@Chris674 @citral23 Thanks a lot for your thoughts on the Knight
I'll think about it… actually I've just completed the first prototype of my custom DIY build based on Qian69 shell.. and it sounds incredible for my ears, basically much better tonally than anything I've had so far. Deep bass, touch of warmth, smooth natural mids and highs, plus details on the same level as RY4S UE. No sibilance or harshness, everything is where it should be, according to my current taste. With the fit and comfort of Q69 shell of course plus a 4usd driver, so it sort of knocked out the Knight for me.
Might as well buy better components and upgrade it further. Only problem so far is that it's incredibly easy to drive, can't go further than 1-2 volume steps on my dac, might need higher impedance driver
What would you call as a reference/well balanced sound in the sub 25usd scene? At this point I would rather need a good benchmark/reference for my diy builds, to evaluate the tuning and to provide with a point of comparison. BK2? Is there anything cheaper with very well balanced sound and good bass extension? Or a biti more expensive that worth saving up to?
