Yes. It is hard to hear the difference with Ipad's tiny speakers. May be ear/headphone with Ipad will help you to hear better.

Your hearing is right on. More mid-range on #2 speakers. I think 70-80% of music is better off with #2 speakers. #2 speakers will be played for the most of time at the show. However, depends on music, some recording with clear mid-high frequency imaging are to die for with #1 speakers.

Thank you for comment and kind words!

Yes. I am taking them both speakers. I need a back up speakers anyway. Also, every rooms are different and anything can happen with the sound. Though, the show location is only 20 minutes driving from my shop. My audio set up is very simple and light. My whole audio system consists an Oppo dvd player, a shoe box size integrated amp, and smallish bookshelf speakers.
I will play few familiar/well-known songs at the show. That way, guests will hear how my sound is different from what they've heard.
I might record songs you list and upload in Youtube if I can download them. Downloading Ytube video is harder than before.
Many thanks for all members comments!
