Triode vs. Pentode


I've been switching between Triode and Pentode modes on my VAC amp during the past week. This has been my first experimentation between the two. I'm having difficulty discerning a clear difference, and I'm enlisting the advice of you tube heads to explain what I should be listening for...

Thanks in advance!

Recently I had ny ASL 1001dt 50w amp modded to use either KT88 or EL34 and have been playing diffent kinds of music through Vandersteen 2Sigs.I listen to a lot of solo piano works and as the above posters have said,the triode setting on the amp seems to let more of the sound of each piano note through.That is,the notes seem to hang in the air a little longer.
