For stands, I have these and find them to be solid
https://www.bestbuy.com/site/bowers-wilkins-stav-24-s2-speaker-stands-pair-black/1197018.p?skuId=1197018 I bought open box 'excellent' condition, ended up being a customer return having already filled the stands with something. Felt bad for the delivery driver.
Have also heard good things about these:

Using them with Focal 906 (bought during the current sale). Also chose the SB12, haven't really had a chance to use it yet, waiting on my tv to arrive (although I did look at the SVS Merlin tool and they recommend all three sealed, ported and round).
I was talking with David from Ascend about Sierra 2 vs Towers in my 11'x14' room with seating 5'-6' away and lower listening (apartment/neighbors), and he said that while the midrange/RAAL is better in the towers, the additional cost vs the 2's might not be as worth it. I appreciated the honesty and do plan to try them at some point (had originally planned to audition both Focal and Ascend, but living in a studio apartment, I forgot how easily it is to get overwhelmed by cardboard boxes).
