HIFICHOICE上SENNHEISER HE60/HEV70的评价:
The HE60 and HEV70/UK combination - the former a headphone, the latter a mains-powered energiser - is derived directly from Sennheiser's £9,600 Orpheus, but is simpler and more affordable. The headphone is still electrostatic, but its electronics are of the solid-state rather than vacuum-tube variety, though they run in Class A.
The HEV70/UK preamp is fed by a line-level input from your system amplifier's tape output (or similar), and is equipped with a friction-coupled dual-concentric volume control from ALPS. The only controls are a signal overload/power telltale and an on/off switch. To preserve existing tape loops there are both line in and output sockets.
The HE60's large electrostatic diaphragm is protected by a steel mesh cover internally, matched to an open-back enclosure fitted with firm oval circumaural earpads. A comfortable felted material covers the latter keeping one's head reasonably cool. The headband is a simple padded hoop, which is comfortable but no match for those of the Sony and Stax models. Cable length is 2.9 metres.
The HE60 and HEV70/UK combination is almost twice the price of any other model in this test, and by comparison with them it was disappointing. The open, pure-sounding midband is not bettered by any of the others in this group, and the frequency balance, very similar to the Sony MDR-CD1700, is light, open and agile, with a suggestion of treble lift. The bass is excellent, though lacks the authority and weight of the much more expensive Orpheus.
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.
The good news is that the resonance identified was limited strictly to the treble. There was no audible consequence in the midband, which seemed completely free from coloration of any kind. In the main, the Sennheiser sounded precise and articulate, with excellent imaging like the Sony MDR-CD1700 but with a much greater feeling of overall depth and spaciousness.
