Tube microphonics


Hello. I am using Audio Research Ref 750 mono blocks and they in front of my speakers but off to the sides. Someone told me on another site that if I move the amps beside the speakers and not in front of them , my system will improve immensely. It will reduce tube microphonics. What are your opinions of this and I just want to say that I’m very new to tube amps so this is something I never heard of before. Thank you all.

If you think about how nearly all loudspeakers radiate bass pressure waves, then it really shouldn't make much difference if the power amp is behind or in front of the loudspeaker as far as exciting tube microphonics.

@onhwy61   I was thinking the same from the very beginning too. Plus my speakers are B&W 800 matrix. Top and bottom bass also. They act like having 2 subwoofers on ea speaker.

                            And: you were correct.

       ie: https://upscaleaudio.com/pages/microphonics

 

 

     Keep in mind: parked next to your speaker systems, your amp's entire chassis will be boogieing, in tune with the music.

    How much time, effort and dinero, have many of us spent, in an effort to eliminate undesirable vibes, from our components' (passive/active) electronics?

          Of course: one's listening habits (ie: SPLs) would be a major variable.

                                               Happy listening!

Arc puts damping rings only on the smaller tubes  (In my case they’re 6922’s.) for a reason.  They are the most sensitive to microphonics. Having said that,  all tubes are subject and it can’t hurt to try tube dampers on your other tubes.

All the best.
