Headphone no cost limit.

I'm not a headphone aficionado however I was taken by , couldn't hardly believe it , a Chinese manufacturered preamp headphone combo by Ag Audio the HE -9 model ,.I think if I remember this is one of their flagship models . I made note of the model and later found on their site an impressive mission statement ,..It ain't Chinese junk ,.....Anyway this was paired with Audeze headphones ,their top model ? Source were Esoteric player, model ? and a Accuphase T1000 tuner ,.Very , Very impressive..

thank you all 

IMO the world's best headphones is the Hifiman Susvara when driven by Viva Solista speaker amp or even Aries Cerat Genus integrated.You have to experience the Susvara driven by speaker amps to know what's possible with this headphones.

I have had the fortune to own about a dozen different cans at the moment, but I have not heard the super expensive $25+k headphones, but can say most under $10k.  I have probably owned 25 different cans over the past 10 years, bought, sold, traded, etc.

Well, my head rig sounds great to me, but it’s about tube rolling & synergy. Having a great source and then a sensation rig can allow your cans to really shine in a way you never thought possible. Growing up in the 80’s I had some electrostatics that had great mid/high detail, but lacked in bass.

After several different rigs, I have settled on the Woo Audio WA5-LE, but with vintage western electric or newer takasuki 300Bs with vintage 1940’s tube fed by a Modwright/Oppo transport (with vintage 1940’s tubes) now sounds sensational with focal utopias or Abyss (modded with moon audio black/blue dragon cables) surpasses many sound systems I have heard at the shows. Enjoy the music.
