The T5P's have a lowish impedance so mobile phones and DAP's shouldn't have any issues with powering them.aren't the T5P's primarily more for mobile devices? I am curious how T1.2 sounds on the Chord stack.
However the better the source the more they will shine. For my ears they have great synergy with the Mojo and Hugo 2.
Note that I had them connected to a Beyerdynamic A2 headphone amp using both the Mojo and Hugo2 just as a DAC. The T5P Gen 2's showed the A2 was veiling the music and not showing the Mojo and Hugo 2 their full potential. The same was when using a Violectric V280 balanced and single jack headphone output which in fact was more veiling than the A2.
I also tested the T1 Gen 2 for two weeks along with the HD800S's with the same rigs as the T5p Gen 2. The T5P out performed them so I returned the T1 back to Amazon and sold my HD800S's.
Today I got the ok that I can return the ex-demo Meze Empyrean's back to the hifi shop.
