Romy,

In response to your response to what I did not say but implied....I decided to put the question here instead, where the light of enquirey might shine upon several different facets of investigation.

Firstly, I'm still interested to know if you are able to run your system 'flat'?

I would guess that the more discerning ear would have great difficulty with flat presentation of the abominations that pass for recorded music - both from now & the past.

For example, the majority of professional microphones have huge problems in the range (>5k) you describe.

In the workshop & on location I use quite brutal PA type speakers, which are 106dB/w/m horns on the top.

These are designed for 'flat' response and while though they do not come particularly close (to flat) they are not designed to compensate for upper-register distortions in microphones.

When I listen to direct-radiator recordings I find the results extremely harsh, dirty, fatiguing & compressed if I listen above a very low level.

If I had equalised or damped these 'aggressive' speakers to best suit the average conventional recording, I would certainly find my own recordings to be 'excessively dull' via the same treatment.

When I first prototyped a horn-loaded microphone, I was amazed to find that these 'aggressive' speakers were actually capable of sounding both soft & hard according to source - in other words, it was not the speakers that sounded aggressive but that they were reproducing the aggression of the source distortion in all previous cases.

By this, I mean to imply that I would expect you to have better results with my recordings if your system was run flat.

Andy
