Re the Ion "Profile LP" USB turntable:

• when you hook it up to your computer, I don't think you can listen to the music in real time. You need to record the music to a file first, then play back the file
• it does have a line-level analog stereo output, which you can connect to any home audio system for listening to music in real time

Yes you can pay for an on-line purchase with a gift card - just enter the card number in the space provided during step 3 of the checkout.
