Integrated DAC/Amp vs Separates — Which Should You Choose?
A comparison of the pros and cons of integrated DAC/amp units versus separate components, with guidance on how to decide.
The Difference Between Integrated and Separates
An integrated unit houses both DAC and amplifier functions in a single chassis. A separates setup uses independent, dedicated devices for the DAC and the amp.
Advantages of Integrated Units
Space Efficiency
Everything in one box means a smaller desk footprint. Cabling is simpler too, making setup and cable management easier.
Cost Efficiency
At the same budget, an integrated unit often achieves a higher overall sound quality level. This is because power supply and chassis costs are shared across a single device. For example, the Topping DX5 (¥55,000) offers more polished performance than buying a DAC and amp separately at the same total price.
Simplicity
Plug in the power, connect a USB cable, and you’re ready to go. Impedance matching and gain setting issues are less likely to arise.
Advantages of Separates
Individual Upgrades
You can upgrade just the DAC or just the amp incrementally. This lets you spread your budget over time while gradually improving overall system quality.
Optimal Pairing
You can independently select an amp with the right driving power for your headphones and a DAC with your preferred sound signature. For example, pairing a Topping D90 (DAC) with a Lake People G111 (amp) lets you combine the strengths of different manufacturers.
Noise Isolation
Physically separating the DAC and amp sections reduces electromagnetic interference between them. This is particularly beneficial when using high-gain amplifiers.
Recommendations by Budget
Under ¥50,000
Integrated recommended. Going separates at this budget risks making both components mediocre. The iFi Zen DAC V2 and Topping DX3 Pro+ are solid candidates.
¥50,000–100,000
Either works. For integrated, consider the Topping DX5 or iFi NEO iDSD. For separates, something like a Topping D50s + Schiit Magnius combination.
Over ¥100,000
Separates have the edge. At this budget, you can allocate meaningful funds to both the DAC and amp individually. The Topping D90 + A90 stack is a prime example.
Common Questions
Is the Amp Section in Integrated Units Weak?
Not necessarily. The Topping DX5 and RME ADI-2 DAC FS have perfectly capable amp sections. However, for demanding tasks like fully driving planar magnetic headphones, a dedicated amp will have more headroom.
Do Separates Always Sound Better?
At the same budget, an integrated unit can sometimes win. Separates truly shine when you have the budget to invest properly in each component.
Conclusion
If you’re building your first desktop setup, go integrated. If you already have a system and want to upgrade incrementally, separates are the logical choice. Weigh your budget, desk space, and future upgrade plans to make the right call.
