Consumer audio is rife with confirmation bias.  The only way to eliminate that problem is to use blind tests.  While true that it is troublesome, it can save thousands of dollars.

Consumer audio is rife with confirmation bias.  The only way to eliminate that problem is to use blind tests.

You've committed the logical fallacy of the excluded middle. Long-term listening will reveal a component's true qualities, and without all the time-consuming, fiddly nuisance and level-matching  of blind testing.

I use a power regenerator. All my gear is plugged into the Regenerator. Major inprovement in sound. Filters never did anything for me. Also blind testing for audiophiles is worthless. Live with a component for a couple of months playing a lot of music and you will then be able to tell if it is for you.
Blind or doubleblind testing is designed to tell if there is a difference in sound, not which is better. Did you know in a blind test if you listen to A and then to B most people will prefer B

which is why you reverse the order

of course, if there is no difference in the sound then one doesn't sound better, does it

and note, I never said to not do extensive listening sessions either...

.I have 3 Shunyata Power Conditioners.  A Hydra 2 for my amp and preamp (The Hydra 2 doesn't limit current) and two Hydra 4 Conditioners.  One for the analog and another for the digital.  All on 3 separate  dedicated lines and all Shunyata Cryoed outlets and power cords.  My system is dead quiet (Tube pre is eerily quiet) and has excellent bass slam.  I hear a big difference without the conditioners.  To me it sounds dirty without them.
