Surge Protection

I use a Brickwall PW2RAUD for my 2-channel system.

They all sound like crap, which you will have to endure if you want to be prudent.

Well, here is my dilemma. I primarily want surge protection for my 14B SST (& other components as well). Seems like inexpensive surge protectors are of questionable effectiveness at best. The more expensive units generally include some type of power conditioning. Since Bryston does NOT recommend power conditioners which can restrict power flow, this creates a dilemma. I want to protect my investment, but not at the price equivalent to a great tube pre amp.

PS Audio, for example, builds the Duet ($295) which assumingly provides surge protection, unrestricted power & some filtering.
Has anyone had any experience with this product? Thank you.

Avoid. imo, the PS Audio Duet and the larger unit will pretty much ruin a system. At that pricepoint, you might as well leave it all unprotected.
