I setup my JRIVER with a random 100 song list out of the thousands of tunes I have ripped....and its very, very revealing when the recording is great and when its not...
I have stopped looking or trying to tune my amp and dac to make material sound "good" to me....
I have accepeted the O2 amp as being as transparent as it needs to be as well as the ODAC..
So I believe I am hearing what the T90s sound like or what they can reproduce to my ears..
So its money spent on material and music....when the material is done right, something i like and am in the mood its magical.
The T90s are indeed a "Classic".
Well said Alex. ODAC/O2 for transparent, ODAC/Crack for euphonic. T90 for cans. Own all of those and can vouch for the quality of said pairings. Could live with that if I was budget constrained and not worry about the last 5%. Very fine sound at this point that allows one to hear and get lost in the music. Takes a lot of effort, time and money to get the last 3~5%. Personally I will probably stop short of the last 2%.
