Common Mistakes to Avoid
Buying too much power: A very powerful amp is not automatically the best choice.
Ignoring headphone compatibility: Check the headphone type and connection before buying.
Paying for unused features: Extra functions can increase the price without improving your actual setup.
Forgetting desk space: Some desktop amps are much larger than others.
Ignoring your DAC: If you already own a DAC, buying another may not be necessary.
Choosing only by specifications: Numbers are useful, but the amp should also match your headphones and listening needs.

Frequently Asked Questions
Do I need a headphone amplifier?
No you don’t always need a headphone amplifier. Some headphones can run well directly from a phone, computer, or other source. A specific amp becomes more useful when your headphones need more power.
Is a DAC the same as a headphone amplifier?
No. A DAC converts digital audio into an analog signal, while a headphone amplifier provides the power needed to drive headphones. Some products combine both functions.
Should I buy a DAC/amp or a separate DAC and amp?
A DAC/amp is usually simpler and takes less space. Separate units make more sense if you want to upgrade different parts of your system independently.
Are balanced headphone outputs necessary?
No. Balanced outputs are not required for every setup. They are useful when your headphones and cables support them and the amplifier provides a suitable balanced connection.
Which one is best for an R2R setup?
The FiiO K11 R2R is the obvious choice among these three if R2R DAC technology is your main interest.
Which one is best for a high-end desktop system?
The FiiO K15 is the strongest choice if you want a high-end desktop DAC/amp with more power, connectivity, and features.
