This is contrary to some opinions I have seen that because USB is a "general" computer interface, it is somehow "bad" for audio. coaxial cable with the Squeezebox Touch to the TEAC DAC. This is I think nicely demonstrated above comparing USB output vs. Remember that whereas asynchronous USB can be free from jitter, S/PDIF interfaces (TosLink, coaxial) are generally not.
I would certainly like to see some objective evidence from those making the opposing claims.ģ.

I am basing my opinion on the measurements above plus my own experiences over the years. I realize that this statement is in contradiction to some articles claiming otherwise - such as this one. Subjectively and objectively, I have no reason to believe that a digital source changes the sound through a good asynchronous USB DAC. Digital output through USB to an asynchronous DAC (the TEAC UD-501) is free from jitter and measures just as well as other devices.

Compared to the original Squeezebox Touch, the HiFiBerry DAC+ Pro has lower noise floor, less stereo crosstalk, but a bit higher intermodulation distortion.Ģ. No evidence that increasing screen brightness adds any extra noise or causes sonic deterioration. No evidence that the addition of the touchscreen affected the sound quality.
The analogue output from the HiFiBerry DAC+ Pro is as measured previously. Remember too that I'm just using the inexpensive US$8 switching power supply, no fancy USB reclocker, no expensive linear power supply, and simply generic cables.

The "Pi Touch" device sounds great already and the objective results simply confirm what I've been hearing from this device with a touchscreen LCD grafted on and using UI software ( Jivelite). Note that the 37kHz noise is from the Focusrite Forte ADC and not from the Pi 3 device. This also reduces or removes 60Hz AC hum in the measurements.Īs you can see, there's no evidence of noise whether the screen is off at 0% brightness, dim 25% or bright 100%. Remember that the Focusrite Forte can run completely USB-powered off the laptop which makes it convenient that I don't need to have the computer or ADC plugged into the wall. Very straight forward test of the analogue outputs from these devices. On the computer screen is the FFT of the 24-bit jitter test probably from RCA output of the SB Touch based on how the cables are arranged. Obviously to get the touchscreen working on the "Pi Touch", I activated the Jivelite interface in piCorePlayer.
The TEAC UD-501 I believes uses the Tenor (TE8802L?) USB chipset so you need to use the Triode Kernel #12 to get it working - check out this "how-to" page to get it working.īelow, you see the simplicity of this testing setup with both the "Pi Touch" and an actual Squeezebox Touch connected over WiFi to my Logitech Media Server machine in the basement, playing various test tracks. The Squeezebox Touch was updated with the EDO (Enhanced Digital Output) plugin that allows output to 192kHz with the custom kernel. These measurements are made with default piCorePlayer configuration settings, not the CRAAP tweak :-).
I made sure the screen stayed on with the "Currently Playing" album cover displayed during testing. The "Pi Touch" device had the screen brightness up at level "50" (unless otherwise indicated) using the latest version of piCorePlayer available currently (3.20 Normal Version the "Audio optimized" version seems to not recognize the touchscreen properly for changing brightness in Jivelite).
