A quick note to say I tried the bass+ mod, inserting a needle through the port, heating it with a lighter, then twisting it out to make a nice clean hole... a moderate increase in bass (I now no longer need any form of EQ), also widening of soundstage... not bad for a zero cost mod!
I just hooked these up to the Lisa III XP... wow, I can now start to hear what these things are truly capable of... very neutral across the whole spectrum, extremely fast and detailed with a beautiful euphonic mid range. Bass is slightly ill-defined but that's to be expected with IEMs, and particularly single driver designs.
Whilst not up to the Ultrasone Edition 9's, it's definitely 85%-90% there, and considering the SA only costs 15% of the UE9s it's a bargain... these little IEMs continue to surprise and excite me... it's now got me thinking about what a recable might bring to the performance... a silver cable could be very small and lightweight.
Also I've tried the Comply T-100 foamies, they're much more comfortable and sound just as good as the Shure yellow foamies I'd been using before.
