Yesterday I met a dear friend for the usual gear-swap sessions. This week’s new entrants are QDC King, a Musciteck colab with QDC and the Vietnamese TXN Diamond.
QDC King is a 15 drivers tribrid with a single DD (10mm) for ultra-lows, 4BA lows, 2BA mids, 4BA highs, and 4EST for ultra-highs (source).
The sound is characterised by an elevated, yet nimble bass, with good elasticity, very clear mids and energetic treble. Sort of a V shaped profile. A nice touch is the vent that also serves as a L/R identifier.



TXN Diamond is a single DD, with a diamond-coated dome driver (source).



The sound reminds me of Maven 2, with a quick bass, that can sound ample but is non-intrusive, gritty mids, but with significantly more energy in the upper mids than Maven 2. For the time being is paired with the Ulan 8w cable.
Thanks to the generosity of my friend, I had enough time to prepare a full opinion on the TXN Diamond. You can read it here.
