Alexsee the problem is the way people compare hi-fi system
Them make quick switch between them, and choose the more spectacular one
So manufacturer always put a boost in highs (and high bass) to sell more easely
When manufacturer don't ; they have the reputation to be boring
For example Avalon Isis is told to be too "neutral" in fact it is a correctly tuned (and wonderfull) speaker
For the Indra they have boosted the highs to make it more fun
I mean an indra is still more correct than most of the speakers in the industry but it is an example to explain the thing
----
Look on audiogon 99% of people say BS abourt audio, because they don't know the correct methodology to listen a system and they have not correct audio playback to judge either
It is not their fault as they need to have speakers rent for days in their home for judging correctly
And shop rarely do that
