Etymotic will replace the broken driver for $80. Even with the high shipping, it's still a good deal. Also, changing tips can improve the bass. I use Klipsch tips with mine. Shure olives are also very popular.
Etymotic won't fix your headphones but will send a new pair if they're under warranty. For out-of-warranty phones, there's a program where you can buy a new pair at a discount. http://www.etymotic.com/cs/
There are 2 companies that make double-flange tips that will fit Etys.
Futuresonic: 3 pairs for $12 small, medium and large
Klipsch: 4 pairs for $13.99 small and large
Klipsch tips run small so Futuresonics might be a better fit for you.

You don't need a USB turntable. A better option is the ART USB Phono Plus preamp. It turns almost any turntable into a USB turntable.
