I received my Merlin on Thursday morning, after using it for 4 days; I decided to post some experiences. The Merlin took two months from sending the impressions to turning up on my door steps (minus few days of delay while I changed my mind on the order in between). The communication I received was 1st class; there are some horror stories on dealing with certain company representing UM Lab here in the UK. I made my order though Stephen Guo from Custom-iem.com. There were two dozens of emails sent between me and Stephen, he replied to all of them either on the same day or the day after, consider the US is over 8Hrs behind the UK, I don’t think you can ask for more than that. The Merlin fits perfectly, this is my 1st custom made IEM, so I don’t have any reference to compare with. However, it fits conformably; it’s not loose and has great isolation. The sound, WOW, it put my IE8 to shame, I cannot believe I use to think the IE8 is a top class IEM. The Merlin also gives my HD800 a run for its money using the same DAC and amp, I think I prefer the Merlin with live performance, can’t stop smiling watching Stevie Wonder Live At Last. P.S. I took some photos of the box and the carry case compared to the case from IE8, I put them in my Avatars folder due to poor quality from my lack of photography skills and cloudy weather here in London.
