Thank you for the kind words. I'm glad you were able to correct the balance issue as well.
It is true that, in an inexpensive design process, jitter usually is not addressed properly, if at all. The performance of these devices are usually very dependent on digital cables (length and quality), as well as source transmission.
I should say that this is not limited to inexpensive devices. We recently purchased another manufacturer's D-to-A device that has recently experienced a surge in popularity. (I won't mention the name of the manufacturer nor the device, as we refrain from publicly critiquing competitors. I will note that the device cost significantly more then the DAC1). We tested the device on the Audio Precision (AP) testing station, and we were shocked to find that this device had absolutely NO jitter attenuation!! In other words, if the AP induced the slightest amount of jitter on the digital signal, it rendered itself directly as distortion within the device. Here is a picture of the result of 0.25 UI of jitter at 44.1 kHz.
The spike in the middle represents the audio - the only signal that was meant to be heard. The spikes all around it represent jitter artifacts at frequencies ranging from 100 Hz to 9 kHz, in steps of 300 Hz (ie, 100, 400, 700, etc.). The magnitude of the jitter is a very small 0.25 UI.
