I bought the Beyerdynamic T5p a month ago to use in the office. I love the Beyer sound, and would have gotten a T1 if it weren't semi-open, I know the T5p is "portable" but I need my 'phones to be closed. For real portable use I use my Shure SE530's with the Graham Slee Voyager. Now that I've got the T5p, I want to setup a desktop system for office use. In terms of my source, I use the iPad2 with the Camera Connector to output a digital signal, going into a Pico USB DAC (no amp).
Here comes my question. The GS Voyager is a good amp when paired with IEMs, but according to some people's opinion, the T5p should be driven by a real desktop amp to deliver its true potential. I know the T5p is supposed to be "portable" with only 32 ohms of impedance and "easy to drive". I find that if I use the Voyager with the Pico USB DAC combo, they are a little too bright. I guess I am looking for a good synergy with these 'phones paired with a desktop system. I don't need a DAC since I've got the Pico, but if a good amp+DAC combo matches well with the T5p, I can always sell the Pico.
Since this will be used in an office environment, I'd prefer SS over tubes, and size not too big to avoid pesty curiosity from co-workers. My music preference is pop, soft-rock, jazz and classical (in that order).
Anyone with the T5p to offer some advice and your experience with different amps? Are portable amps really not that powerful for a supposed 32ohm, "easy-to-drive" 'phone?
