Just read your review and it very good
unfortunately the xenns up are out of my budget! I have roughly £400? The Variations sound good from your review but the only thing that puts me off is the word "lean"! I mainly listen to Drum & Bass so the Sub-Bass is very important. I have the short list down to 3? ThieAudio Excalibur, ISN EST50 and after reading your review the Moondrop Variations. All of the other people i have read reviews & opinions say the ISN EST50 is best in the low-end both in quantity & quality. Iv also had the same impressions going off reviews & opinions that the Excalibur is the best bass, it is also rated 4th in the "15 best Basshead IEM" on "Audiophileon"
Do you have any experience with these 2 IEM'S? Thanx to you and everyone else for your help i appreciate it VERY much
