FWIW, the Poiema is great, and so are the Silver Audios. The SA's are faster, more open, and to say they are "bright" was not quite the right word in my system, but yes, they aren't laid back and "warm." When I think "bright" I think Nordost Red Dawns, if that helps.
The problem I ran into when I "Poiema'd out" my system is everything became *too* smooth. Robert at RSAD gave me some ideas for fixing the problem, and I may go down that road in the future, but not just yet.
Good news for you is that resale values for both these cables - unless you must have the latest iteration of Poeima - is ridiculously low here at a'gon right now. I've been trying to sell my RSAD speaker cables and SA Jetstream IC here for a couple months, even taking sizable losses over what I paid for them, but to no avail. You should be able to strike a great deal on either (I'm speaking generally here, not pitching my own gear, I promise!) if you want to try both.
Both are remarkable cables, and I would venture to say that one of the two will be a keeper in your system for a very long time.
Good luck in your quest.
