm familiar with. It can go low enough and even have enough impact with the help of a good source and cable plus a bit of imagination, but the timbre is still like you hit that funky frequency on a keyboard: A bit lifeless. So although it reproduces the frequencies completely correct and with the correct amount you won't be thinking there must be a juicy bass guitar or acoustic bass playing out there. It does have its advantages though, especially if you're listening to fast music where the speed of the bass can be more important than the timbre as you can follow bass lines better. So as always it depends a bit on your library, your reference, and what you're after.
