After a couple of hours with the RS1i, I have to say that I'm impressed. After nearly 30 days of really wanting to like the PS500 listening to it every day while my HD800 sat on the back burner, they just didn't work for me. Everything that I found lacking, the RS1i corrects. Flatter and a little more extended bass and the same with the highs while bringing some semblance of a soundstage back. The $100 or so price difference is an absolute no brainer give the difference in SQ, the metal gimbals and the extension cord and adaptor thrown in.
The Naim DAC-V1 is simply brilliant with the HD800 and is proving to be the same with the RS1i. I'm glad I gave Grado another shot after all these years. Count me in as a fan!
Congrats on your RS1i.....glad you like it so much....welcome aboard the RS1 lovers club
I'm lovin HD800 and 325is combo. Surprisingly, they share a lot of similarities in sound. Both have articulate, slightly etched highs, transparent mids, and textured bottom. end. On occasion I will use the built-in bass boost on the Fiio E12 that warms and gives body in the 100hz range. I have considered the RS1i mainly for these sound expectations and I imagine they are significantly lighter in weight. And... the wood factor - they're gorgie. also, I can say about the same as the sr325is silver. Can't I just have both?! I do tend to light phones aren't shy about getting putting some emphasis on the HF and some folks describe the RS1i high frequencies more melllow. I hope not too mellow.
Nah....the highs are not too mellow.....if you feel that they are you can always use a SS amp....that makes them more aggressive....or just EQ them a little.
With my MAD, I describe the highs as very detailed, with all of the rough edges knocked off...so they do not sound at all overly bright.....if that makes any sense to you.
