All I can say after approx 72 hours of burn in.... is that,, T1 indeed sounds special!!!! Just like the reviews that i've been reading here.
Pairing it with DX100 and tg334... This combo sound oh so sweet, absolute joy to these ears

Background noise is non-existence... pitch black.. so definitely improvement to the clarity and overall definition and i can also hear that soundstage is slightly bigger.
For me the most improvement is the smoothness and how things sorta flow together effortlessly
Guitar plucking got that extra "twangg" sound and on some track i could hear more bass reverberation...
Will post more impression when I got more burn in time with this lovely amp.
