Are the Sennheiser HD600s really loud enough just using the built in headphone amp? They are at 300 ohms, and people in this thread swear by them. But then I see people on 250 ohm DT 770s saying they don’t really get all the juice they want out of the Kemper and I think to myself “250 is 50 less than 300”. I don’t want anything crazy loud. If anything I’m pretty sensitive when it comes to headphone volume. But I don’t want to find myself lacking a db or two when I max out the Kemper, and I’m in the market for some reference headphones.
Remember it is not all about Ohms, the sensitivity and SPL tell as much about how loud a Can can be (lol), one example are the K701, only 60 ohm, but harder to drive than many 200 Ohm Headphones because of their low sensitivity.
