Thanks shigzeo. Whatever I end up getting it will be used for a combination of work and play with different sources. Even if the majority of material is good quality, enough will be lower quality that I need to make this a serious consideration in my choice of IEM. I'm not so keen on the idea of having multiple IEMs for different things, but it is possible that I could choose something much cheaper and end up with different ones for home/travel/work.
I do have fit/comfort issues, so I was considering the Westone 2 and Earsonics SM3 in combination with ACS custom sleeves as a lower cost alternative. However those combinations are expensive enough that the T2 is not vastly more, and while the T1 is a further step up it is within the realm of attainable (and I'm in the UK so ACS is much more cost effective than any other customs)
