The horns are still plugged but I desired to test if the vibration from the midbass hors will be detectable on the listing room floor. The mouth of the horns does vibrate. Well, it is not a vibration but rather some shaking – pit in this way – if I hold my hand on the mouth then I do feel that the horn operates.

So, I desired to play it at full throttle. I maxed out my preamp and played a fragment from Queen of Spades. There is an episode in first act when a ghost comes to Countess and predicts that she will die when a yond lover will force her to reveal the magical secret of the Three Cards. As soon the prediction stated the orchestra dive into a magnificent fortissississimo, the whole orchestra with drams, brasses and strings introduce the hit of fate and then hold it for a while.

I played it a few time and was trying to detect if anything will be sensing on floor. It looks like it was free from any bone-transmitted vibration. So far so good. If it behaves like this without the throat plugs then my concerns are not warranted.
