I listen to s lot of music and hardly watch Tv. It's my main source of entertainment but would not describe myself in any way an audiophile, listening to most of my stuff through only average entry level hard ware. On a complete whim I bought myself a Teac HA P50 in an effort to boost my listening pleasure. What I didn't realise was that my cans aren't really up to the job. I have some Shure SE300 series in ear from about 5 years ago that have hardly any bass and a pair of AKG450 that sound the same to me with or without the amp. I want to get something below £300 if I can that will make the most of the Teac. I also need to go a way to improve my source music, but that's another matter. If anybody could offer any starting points for me to research in terms of compatibility, it would be much appreciated. In ear would be preferred for portability. I'm using an iPhone 6s as the music source when moving.
