Powered speakers show audiophiles are confused

@invalid I suspected the same thing that the BHK was inconsistent somehow. I've changed cables AC and audio, changed AC circuits and the noise of the BHK has been the worst in the system, except for my JL Audio subs, which is another story. I replaced the BHK preamp with a Lyngdorf processor using its preamp and it was good and very quiet but no magic. I know the noise on my preamp is in the preamp because I can hear it in the headphone output with nothing plugged into the unit but AC. I believe I somehow got 2 noisy units, PS Audio offered to have it checked again on their dime, so I guess I'll give it a shot. I'm used to no noise at all perhaps that is the problem. Maybe I need to have my stereo equipment store to give me some other tube components to try at random. Thanks

@kota1 I did connect the Lyngdorf into the Genelec / ProTools system it was just fine I needed it in that system to use Room Perfect because the speaker positions were always a compromise if I looked at it as a stereo system but not from an object based system, the imaging is fine. 

A question I have in that regard on my professional system is my mixing position, I do sit much closer to the front left, center, and right speakers as does most every mixer I've ever seen. So my question is the disconnect between the mixing position doing the original object based mix and the Dolby listening chart you have posted that shows an end listener sitting in the middle of the room? Thanks

@thespeakerdude Great info on the P20s really appreciate it. Also the JL Audio 113 speaker buzz happens with no audio inputs at all. Thanks

Well that narrows it down really quick. Sounds like the subs are faulty. Found a few people complaining about buzzing JL subs (with no input) and the only solution was replacement. I think I mentioned that here or in a PM. Long extension cord is more resistance and inductance. Net effect would be similar to using the AC filters you did to eliminate the buzz. That is probably why both methods worked.

What started out as a thread about resolving confusion is becoming confusing as it is drifting off topic. Mixing positions? Subwoofer hum? Tube problems? Amps that sound like tubes but are not tubes? How to invest $200K? Problems with products that are not speakers?

Do you see why this is confusing in a thread on powered speakers?

These types of issues can be quickly resolved working with a local dealer/installer. You likely have someone local who carries both Lyngdorf and Paradigm, maybe even Meridien. With your budget that is probably the least risky, most productive way to go.
