I will add that my BPT 3'5 Signature plus unit is silent in my room. As @sns mentioned, this is likely a reflection of stable AC voltage coming into my home. It has been one of my best audio equipment purchases over the years.

Is an isolation transformer better than a power conditioner?
I was never thrilled with my Shunyata Triton/Typhon pc.
It improves the SQ but not dramatically. And it is two large chassis that take up a lot of real estate. And not particularly attractive. And we’re $18K new! One would expect transformative performance.
Just went to great lengths and expense to run a dedicated AC line. $4.5K of special Oyaide cable, duplexes and cover plates. And $1.2K electrician.
It was also highly recommended that I also go with an isolation transformer. Went from Torus to Bryston to Equitech. Focusing on the balanced power Equitech.
Getting one, I am curious to know if it will “blow away” my T/T as I have been told.
And with the dedicated AC, maybe not plugging my amps into the new duplexes but the Et would be better. Or plugging in the Et to the T/T and the T/T into the wall.
But I sure would like to get rid of the Shunyatas.
