Welcome to this thread. Why am I starting it? Well, I looked for a Grado RS-1e thread and didn’t find one… just a few people selling them. I am currently an owner of a pair that I ordered as an RS-1i and discovered that what I actually received was rather different: headphones marked RS1 on the cups with a 1/4” plug and red drivers. Further investigation, including some measuring, revealed that I actually have is an early “Frankenstein” RS-1e. When I first received them, they sounded shrill, bassless and boxed-in. They distorted with large ensembles playing loudly and were, in general, hugely disappointing. I played them in for 100 hours and tried again. They were improved in all parameters except the tendency to fold under pressure of loud ensembles at loud volume. I relegated them to a secondary set-up of Mac Mini feeding a Meridian Explorer for a while. I used them on and off and, one day, I found myself enjoying them. Result - I am bringing them back into the fold and giving them some love. I hope that this thread will enable us to share experiences and enjoy the insights of the Wise (those folk with all the Grados and the right kit to go with them). Over to you.
