To me the T1 (in comparison) was more laid back (athough not a laid back can) and "trebley" while th T90 were so impressive in mids.
I just cannot picture anyone buying the T1 for just a good detailed sound.
It should be freaking amazing at that price.
Something like the T90 was amazing on vocals clarity that made me jump paying so much I would NEVER buy at this price range without listening first.
My 2 cents..
but you're wrong, T1's are freaking amazing.
