Wow, you're busy Do you load the headphone out with anything besides the soundcard for the measurements?

Into what load?

Usually that should be no problem. Why do you want to do this?

You can watch them on their own, but if you want to get what 24 is about I highly recommend Day 1. That first season had me really glued to my couch, watched it literally in almost realtime. Started on Saturday afternoon, finished Sunday evening...

Yes, and with quite nice results using Grados. With HD600s you'd have to equalize the impedance curve, though.

Please tell me you're kidding, otherwise this is the saddest thing I've ever heard. Enjoying music isn't something you have to learn, either you do or you don't. But if all you've listened to are CDs, it's time to go, no RUN, to some live concerts. Symphony, Opera, Rock, Pop, Trance, Jazz, a...

Yes, likely you haven't set the receiver's bass-management to direct lf content from the other channels to the sub (plug the amp into one of the front channels to test).

Quote: Originally Posted by Andrea Perhaps the amp itself is thought in that light, i.e., intended to give people a taste of the good stuff but not be enough to leave you replete & defeat upgraditis... Just speculation. No, "upgraditis" is simply inherent to our hobby. I think...
