Has anyone compared the Denali to Audioquest Niagara conditioners?
Michael Fremer did. He didn’t do a shootout or anything, but he did switch from Shunyata to Audioquest. He was very impressed by the Shunyata but eventually tried the AQ and decided he preferred AQ. I don't know where he is on power conditioning at this point. He had a whole house power generator installed and it ruined his sound. He found that he needed PS Audio regenerators to correct the situation, but that is probably not the end of the story. You can follow what he does next in his column in Stereophile.
