Topping D90 Vs Bifrost 2 Buying Guide
Sound Quality Considerations
When comparing the Topping D90 and the Bifrost 2, sound quality is paramount. The D90, with its AKM DAC chip, is often praised for its neutral and transparent sound signature. It aims for accuracy, presenting audio as the recording intended with minimal coloration. This makes it an excellent choice for critical listening and for users who want to hear every detail in their music.
The Bifrost 2, on the other hand, utilizes Schiit’s proprietary Unison USB technology and its own unique digital filter. This often results in a slightly warmer, more organic, and musical presentation. Some listeners find it more forgiving and enjoyable for longer listening sessions, offering a more “analog-like” feel. Your preference for clinical accuracy versus a more engaging, slightly warmer sound will heavily influence this decision. (See Also: Demeyere 5 Plus Vs Atlantis )

Do both DACs have headphone outputs?
No, neither the Topping D90 nor the Bifrost 2 typically include integrated headphone amplifiers or outputs. They are purely Digital-to-Analog Converters (DACs). You will need a separate headphone amplifier to drive headphones with either of these units. This allows for greater flexibility in pairing amplifiers with your chosen DAC.
How does the USB implementation differ?
The Bifrost 2 features Schiit’s proprietary Unison USB technology, which is designed to isolate the USB data stream from noisy computer internals. The Topping D90 uses standard USB implementations, which are still very good but may not offer the same level of noise isolation as Schiit’s dedicated solution. This difference can subtly impact the perceived purity of the digital signal.
Which DAC is better for gaming or movie soundtracks?
For gaming and movie soundtracks, both DACs can perform admirably, but the Bifrost 2 might offer a slight edge due to its more engaging and slightly warmer sound. This can enhance the impact of explosions, atmospheric sounds, and musical scores. However, the D90’s accuracy will also ensure you don’t miss any subtle in-game cues or dialogue.
Final Verdict
Choosing between the Topping D90 and the Bifrost 2 comes down to your sonic priorities. The D90 shines with its exceptional neutrality and detail retrieval, making it ideal for critical listening and those who crave absolute accuracy. The Bifrost 2, conversely, offers a warmer, more organic, and musical presentation that excels in long listening sessions and provides a more enveloping experience. Both are outstanding DACs in their class, but the Bifrost 2’s unique character and Schiit’s robust build often give it a slight edge for overall enjoyment and musicality.
