With power conditioning, there are a million options. The best one I am familiar with in this price range is the inakustic at $3K. Incredible filtering and one of the better units, regardless of price. The issue is that the power cord they recommend with it is more than the conditioner, the AC4004 20 A runs between $3250 and $3750 depending on length. If nothing else, you need a serious, 20 amp power cord to feed this.
Aduioquest's Niagara line is very, very good as well. They argue that it will be at its best when all cables in your system are AQ as they use a unique grounding system which is what they feel is a major culprit in terms of noise in most systems. The Niagara 3000 is $3K but again, a power cord is extra. Something like a Thunder at $850 for 1M would be just fine. The 1200 is nice in terms of filtering but lacks the power reservoir that the 3000 and up have. It is $1000 and you would need a power cord as well.
Finally, check out Shunyata. Unfortunately they took a price increase at the start of the year. The Hydra Delta D6 is great tech. It was in the sweet spot in terms of your budget and is now just above it at $3250. It also needs a power cord.
I sell inakustic and Audioquest. I have no relationship with Shunyata. I just happen to know it is a good product.
