You'll hear differing opinions about every headphone known to man. Of the criticisms I've heard of the T1s, I don't recall hearing "boring" until you just mentioned it. I bought my pair after purchasing the 880/600ohm and just feeling as if they were missing something. That's not a knock on those headphones cause they have a very large following of happy users. But for me I wanted something a bit more, particularly in the mids, which I felt were a little recessed on the 880s. The T1s have hit the mark for me in that regard. I don't really find that they have one particular area where they are the "best" at something, which is okay because they do pretty much everything well. They are extremely comfortable over extended listening sessions, they have a nice, clean bottom end, and I feel both the imaging and sound stage are solid in accuracy and scope, respectively. On top of all that, they just look awesome
One thing you'll hear is that the really need a proper partner in terms of the amplification. There are reports that these phones will scale up with higher end amps, just as they are some pairings that yield less than satisfying results. In my situation I relied on my prior knowledge of Jan Meier (of Meier Audio in Germany) and his love for the T1s, so I went with one of his mid-range amps, the Corda Jazz. It's a great pairing that didn't break the bank and I've been very happy with it. Others have found their bliss with a Woo Audio amp, some have really liked the synergy with Burson, others have gone in different directions.
So I'd try and arrange an audition if possible, and if they are to your liking - as they have been for many (many, many, many) of us, just choose the amp carefully and you'll be rewarded with many hours of sonic goodness.
