Line Magnetic…….the difference between LM-210ia and LM-219ia besides output power?

[Dr Morbius]

Hi, I was wondering how the sound is between the Line Magnetic LM-210ia , which puts out 8 watts and the LM-219ia which puts out 22 watts of sound. My speakers are 105db sensitivity and 8 watts is powerful enough. It’s the sound that is possibly different. I have a feeling pretty much very few have heard them both but if you have I would love to hear from you.
Thanks!
Steve
