Test report HiFiMan HM-801: Power Amp Board V2.0 (Test report)

Total reports 1 from HiFiMan HM-801


About this report

This is a report for professionals with a suite of test of headphone amplifier.

You can see a simple report for "dummies" with explanations of the main characteristics for HiFiMan HM-801 Power Amp Board V2.0

One product can have multiple reports in different modes and with different a suite of tests.

A suite of tests for a headphone amplifier can be applied to just a universal output without a formal presence of an amplifier, if in this mode you can connect headphones to this output. Based on the results of the tests, you can understand the real picture, is the output powerful enough or not, with the initial data on the circuitry as a "black box".

Comparison of basic characteristics

How much are the characteristics of HiFiMan HM-801 Power Amp Board V2.0 different from other models?
This can be compared for all measured amplifiers

In the general table, you can compare the characteristics: Sort and select by the manufacturers.


Подбор по характеристикам

You can use the automatic selection of the optimal headphone models for HiFiMan HM-801 Power Amp Board V2.0 from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.

During the selection of headphones, they are selected according to the characteristics and on a five-point scale are estimated the optimal bundles of headphones and HiFiMan HM-801 Power Amp Board V2.0. The selection takes into account the power characteristics of the amplifier, the sensitivity and resistance of the headphones, as well as the conditions in which the bundle will be used: at home, in the studio, on the street, in the subway, etc. The compatibility analysis is similar to car analysis based on its clearance - on which road the car will optimally go without evaluating the class of the car. The selection method by characteristics is developed in RAA.

Comparison of the power characteristics of the amplifiers and the determination of the required voltage level for the headphones from the amplifier

How does the power graph from differ from other models and what is the interaction with the headphones?
Compare the graphs on-line with an additional analytic of compatibility with headphones.

Graph of output voltage by power characteristics in different modes. Comparison on-line with other amplifiers. Estimating the sufficiency of the modes for the selected headphones by volume level.

Comparison of amplifiers by loudness (Volume Level)

How much Volume Level different from other models?
