Buy High Pass Filter or KAB RF1?

Gotcha thank you Al. I ordered the Atoll today from Canada. I figured it was worth a try because I have never heard magic before like what comes from my Atoll amp. I figured they must know what they are doing to some degree. You would know better than I, but my experience so far is that more expensive may have a better chance of being better, but more expensive doesn’t always mean better. I think I have said it before but my $4500 Anthem A5 sucks! Lol

Very well said.  I concur 1000%.

my $4500 Anthem A5 sucks

in your opinion in your system. Could be the cat’s meow in another's

Indeed ieales, indeed. I’m going to try the Anthem as driving my Atmos and surrounds in the theater room I am building in the basement, and use an Atoll for the fronts down there.

I also have an Atoll upstairs for my record player driving my two Monitor Audio Golds. Soon I will have the Atoll phono preamp.

I have two Marantz AV7704s, one for each room.

As Al rightly said, the majority who suggested an extension of the phono cables as a test did NOT suffer the hum you describe, or obviously the suggestion would not have been made!

And I do believe the majority suggested as a test not an ultimate end of game fix.

But I will admit I have never owned a Rega so unsure as to how that would have reacted in my system under the same circumstances.
Neither of my two JVC DD tables had any issues with phono cable extensions for testing.
