@ESL-1 would love to know how you first heard about Grado headphones in those early days (no internet, no headfi, no advertising). I was at a dealer in 1991 and he recommended that I try a pair. That was the start of a journey I'm still on today. I still remember the HP2 with the Melos SHA-1 as being a great system.
I was an authorized dealer for Grado so was there at the beginning when Joe Grado designed their first headphones, the Signature HP1000 series and sold a good amount of each of the three.. When Joe retired John took over the business. One of John's first headphones were the original RS1. I bought my pair right after John had decided that with the escalating cost of the wood presentation case was becoming too high. That was when he started to include his 15' and 6.3mm female to 3.5mm mail pigtail with the RS1. That tradition is still in effect today. John includes those accessories with all his upper end phones, not bad as that is a $55 value.
They more recently now offer a option of a very good looking wood presentation case at a reasonable price.
The Melos SHA-1 was developed with the HP1000 in mind so they were a superb match. I have an HP2 and the Melos and they really have great synergy.
