I use a Peachtree Audio DAC*IT and a Schiit Asgard. The Asgard is 1ohm output so it's out of the question if i decide to go T-1, 800. That's why i am considering an amp that has different impedance options such as the vio or the burson. I listen to everything and have high bit rate recordings. Thanks for the input about how the amp won't change the headphone.
You say that i can get higher quality recordings and i won't be subjected to the the harshness does that mean that the T-1 is harsh and fatiguing if i don't play better recorded music?
I suppose i wouldn't mind getting a 650 for pop and genres like that as those genres are only sometimes fun to me and vocal, acoustic, live and orchestra are the music that melts me enough to engage in this high dollar hobby.
Sometimes the quality of the recording does not scale up with their bit rate. You have have very nice CD recordings that has no sibilance at all, and you could have bad high res recordings that sounds like crap. But, in general, higher resolution recordings are good recordings in the first place. I think harsh fatiguing sounds varies from recordings to recordings, so I cannot say for sure that T1 will sound harsh for all your collections.
As for me, I never found acoustic, live and orchestra sound harsh at all due to the nature of how they recording things. Vocal is the one that sometimes troubles me, with most Jazz that recorded in a room, I found no problem with treble. But with some other tracks that recorded in the studio, sometimes "S" and "Ch" sound will kick in too strong and make your ear uncomfortable.
As I have stated, with high quality recordings, the treble should not be a issues to you. (please do not try Eminem on T1, last time I did, I stop listens to music for a week~~~ )
