Well, this is my first post ever and I've been a member for quite a while, I have read countless of threads, I did not post before because I was focusing in finishing college, none of my friends are interested in music like me, they are but spending more than $20 on a headphone is crossing the line for them, So if you decide to meet someday to check our gears let me know, I currently own Custom made Heir Audio 4.A and 8.A, and my sources are a Sony Disc-man D-25 regarded as the best sounding portable CD player ever made and a Panasonic SL-C470 also regarded as on of the best of the early 2000 both of them with line-outs, I had before the Seinnheiser HD800, Bayerdynamic DT1350, and ultrasone Edition 8, they were all driven by my Onkyo receiver, which I know some of you will say that they were NOT supposed to be driven by a receiver but they sounded good to me, I sold them to get the custom i.e.m because of portability issues and people getting mad because of the sound leakage, but know I am interested in buying a full size can again, I am from the Miami area, zip codes 33125, 33172, 33010, 33012....you get me! and by the way I am going to write a review with pics about my Heir Audio ciems now that I have some days off!
