Well that’s a tough one for ME to answer. Unobtrusive is definitely in the eye of the beholder. I’m a nuts and volts kinda guy and I will regularly take my speaker grilles off just to appreciate them. Hell, I even think a Top fuel dragster is a work of art!

@Pogre said, performance and elegance are sometimes mutually exclusive and a big factor will be budget. Also, depending on what YOU want to see vs what the boss wants will be between you two. I’m also not super family with your mains, so while I would recommend something similar in timbre, others may feel it’s not necessary. I guess that would depend a lot on your personal experience/expectations.
