Hey Spyro,
It's been fascinating reading/'watching' your IEM & customs journey in the last year or so. It's refreshing to see you're honest about some of your previously held views.
Now, I've been wondering for some time why you haven't given some of the latest DD IEMs a chance. I'm not just talking about my all-time favourite, the EX1000, but others (cheaper even) such as the MDR-7550, EX600, FX700, FX500 & GR07. I think you might be in for a surprise if you tried one/some of these, and being based in the US (at least with the Sonys) you always have a chance to try them out and if not entirely convinced, get a full refund.
On a side note, I've no idea how old you are - and I know this is none of my business - but I think you should seriously think about the volume levels you're used to listening to music - you know, hearing loss is a very real thing and something to seriously think about. I'm passionate about music and at times I, too, crank the volume up, but quite a while ago I learned to 'discipline' myself and listen to music at lower volumes to preserve my hearing; eventually I got used to it and now I get plenty of 'eargasms' at such 'lower' volumes, though I have to admit that in the last 3 months that task/discipline has proved more difficult with the EX1000s - seriously! -, but for the most part I manage to not go over 40%- 50% with my 4G Touch, which is a brilliant sounding DAP, BTW. Volume levels isn't that much different from the amount of food we eat. Apologies in advance for the unsolicited advice.
