Equitech Son of Q vs. BPT

What is the general consensus regarding using these power isolation products. Usage would be for phono amp (Aesthetix IO Signature) and preamp (Octave Jubilee) on a 20 amp dedicated circuit. I think I am sold on using these types of products for my most sensitive components and only wish to address power isolation. I use Isotek Gemini power isolation strips for all AC duties except for the amps which are plugged into the wall directly. The wall outlets are Teslaplex SE Cryo.

My goal is to ensure that I am ridding any external pollutants which may enter into the source components and also to protect from voltage spikes and noise at the same time. From what I have read, I am being swayed more to the Equitech Son of Q Sr (20amp) power isolation transformer.
Thanks in advance.
