I'm always looking for new stat phones and found that in Russia they are manufacturing excellent electrostatic headphones wich reach TOTL status.One example is Phenomenon Libratum and Canorum with new V3 drivers, both are at least in my opinion better than any Stax out there, of course Stax mafia doesn't agree with this. Recently i found another brand Perun wich have two models one bass heavy and one "normal".They are made in Yalta a diy project . DIY Perun headphone has been around for about 10 years ,and this is the latest incarnation of it.I have followed the development of this phone on the russian forum for years and unfortunately the thread where it was introduced was deleted.This phone has gone through many stages and many prototypes ,even tens of different pads were tested.Every corner of this phone has been investigated to reach best possible performance.In it's latest version wich is the last and final version is comparable to the best stat phones around,many prefer these over Orpheus and SR-009.The driver is about 50% larger than 009 and is very efficient and easy to drive.This DIY project has gone now commercial http://perun.prfi.ru/. So I got recently the Perun headphone and gave some "run in" hours. The looks is great,this is truly the electrostatic Grado very lightweight and comfortable.So far it's sounding very promising ,quite neutral with old Stax Omega 1 "touch" on it with similar soundstaging and imaging maybe with cleaner midrange.It's quite neutral and "naturally" detailed where i consider 009 to be neutral but unnaturally detailed.Perun has a very quite background and somebody may think it's dark sounding but it's not .I can hear a bit of old school Stax sound here (Sigma) but way more dynamics First hour of listening says that we are dealing here with a world class sounding headphone . The midrange is likely the best i have heard from any stat before,it's huge,very musical,voices like female vocals are stunning,the sound is BIG / transparent and envolving,but it isn't euphonic it remains still neutral and balanced.Perun has warmish tonality quite different overall than any Stax maybe towards HE-90 but it has it's own sound wich is very compelling. Was fiddling with the drivers and headband i don't know which way i should have to use them but tested vice versa and ended to find out that it has significant impact in sound quality how to use them. The sensitivity is close to Lambda models with means these are easy to drive.The construction is very comfortable / softish and very lightweight so you can spend many hours with them.Bass is on the level of better Lambdas and highs are smooth and detailed and never tend to harshness.I find that best sound level to drive these headphones are lower volume to average volume, i would not drive these phones on high levels ,not needed,Peruns are likely best with classical/vocals ambient ECM jazz recordings. The transaction from Russia to EU was smooth with great communication and zero problems .The asking price 1000 USD is very low considering build quality and performance.
