The T1 bass is like a phantom; I can feel some solidity and notes but no steady lines. And the upper reaches of the treble are still absent....
Recently I compare HD800 and T1 in my system: Benchmark DAC1 > DA&T HA1*. And found some interesting things.   * A Taiwanese native powerful, high current class-A SS amp.    1.T1  has silght more weight and power than HD800, this is somehow confused me, because T1's diaphragm only 44mm,not as big as HD800.   2.HD800 not as neutral , or not as uncolored as i thought , it's has some silver-like tone color,and make Instruments juicy or liquid than real....
Keep your K701, and wait AKG announce their new flagship.

Again, If T1's highs sounds roll-off, that's mostly because amp's output stage not "fast", or "sensitive" enough.
Sorry for offtopic     This is stereophile's HD800 measure   http://stereophile.com/headphones/sennheiser_hd800_headphones/index4.html   Very different to headroom's    
T1's impedance graph seems is limited by headrooms data system. You may try to ask Tyll for original measure data?  
Take T1's graph for example   http://www.headphone.com/buildAGraph.php?graphType=0&graphID[]=2033   Just change 2033 to 2031,  and set graph type = 0-9     HD800's freq response url is   http://graphs.headphone.com/graphCompare.php?graphType=0&graphID[]=863   Set it to   http://graphs.headphone.com/graphCompare.php?graphType=4&graphID[]=861   You would got HD800's phase angle.      
In some radial conditions, T1's treble would sounds roll-off,bright and cold.   That's the Electrical phase angle relate i guess. A tasks to amp's output stage.
