I dig its design as well, the Aune s6 also, that i find very fine looking and with volume control (something i miss on the Khadas)aune s7pro Headphone Amp PLZ
I really want to know if its performance matches the perfect look.

I don't have any leads on those as of now. How about posting on Gearstluz to see if any owners want them measured?I'd be very curious to see 2 channel DACs measured from the pro world, particularly these companies:
And then PS Audio Stellar Gain Cell DAC, and the Sennheiser HDVD 800.

Will do.I don't have any leads on those as of now. How about posting on Gearstluz to see if any owners want them measured?

We decided to stay out of that cycle and design, from the ground up, a discrete DAC whose unbeatable staying power results simply from being more than 10 years ahead of the performance curve. There's room enough for improvement: today’s best DAC chip claims no better than 22 bits’ worth of dynamic range and only 20 bits’ worth of linearity. High resolution music deserves better than that. MolaMola’s DAC is designed from the ground up using circuits and digital algorithms that were entirely developed in house.
The converter is a three board stack that fits in one of the option slots in the preamp. On the first board, all incoming digital audio is upsampled to 3.125MHz/32 bits and converted to noise shaped PWM. The two remaining boards are mono DACs, in which a discrete 32- stage FIR DAC and a single-stage 4th order filtering I/V converter convert the PWM into analogue with a breathtaking 140dB SNR. This is near the theoretical limit for 24-bit files and far beyond that of even quad-speed DSD. Uniquely, distortion remains below the noise floor even for full scale signals
Full-Scale Output Level: 20 dBu
Signal to Noise Ratio: 140 dB (standalone version), 130dB (preamp option board)
THD, IMD: not measurable (estimated -150 dB).
Bandwidth: Up to 80 kHz.
Integrated jitter: <1 ps from 10 Hz upwards, <300 fs from 1 kHz upwards.
Jitter rejection: >80 dB at 1 Hz after 20 seconds of lock.
That's a cut and paste from the datasheet for the chip. These finished amps usually don't come close to those specs.TDA7293 100wx2 amplifier with claimed Total harmonic distortion (Po = 5W, f = 1KHz) 0.005%;~$130
The measurements show a SINAD of 85 dB or so. Not bad but nothing great either (median for the amps tested is 80 dB).1200W amplifier for subwoofer (has measurements provided by seller on description) ~$350
This one looks interesting if the parts and specs are not fake. Love the old-school TO-3 Transistors. They are quite expensive but dissipate heat well.MJE15024 MJE15025 Class A amplifier ~$200
