My RS2es finally came today! I ordered them Jan 1st, but it has taken a while since they were out of stock and I am in Malaysia.
So far comparing these to the SR225e, I really noticed the bass is much more present giving more of a full weighty sound. SR225e is leaner but still very quick bass. The sound stage is definitely an improvement on the RS2e as the headphones feel like they disappear, and sound is coming from outside your ears. You can smell the wood on these which helps to complete the experience...
Treble is extended but very smooth - Classic rock tracks that are on the warm side sound great. Steely Dan is excellent - Kid Charlemagne really shows the separation of the instruments with the guitars. A great guitar solo on that one from Larry Carlton. Another classic, "Do it Again" the cymbals sound lively, and it really brings the track to life. I have heard the guitar solo many times, but not quite like this!
Even some 80s metal Judas Priest - Metal Gods - speed and dynamics of the RS2e capture energy of this track.
I was worried as I have seen some reviews that said these were not good for rock/metal, but I think the tubes help with this. Some rock/metal tracks that are already bright probably wont sound too good though.
Changing up the mood with some Diana Krall, "Just You, Just Me". This sounds like your in a live music venue. Probably one of the strengths for this headphone is acoustic instruments. They sound very lifelike to my ears. Vocals are silky smooth.
Listened for maybe a couple hours so far. It will be interesting to see how these change over time. So far I am hearing tracks like the first time compared to listening on some of my other headphones 560s, HD 650, SR225e. They sound good at lower volumes too which is a positive. Loud sounds incredible but those highs will hurt after....
For placement on my ears I push them a little bit forward as I do with my other Grados.
