I have a question for the T1 users, and possibly HD800 users as well. I plan to sell all my headphones except the DT880/600, being in need of something to be complementary to it. I try to evaluate all your points, reviews etc while trying to make a decision between HD800 and T1, but I perhaps need some direct approvement/disapprovements to my ideas.
Now, what I, from all the reviews, so far think is that T1 is a better version of DT880/600. Though many of you think that it is somehow different than any other previous beyer model, the graph from the headphone.com, to which I give importance, demonstrates that I should expect a very similar character to the DT880/600 - it is probably much more refined, more organic from top to bottom and more detailed. I do not doubt it is a better version of DT880 actually, but I doubt how it can complement DT880s. I listen to classical, folk (celtic especially), rock, jazz and heavy metal (mostly sympho/power), and DT880/600 covers all those greatly in its own class. I've auditioned some HD800s, on the other hand, and it can also fit into my preferences with a much brighter sound compared to the previous Sennheisers, which I do not like, and a much better soundstage that I guess the beyer house cannot provide including the T1s and I might enjoy that. I can call myself a half beyer fanboy btw - have owned a DT880/250 '05, DT880 2003 and DT880/600 - but I have to make an accurate decision here.
If I buy T1s, It seems like I'll throw away my DT880/600 after sometime; but if I buy HD800s, I can use it for acoustic - folk - classical etc while still enjoying DT880s for heavy metal - or just call it relatively faster music - I guess. So the question is, you can only afford one of those monsters (T1 or HD800), and you already have a DT880/600 that you love. Which one would you prefer for a all-rounder setup?
