Below is a list of links to comparison charts for the major types of hardware reviewed, measured and tested on ASR. They will be updated as more reviews are done.

As always, please message me if you catch errors.

ADC/DAC Charts
Power Amp Charts
Headphone Amp Charts
Phono Preamp Charts
Portable DAC/Headphone Amp Charts
A few notes:
  • Power measurements are made by driving both R&L channels and recording the result before the onset of clipping.
  • SINAD and SNR measurements are made by averaging the R&L channels.
  • Chart colours are organized by quartiles, with blue being best and red worst. The only exception are the headphone amplifier output impedance charts, where colours are organized according to the measured values. The legends include the defined ranges.
  • At one point I wanted to create compiled max power charts to show the variation in output for each kind of load, but these charts quickly lose meaning once there are too many entries and so won't be posted until we come up with a cleaner way to present this data.
Finally, please don’t take the measured values too seriously. Small differences are not material and results vary slightly from test to test. A reasonable effort is made to represent the best case scenario for each piece of hardware.
