Ido not want to insult somebodies faith, but I wanted to show you the perfect harmony between my Sita sculpture bought in Bali and the very nice KZ ZSN. I had a chance to listen to the ZSN with the a DAP, which not the most beautiful, but one of the best sounding the Astell & Kern Kann. The Kann and the KZ ZSN (price-wise the Kann cost 70 x the ZSN's price) together produced real music to my ears, and their cooperation is simply breathtaking! Try them together if you can (Kann). The KZ ZSN sounded so good with the Kann that I simply could not believe my ears However I found later my regular IEM the KZ ZS5 a bit more matured than the ZSN, but for EUR 15 the ZSN is an unbelievably good product.
