Hmm.. looks like the SB Zxr should be able to power the T90's. If you are ok to use EQ to tone down the treble (in case you find them bright), go for it, you will find them much better than DT 880.
you will have to lower the 8k & 16K bands for them to sound less bright if the treble bothers you (rest of the bands will be flat i.e 0 db).
