Holy mother of god these headphones are leagues above any headphones I've ever heard before. Like, if we keep it to closed backs, these run LAPS around the Stellia and the Liric - open-backs wise, they made the Arya Organics feel like it's soulless and the Meze Empyrean 2 like it's a smudge of colors, for god's sake. I know tuning plays a big part, but it's SO ON POINT. Thanks a million John. You just made me my dream headphones. They are perfect. - Matteo
Headfi member and owner of the XTC- "I've played piano my whole life and I have been tested with perfect pitch multiple times. Piano is very hard to record and takes some incredible stuff to sound right. My 'reference' Focal Clears are the equivalent of eating plastic when you ordered pizza compared to these here and I LOVED these things. I have never heard piano sound correct until the XTC. It is just like wow finally. I can't believe how fake piano sounds in 90 percent plus of recordings and I had just accepted that as normal until the XTC. I would not be surprised if the beryl XTC was the most precise upper mid bass headphone in existence. I have just began testing the biowool on my new system and WOW it shines on there too. I did an all out double take yesterday when I swapped to the biowool. It is so intense, mind warping layers for your brain to re-register vs the Beryl and to AB. I2s cable + purifier with cable + nice tube wow wow wow. These headphones scaling is just unreal. I just want to AB Susvara on a perfectly tweaked system and see if it can make pianos sound like this."
