What is the difference between TubeMagic D1 and TubeMagic D2
D2 is designed as a dedicated DAC. That means it has no analog inputs and headphone amplifier output like the D1 has. D2 is for people already have a stereo setup and using the D2 as just a digital to analog converter. D1 on the other hand has much more features and can be used in anywhere.
Is there a volume control for the TubeMagic D2?
There is no volume control on the D2. The reason is adding any kind of volume control (no matter it is digital or analog) will downgrade the audio quality in some way. Since D2 is a dedicated DAC, we think the volume control job belongs to the Amplifier or Active Speakers.
