I see that you don't believe that the energy put out by a loudspeaker can cause damaging mechanical feedback.This is not what I said.
Air-borne feedback can be absorbed into the structure and transformed into Structure-borne feedback which is most damaging to the analogue chain.
What I am saying....is that a turntable system......properly isolated from Structure-borne feedback will not have its performance affected by Air-borne feedback.
If you claim that Air-borne feedback adversely affects the sound of the turntable.....then it MUST increase this affect with increased volume.
There are no ifs or buts or maybes.
This is a logical as well as scientific corollary.
If this corollary can not be heard......you simply have no evidence on which to substantiate your claim.
If there were any doubts left?........listening through headphones would provide untainted and fully complete information unavailable through loudspeakers at any volume?
This has not been proven to be true in my system on any occasion.
If air-borne sound transmission were an issue......a high-res direct digital transfer from a record would sound better than the actual record itself when played back through loudspeakers?
Michael Fremer has conducted many demonstrations of this with actual audiences....and the results are in fact the reverse.
....is useless to ignore something that exist and ignore it because we can't here it.This is surprising to hear from you Raul who always insists on 'evidence' and 'science' in other audio arguments?
Can you please explain to me the difference between something NOT existing and something EXISTING.....but undetectable....as it applies to audio?
