I've no doubt Z5 is smooth n sib free, yo ;) cheers Just to make sure we're on the page. Ref plane - 10 khz resonance, the further from ref plane - the more 5-8 khz resonance. Not without exceptions, but that's the rule. Look at Z5 graph. They're smart at Sony's. Warm mids and very smooth...

Sibilant at 10 khz? OK, you took ref. plane measearuments? And do you realize you'll probably get quite a different picture given 6mm from ref. plane? Like, longer bandwidth, no 10 khz peak. And a listener will never ever be able to insert Z5 deep in his ear canal to the ref. plane without...

Quote: Crossover components do (inductors and capacitors). The effect may be very insignificant.

Quote: Yes it has, if it is TRS (it is not balanced), actually I don't like it it all (via TRS you get crippled buffer amp). To use TRRS balanced you need TRRS jack and cable, which open up immense soundstage, wider and deeper than with GAME. You may try RE-272 or RE-ZERO (with TRRS stock...

Quote: Buying PP6 I know nothing except it has unique CIEM active cross plus amp unit. No questions. But we also stick to DAC, which is what? Is it true DAC comparable with top-tier portable players or is it simply audio hub (DAC plus amp combo) like in my smatrphone? Why so secret?

So, what DAC chip is inside?

Quote: Well, that's something to start with. I'd look into more advanced and very affordable IFIHI 960. You really can't go wrong with either. :) While toying with the idea to order PP6 (not sure if the DAC is good), I am really tempted to try Miracle with upcoming 901 with TRRS...

Quote: Miracle is easy to drive (high sensitivity, low impedance), yet that doesn't mean they do not require an amp. First off, due to very low impedance (of even extremely low along the curve) you end up listening to piles of harmonic distortion via your IPod/Clip. That and similar...

Miracle vs 1964 V6 *lost*

Quote: OK, thanks. Haven't got an answer from them so far. Tried web site contact form, emailed them. I'll tell you more, they have no security certificate for web transactions... Suspicious enough.   As for marketing, I've seen much worse cases. )  That said G12 looks promising: 6...
