The Grado GH2 has arrived and I tested it with great expectations.
My SR325e and the GH2 are the test candidates. First of all, I notice the complete lightness of the GH2. The 325e is a bit heavier. I hardly feel the GH2 even after a long wearing period. Very pleasant.
Now I took my hi-res-player FiiO 2 II with different test songs from different music styles (jazz, classical, blues, pop, rock, ...) in different formats (FLAC, WAV, MP3, ...) and taken alternately both headphones. At the beginning, I had problems with the sound of real differences between the two. But then there were some passages from certain songs where I heard a finer vote with the GH2. Especially with jazz / blues, where guitars were in use, I heard the plucking of the instruments already. I did not hear that in the 325e. By and large, I can say, yes, the GH2 is a bit finer in tuning, hearing more detail, not banging the basses as hard as the 325e. However, if you see the price difference, I think it is too big. So much worse is the 325e not. You have to listen carefully!
You need to listen attentively to detect differences. I think if you do not compare them quickly, you will not notice a difference. If you only have the 325e you will be happy with him. If you only have the GH2 you will be happy with him. Only you know that the GH2 is a little bit better…
...but I missed the “WOW-effect” a little bit.
Now I'm still waiting for the PS1000, which should also arrive this week.
