With these types of amps, that's really the key - how easy is it for you to operate it. With all of the features, there is some complexity in operating it. If accessing the features isn't intuitive to you, then they are useless because you won't use them.

If going into a store isn't an option, I'm sure you can find tons of demos and reviews on YouTube. You can probably download the owner's manuals from the manufacturers' websites.
