Just noticed this - I would suggest contacting
@amirm directly by clicking 'Start a conversation' on
his profile page here. There are a lot of people on this forum who would be very interested in seeing objective independent measurements of the Qudelix 5K, so I hope you can arrange to send it in and be measured
It seems like a unique device, offering dual ES9218P SABRE DACs (which the much lauded LG G7 uses), high-powered SE and balanced output, optional LDAC Bluetooth, and
now with 10-band parametric EQ and an app for system-wide EQing from any source e.g. a smartphone with the recent firmware update. Amir also seemed impressed with the designer's knowledge which is a good sign, when he reviewed his previous creation, the Radsone Earstudio ES100, before he moved on to found his own company in Qudelix and design the 5K.
