Have had the T5p for some time and always loved the sound and clarity. Ordered the T1 to go with my new WA7 (if it ever gets here) and so in the meantime I been comparing the T1 and T5p on the same amp, a HeadRoom Ultra Desktop Amp, a very clean and strong solid state amp. T1 using the medium gain setting and the T5p using low gain.
The T1 only has 25 hours white noise burn in on it but WOW, it just kicks the a** out of even the T5p which until now I thought was perfect. I still love the T5p sound and each has it's own space to live happily in but the T1 really shines bright in a more stationary setup with a more powerful amp. I really can't wait now to finish the burn-in and then hear the two on the WA7
