Power Conditioner/Surge Protector Options

I have not listened to my system with a TrippLite, except for the subwoofer.  Couldn't hear a difference. 

I used to live in a variety of dense apartment complexes though and I can say I could hear if the Furman was out of my system. It never sounded quiet enough or smooth enough without it. I use two now, one for the video stack and AVR, the other for the audio stack.  Maybe I need to be a real loud bass head to hear it but I've never heard any lack of dynamics. 

Triplite and Furman are certified and tested to UL 1449 standards as surge suppressors.  Check whether or not the Audioquest is UL 1449 certified.

The Triplite and Furman use different noise reducing technologies.  Furman's is more advanced, with LiFT added to the SMP.  The Triplite isolated banks have known weirdness:

Audioquest units try to excel in the audio domain by adding a lot of inductance in series with the power and ground wires.  I don't know how that translates to audible improvements.

So, my suggestions:

• Use the Furman with LiFT and SMP for the best noise and surge suppression.
• Use the Triplite on all your other sensitive electronics (routers, PC, bedroom TV, laptop chargers).
• Use a surge suppressor in your service panel, which is now required as of the NEC 2020.
• Use boutique, un-certified conditioners only if you don't really care about surge supression.
