Actually, I'm going for the "hybrid" option. Yesterday, I beat myself and my forearms up pretty bad while replacing a steering shaft on my car. Then, after that was done, I replaced my tranny filter, and added in new fluid. Muscles that I never thought I had were killing me. I'll head home in about an hour, so I'll just miss 1/2 day of work. I'll set up the gear, then lay on the heating pad to alleviate some of the pain.
I think I'll use the Aune T1 just for the tube DAC feature. I will pair it with my Little Dot I+ amp. However, I will try the Aune T1 on its own, too, to see what kind of impressions I can gather on how it performs with the Grado headphones. The Aune T1 is capable of putting out nearly 1 watt of power into 32 OHms, so there is more juice that the Grados desire. But, a watt isn't usefuld if the sound is only so-so. Time will tell.
