It sounds to me like what you need is not a ups per se, but a power regenerator.
As was said earlier, some higher-end ups's will provide that function, by converting the incoming ac to dc, and then converting the dc to a clean 60Hz sine wave.
Something like the PS Audio Power Plant Premier will also do that, without providing the battery backup function. But a cheapo ups will not do that, as has been said, and also creates a risk of damaging your equipment if the ac drops out.
Also, I'm wondering if the buzzing might be due to a ground-loop issue, or to rfi pickup that is specific to your new location. Are you using the same interconnect cables as at your former location? If they are unbalanced (rca) cables, and if they are either significantly longer than the ones you had been using, or if they are a different make or model, that might have increased the likelihood of ground loop issues.
And if there are any nearby dimmer switches, try turning them off as they can introduce distortion on the power lines as well as rfi.
