I think my main concern is to chose the wrong one, I would probably be happy with either one of them but still. It's leaning towards the UM Miracle or ES5 for sure, tho I have looked at some of the less known companies such as 1964 and Hier Audio. Anyone with experience with their products, such as the 1964-Q and Hier 6A?
Hi there, keep in mind that the part I bolded may not be true. People have been unhappy with high end customs because they don't match the sound signature that they want. For example, even though the UM Miracle is surely very high quality, a few people have bought it and been highly unhappy with it because they were looking for a warmer, fun sound. The problem isn't the Miracle, it's that people thought "oh even though it's not what I want it'll be so high quality that I will like it". That wasn't the case.
You should write John Moulton, the wizard audiologist behind Heir Audio (his email is in the heir audio threads or the heir audio website) about the 6.A. Everything he does is very well crafted, just tell him what you want to hear and he'll let you know which of his custom line is right for you.
