Powered speakers show audiophiles are confused

@donavabdear hate to ask a dumb question, but the buzz does go away when you disconnect the audio input to the sub?

This thread started about powered speakers and confusion. I see a LOT of confusion in the last few posts that might derail this thread.

You don’t need tubes, power bars, exotic setups, multiple systems, and on and on people. The point of this thread is the advantages of powered speakers, not the confusion running amuk among the multiple posters here.

So look, let’s get down to it. To get a GREAT result for a very reasonable cash outlay here is an example. Two active speakers plus one preamp/streamer with built in room correction. That is all you need to get a great result. Don't let the confused posters make this complicated. Not your problem and certainly not mine.

I took two Paradigm active speakers plus one Paradigm PW Link preamp (entry level) and BOOM. Notice how flat the graph is even before the room correction. That is due to a large part of the engineers success building the speaker. I didn’t need to stress about amps, cables, yada, yada, yada. This setup would work great for a big room, an office, a bar, etc:

OP, did you try hooking the Genelec's up to the Lyngdorf yet in just two channel? 

I'll bet it would be an eye (ear) opener if you compared the measurements of the Paradigm 9H's with the Genelec's in a stereo setup. Can Room Perfect print out a graph like ARC can?

@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
