I'm not thrilled with your list, and have you had a chance to listen to any of those speakers? The amplifier you have acts like a pure voltage source, and I think it sounds great. I was going to suggest a list, but @freediver beat me to it. The only other speaker I'd add is ATC; any model that is in your price range will open up nicely with the Simaudio amp. I am intrigued by the Bamboo cabinet speakers(Ascend Acoustics) that someone here recommended. I never heard of them until today. I have a different philosophy about audio than many here; I'm not interested in hunting down every possibility, combination of equipment out there. I have little respect for 99% of reviewers out there, 100% of the YouTube influencers; a waste of time outside of entertainment value. Most, if not all, of these players have some vested interest in pushing product, and they likely have not heard much of the competition. If there is no local or at least not too far dealer where I can listen to a product and get help with service, advice with real product familiarity, plus support down the road, I won't bother with it. There's always going to be something better down the road; it's inevitable, and the idea is to be happy in the now, or go nuts thinking about what you might have missed.
