Powered speakers show audiophiles are confused


17 of 23 speakers in my studio and home theater systems are internally powered. My studio system is all Genelec and sounds very accurate. I know the best new concert and studio speakers are internally powered there are great technical reasons to design a speaker and an amp synergistically, this concept is much more important to sound quality than the vibration systems we often buy. How can an audiophile justify a vibration system of any sort with this in mind.

I don’t think I can go active, other than the subs.

Then this would clearly be the wrong thread to get suggestions. If you change your mind and decide to go active, just post and I’m sure you will get some good recommendations.

You already have a SOA active system with the Genelec’s so I get wanting to dabble a bit.

@donavabdear , apologies for not ignoring the man child. I will try better.

Had heard a lot about the PS power plants, but never dug very far into them so read a bit and talked to one of my EEs. The PS units are not true isolated regens so that may be why they don't solve it. Odds are good that the extension cord is getting you onto the same phase as your other equipment. Shouldn't matter, if you can, plug everything into a single phase. Easiest way to test is plug everything into a single power bar. Just don't turn it loud and you should be able to test.

@invalid , a page or so back, I posted what Stereophile measured for SNR, 90db on balanced, but that pre-amp has really high output and they may have measured that 90db at the full output level. At a normal level, it could be 10-20db lower. That would be audible. The unbalanced are even noisier.

 

@thespeakerdude  I don't think that the BHK preamps are consistent from one example to another, some people claim no noise and others have a lot of noise. They didn't all have high sensitivity speakers either.

No worries, I don’t think you could get any worse. If you ever get some actual speakers start a new thread so we can celebrate OK?🙄

LOL, this guy will lead you from one dead end to another, feel free to play around, just don't spend any actual scratch.

 

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