@John Atkinson you should do better. How can you look us in the eye (metaphorically speaking) and say "inevitable compromises have been managed well" when you measured 68.4dB SNR in the audio band?FYI, owner said he heard it at a dealer and it had hum in one channel! So my results must be accurate. See how JA concludes his measurements:
"With separates, it is possible for the designers to maximize resolution and minimize noise. With a single-box solution like the Roksan Attessa, it is difficult to do these things, with the current-heavy power supply in such close proximity to the low-level analog and digital decoding stages. However, the Attessa's measured performance, especially that of the low-noise, low-distortion phono input, indicates that the inevitable compromises have been managed well."
This, while measuring SNR of just 66 dB at 1 watt: "The unweighted, wideband signal/noise ratio (ref. 1W into 8 ohms), taken with the inputs shorted to ground and the volume control set to its maximum, was 66.5dB (average of the two channels), ...."
No wonder these companies sit still and don't think they have to do better. 66 dB is just 11 bits of dynamic range!
Yes, you are earning a living but you also have a responsibility to the consumer. We should trust you. You should tell us when a manufacturer is not doing well. Not the opposite!
