Thank you for your kind comments.
My dealer is very knowledgeable about Linn matters and has been selling their products for decades. He is on Facebook every day advising people on Linn stuff old and new.
However, I am sure he’d never claim to omnipotent and there’s always room for individual preferences. I don’t know his views on wall shelves. I think he was just saying that a metal shelf might resonate.
On the other hand, my wife is omnipotent. I wouldn’t dare say otherwise :)
