Thank you for reply lojay. Is difficult to understand for me the difference of price between Angie and Lyla, $1400 is a big difference for 2 iems with same or similar science and technology. I know A&K products are very expensive and market always say how much money people can want pay but is strange. Angie isn't cheap but isn't shock price like Layla. Maybe Layla can cost $1500 or $1700 I understand more. I want Layla with ak240, it says is good combination sound the reviews says because iem is portable but sometimes I use iPhone 5S. I watch people say Layla is best iem and compare to expensive headphones. I think sometimes bad opinions is people cannot pay $2500. Very honest review is difficult finding but I wait more opinions from experienced people. Yes, is true is important to live with equipment to give opinion more real. I want to try Layla myself but is not easy, maybe I like it but not very very much, if I don't like it very much is very much much money. Angie maybe possibility buy now but I want sure and don't think after I make mistake with Angie.
