Headphoneus Supremus
After doing some comparisons last night I've ordered my IEM listening preference:
ZhiYin QT5 > TK13 > Shockwave III > TK12
They're arranged by my priorities based on:
1) Soundstage
2) Timbre
3) Mids
4) Treble
Notable impressions:
QT5 has the best stage, hands down- it's enormous. Compared to the TK13 both its timbre and mids are great (slightly recessed due to the increased head space but not by much), though not nearly as remarkable to my ears as the TK13. Treble on both are excellent but at the end of the day I think the QT5 gets the win for overall appeal.
Shockwave III is also close to the TK13- however I find there is some resonance (which gives the timbre a metallic coloration). It isn't a huge issue- I only noticed through A/B'ing with the other three.
Whether you want to spend $250 or $100 the ZhiYin QT5 and TK13 are an incredible value for their respective price/SQ.
Thanx, you know your opinions are highly valued.
