Our mission is to make sorrounding reality inspiring for eyes and for 
ears. Our goal is to offer novel, luxury things – things with a bit of 
creator’s soul as a contrast to pervasive trumpery and mediocrity. Using 
those special things shall be inspiring and nice. Our inspiration are 
audio and automotive worlds seemingly outlying but in fact having a lot 
in common. When you read about our turntable design you will notice 
it clearly.                                                                                                             
So, relax and spend a while with us…
