Hi Guys,
Long time - no see!
Just had the chance to listen and check out the new Orpheus prototype at the fair in Austria named "Klangbilder".
First of all I want to thank you the guys of Sennheiser to give me that chance!
However as this product is really placed at the top end - I want to be very critical, even it was still a prototype.
To my impression, the DAC, Amplifier well placed in an solid Marble stone is really great!
Sorry, I do not have better words for it! If I would find it in my brain I would use - really!
As an acoustician and former headphone and microphone developer of course, I tried to judge the headphone itself much more than the amplifier.
Please understand that there was limited time only and may be a lot of my following comments are a result of this fact.
To my impression, the maximum sound pressure level where the headphone does not have too much distortion is relatively low.
Low means...: I checked it out with approx. 110 dB SPL (no filter!) and with simple music like Dire Straits it started to become distorted. I mean with simple music not the music itself, I mean the Crest factor. Or in other words it's not a music which force headphones dramatically.
Another impression was, that the sound stage - or may be better - the spatial imaging was also not really great.
Of course this is wailing at a high level, but for about 50.000,- € !!??
Just before I got the chance to listen to the new HD 800s... My impression it offered a larger surrounding.
Also the fit to the head was at least to me not at that level which the HD 800 offer.
Ok, enough bad criticism:
What really is great and may be more than great was the overall acoustic balance to my ears.
I never had that experience before!
All instruments sound naturally. The impression is really great and no other headphone offered it at that level in the past.
Nobody will have the need of any sound correction by equalisation or so! The air volume between the membrane and the human ear is large enough to be sure, that individual ear sizes will not change this impression.
Overall a really great headphone! Please be reminded that I criticise on really high level based and related to the expected sales price.
On the other hand, the product is still not on the market and may be, my critic could give Axel Grell and his team at Sennheiser the chance to adapt the next sample runs a bit.
Best regards,
Heinz
