Poniżej wpis własiciela HD600 rekablowanego Cardas\'em który po raz pierwszy usłyszał słuchawki ortho
"Hi all.
A couple of weeks ago i was lucky enough to listen to three sets of Kabeer\'s orthodynamic headphones, Yamaha HP-3 and YH-1000, and Aiwa HP-500. These are the first orthos i\'ve ever heard and as suggested i\'d like to give you my impressions of them.
I only listened to them for a couple of minutes each as a direct comparison to my cardas cabled Sennheiser HD600s, but it was enough for me to form an opinion of them. Source was FLAC files into my Aune DAC though Kabeer\'s Cavalli CTH (which i now own).
Suprisingly I found all three sets to be noticably more natural sounding and effortless in their presentation than my HD600s (which i\'d considered to be the most natural sounding out of all the headphones i\'ve heard), and were not obviously lacking against the HD600s in any way i could hear, which suprised me. I was expecting some drawbacks from an old design that never caught on but they didn\'t materialise.
Specifically i found the HP-3s to have a very polite nature and to be well balanced tonally, what i would call a very neutral sound but without sounding dull. Simply better than my HD600s.
I found the Aiwa HP-500 to have a slightly fuller and warmer sound then the HP-3s, but with a little resonance in the upper bass which was slightly off-putting, may even have been due to the pads but i\'m fairly sure my ears would adjust after a little while with them so i wouldn\'t expect this to be a long term problem.
The YH-1000s were back to the neutral sound of the HP-3s but were fuller and airier, and had more life than the HP-3s, but i also detected a slight resonance in the lower mids, something only noticable when listening critically, the music is simply to enthralling to be bothered by this in use.
What this exercise showed me was that orthodynamics are a step further towards the live sound i chase than my HD600s, and i suspected at them time i wouldn\'t be buying another set of dynamic headphones. Since then i\'ve put my money where my mouth is and this morning i was lucky enough to take delivery of a pair of unmolested HP-3s.
Thanks Kabeer for introducing me to the wonderful world of orthos!
From memory they don\'t sound the same as Kabeer\'s, which i believe are modded, but right now i\'m enjoying them to much to be critical and think about how the sound could be improved, and i\'m going to make the most of that enjoyment while it lasts!
It\'s also occured to me that although i\'m all for technical advancement i\'m just about to listen to 200 year old music on a 30 year old turntable, on a set of 30 year old headphones through a tube.
I\'m not as modern as i thought...
I was planning to read through this thread to get some idea of how to make the most of these headphones, especially the use of a power amp to drive the headphones as mentioned above, but over 900 pages this could take me a while! Can anyone sum up what i need to know or point me towards key sections in this thread please? Thanks in advance"
