Good to know you got your issue solved

Upgrading from say, onboard sound to a DAC is a HUGE step and it's easy to spot the differences immediately. Trying to tell the differences when moving from a good DAC to a better one is much harder though. Listen to your stuff with the uDAC for about a week, then switch back to the EF2's built-in DAC. Usually, it's hard to see and changes or improvements when going up the chain, but you quickly spot the differences when you downgrade equipment, since you're already used to higher-quality sound.

Leaving them both plugged in via USB will make doing a little A&B work easy. No switching cables except your headphones - just switch outputs in the PC or player, and switch the EF2 back to DAC, and you can test them back and forth.

Not a bad set of options you've got there in two devices, either!

What about using a Vinyl player to connect to an amp. Is that possible? I've noticed there is always a mini out from the vinyl player, but I don't know what to do with it.
