Linear power supply
#21
Hi....Several USB powered D/A converters you have tested have benefited from hub-fed power as opposed to port power have they not? An SMPS is arguably less likely to have stronger mains harmonic spurs depending on how well it was designed, but it will gain noise at the other end of the spectrum.
And in terms of reliability, there is no comparison whatsoever when it comes to low power, low cost SMPSs (like the majority of ones used for small desktop devices you review en-masse here) vs an equivalent linear supply.
