For the soundstage, I feel the new one is really between the ears, when the old one, sounds seems to come from everywhere.
Yes, agree, the sound of the original is thicker. But have you ever been to live concerts? When amplified music sounds so good, it is because, it is warm and TRANSPARENT, at the same time, meaning you do hear everything in detail, but sound is not flat, harsh or not involving. Instruments have a nice timbre , but voices are clear.
Sure everybody his taste, but the original, made me feel being at such a live concert, the joy of people playing, and not sterile digital sound. I also not say, that everything sounds bad on the second generation, but when I do my daily walk, I am thrilled when playing the first generation, and could go on for ever, when the new one, I am sometimes happy the walk is over.
I think also, that someone who loves his original one, must be warned, the new player is not an improved player for him, but another way to listen to music, and maybe not give the same pleasure. And as always, marriage is an imporant issuem as the second generation, will work better on colored cans, and less on neutral ones.
