Good News! Soon i get Sleek hi_freq filters and will made new our Russian Sleek custom models!
For now.
Recive customs from Sleek and compare it with my version
Can say next - smal version sound like hi-end monitors. Sound some differend from official Sleek customs (description - later). Main difference - small version is to exact, neat, separate like real monitors. No coloration at all. Bass is so accuracy ... i never hear it before. May be no so poverfull like many people like but beter than ever i hear before. And i hear all best IEM what we have in the world i think.
IMHO - Sleek audio make best armature driver in the world. Nobody make enything even closer. Realy think with drivers from sleek and with filters aberybody can make enything...
So - waiting for omponents and will make something else
Then i get filters will think how use it
