Today, I was in the "big" city and had some time to spare. I thought, why not go and have a listen to the RS-2X and RS-1X, which I had not listened to yet. The dealer told me they stopped having RS-1X in stock because they often had it returned from consumers, who purchased them online and didn't like their sound. "Simply too far away from what people expected" he said and a headphone that split the waters. I can only imagine that they must be super bright compared to other headphones. Maybe the "Etymotic ER4S" of Grado's? A headphone that you really need to spend long time with to adjust your ears to appreciate the bass compared to other headphones.
So, from the reference series, they only had RS-2X in stock and I spent some time with them playing from a VIOLECTRIC DHA V226. They looked stunning with the beautiful bright wood but they didn't really convince me. I found the treble somewhat incoherent with the rest and they didn't sound natural. They excelled in micro detail and air but sounded thin and lacked some of the kick and edgy punchiness that I have gotten used to in my SR225e. I know that quick judgement should not be ones final decision on a headphone, but they are indeed different from what I know as the normal Grado house sound.
Since I was not impressed with RS-2X, instead I asked if I could try the SR325x. Earlier I sold the SR225x because I liked the SR225e better. My thoughts on the differences between SR225e and SR225x are written here:

Immediately I was impressed with the SR325x - WOW! Such a punchy, open, coherent and in your face sounding headphone. Really balanced and natural. The pairing with VIOLECTRIC DHA V226 was divine! I ended up purchasing the SR325x... took me 5 minutes to decide that I couln't leave the store without them.
Right now, I find the 325x better than the Hemp to my ears. Whether it will replace the SR225e as my Grado reference, time will tell. I feel like I could build my end game system around the SR325x.
