Actually, my system is far from harsh..
I built up my system around the Susvara and I think it is just about right.
I have demoed the Raal in my system twice now, and have decided to go ahead and purchase it (traded with a dude from Canada who is taking my ZMF Verite in exchange).
So I'm aware of the sound of the Raal and, with all else "equal and optimized" (or so I think..), the only other component which I do not have yet are the speaker cables. And since I have to purchase a set of speaker cables no matter what, I'm taking this opportunity to try and get a set with the "warmest" sound possible.
On a side note, I've really no issue with folks saying that cables can't sound warm or be used as tone controls etc. Everyone is entitled to their opinions. I figure, no harm trying. If anything, expectation bias and placebo do definitely exist as well, but as long as it manages to increase enjoyment of the hobby, I don't see why not too.
