I've been trying to find some information on the frequency response of the HE60/HEV70 system, along with any reviews.. Just for something to read about whilst i listen to my new set. Google didn't throw up much but it did bring up this review
http://www.hifichoice.co.uk/archive/...rintreview.htm
from the mid 90s i think. One bit in particular interests/concerns me

What do people think of this, could they even try to explain it a bit clearer as i don't really know what rapid phase shifts or high-Q resonances are
I've not heard anything untoward as yet.. if there is such a problem had bad is it, what recordings (CDs?) show this up, and is it a physical resonance or an issue with the HEV70 doing the driving?
Cheers

It's the treble that betrays this Sennheiser, being less refined than that of Sony and Stax rivals in this comparison. There's clear evidence of a very-high-frequency in-band resonance revealed as vocal sibilance with some performances, and as a phasey edge that can be detected with many recordings - rapid phase shifts are associated with high-Q resonances, and the audible effect can be a comb-filter type of phasiness. The effect lent an uncomfortable edge to Jennifer Warnes's voice, and a squeaky, slightly metallic overlay to orchestral strings. Percussion suffered most, sounding coloured and coarse. |
