I happen to own a buttoned RS1 from the same era as well as the GS2ke. I also have the HD800 in house though it isn’t technically mine. I’m not a classical guy; I do have a few movie soundtracks and a lot of ambient music. I listened to stuff like classic rock, blues, new wave, reggae, punk, 80s pop, old school hip-hop, late 80s country, heavy metal, shoegaze, grunge, industrial, progressive rock, electronic, trip-hop, post-rock, and modern metal.
Some impressions
I’m at 20 hours on the GS2ke, and so far the midrange has such full bodied instrument and vocal clarity. It’s almost effortless to pluck out instruments and follow notation. The timbre is rich and lush yet immensely airy. There is superb depth & instrument separation. The way it presents all the layers in strings, vocals, and keyboards is amazing to peel back in awe. The vivid lifelike open presentation still gives me the chills down my spine!
The tonality is a lot like the GH1. As @ESL-1 said, the GS2ke does every bit up the ante on the GH1’s sound profile. It is an even tonality that is very natural and analogue like.
Decay is among the fastest and cleanest. The transient power is just right. In the last 6 months, I’ve never felt this drawn into the music before. It is so transparent; it can be both emotionally and analytically engaging depending on the music.
Bass is still developing, so far it’s tight, clean, and controlled but doesn’t quite have that “slam.” It doesn’t extend very deep; instead it rolls off just before reaching the bottom. Nevertheless, sub bass rather exciting. I look forward to hearing the improvement in the bass.
I do get an awesome bass drum kick with very convincing “you are in the drummer’s seat” presence. What the treble may lack in impact most certainly makes up for in the details. The refinement of the drums is quite beautiful and exactly the sound I prefer. It’s fast, natural, crisp, and oh so airy without being forward or rolled off.
How the GS2ke stacks up
The sound is the merriment of the HD800 and GH1 together. The HD800 balanced on some Telefunken tubes sheds off the hot treble and sibilance others complain about. With that in mind, the GS2ke shares the same strengths in tonality, clarity, imaging, and soundstage width. Almost the same thing can be applied to the GH1. The scale is just bigger and more textured on the GS2ke.
The PS1k is the undisputed bass champ. It still has the most impactful treble without being hot. The buttoned RS1 is the most intimate acoustically and vocally. While it is scaled down pretty small, it makes up for it with arguably the most emotionally engaging sound profile in stripped down recordings.
The GS2ke is the best all around Grado I have. It certainly is a genre master. It doesn’t shine on any instrument over the other. No matter what I throw at it be it good or bad quality recordings, it does the material faithful justice.
It’s probably too early to call it, but this may very well be “the one” for me.
Balanced versus single end
These impressions come from about 75% single end and 25% balanced. When listening balanced, I noticed the soundstage gets a little bit wider and imaging is at its absolute pinpoint best. The midrange evens out a little more and the background details really pop out. On single end, the midrange pinches slightly forward offering a tighter presentation.
Note on the low hours. I’ve had these over a month, and work kind of got in the way. On the side, I’ve been upgrading to cleaner power with conditioners and hospital grade outlets.
