I'm looking at Tyll Hertsens'
Wall of Fame : Over-Ear Open Headphones list and noticed that he's removed quite a few
expensive & very expensive ones from his WOF list including the Stax SR-009 ($5,250.00) that sat at the very top of his list for quite a while. Others include : Focal Utopia ($3,999.00), Audeze LCD-4 ($3995.00), Mr. Speakers Ether Flow ($1799.00), Focal Elear ($999.00), HD800 S ($1,699.00) to name a few. But there's one O-EO Headphone that is still on Tyll's WOF, that's been there for quite a while and that cost $399.00. Hint : it has most likely the best midrange of any of headphones mentioned so far in my post. You've guessed it by now : yep, the 20+ year old Sennheiser
HD600
In the last couple of months I decided to minimize/ simplify my headphone audiophile collection : I sold my HD650, PS1000, HD800, SR325e, Focal Utopia; sold my Cambridge Azur 851C CD/ DAC/ Pre-amp CD player; sold my Hafler HA-75 Tube Head Headphone Amp, Rupert Neve Designs RNHP, Arcam rHead & Mapletree Ear+ HD.
I've kept & this is the ironic part, my HD600, the first quality headphone I bought back in 2003 although the ones I now have are not the original one I bought. But I've gone full circle. The headphone amp I kept is the modest JDS Labs Objective2 which IMHO is the best headphone amp under $1,000.00 and the synergy with the HD600 is absolutely astounding considering the price of both combined. I listen to CDs. I went back to my Teac PD-H600 which is one of the best pound for pound (price for price) CD players ever made. Some notable reviews state that it outperforms many CD players costing 3-4 times more. In the long run I realized that I prefer it to the Azur 851C which costs 3 times what the PD-H600 did.
After all these years of buying & selling all these different headphones, in the end I still love & prefer the HD600. I'm not saying that my modest set-up is as good as the high-end audiophile equipment. It's pretty good though and with well produced music the high-end equipment doesn't produce enough of a difference in the long run to justify my years of pursuing the ideal sound any longer. In the past I've owned the Zana Deux SE, the Headamp GS-X MKII, the Auralic Taurus MKII, the Headamp GS-1 & they possess attributes that the modes O2 doesn't, that's a no brainer but how much more ? Anyway, I digress.
My points are : I'm very glad the HD600 gets recognition for being one of the best headphones ever made regardless of price, that the synergy with the O2 which to me is to headphone amps ($1000.00 and under anyways) what the HD600 is to headphones & a superbly built (all aluminium) modest CD player with a superb internal DAC which outperforms CD players costing 3-4 times more. And the sound is pretty damn good.
