Shure SRH 1440 - Compatibility with amplifier sources

After testing in the benchmark mode in the Reference Audio Analyzer software, the data is added to the online database of the RAA website.

You can view the test results on the comparison pages and summary reports for beginners and professionals. You can go to the desired report or comparison/selection service through the menu on this page. Additionally, you can go to the comparison pages from any graph in this report and add other tested products for direct comparison.

This is the Shure SRH 1440 compatibility report with amplifier sources.

С 2024 года измерения полноразмерных наушников в RAA проводятся не только на инструментальных стендах, но и вживую с помощью разработанной системы в RAA - Live Measurement System. Это позволяет увидеть реальное поведение наушников и их вариативность звучания относительно стандартных стендов. Результаты таких измерений в отчетах обозначаются как со стендов Human. В этом отчете - это:

Т.к. АЧХ зависит от посадки наушников и их прогрева/износа, то в RAA была разработан универсальный комплект Live Measurement System для контроля своих наушников на собственной голове. Типовые комплекты доступны для приобретения.

Brief information

The test shows a change in the frequency response of headphones when connected to amplifiers whose output impedance is constant in the operating frequency range. The change in frequency response depends on the impedances of the headphones and the amplifier.

Variants of amplifiers with resistances are selected for analysis: 10, 20, 50, 100 and 300 ohms. In the comparison service, you can select any measured amplifiers or use the function tools to set your amplifier by parameters.

The impedance of the amplifier can be of different sizes and, when matched with the impedance of the headphones, the frequency response changes to varying degrees. The lower the output impedance of the amplifier and the higher the impedance of the headphones, the smaller the changes. If the impedance of the amplifier and headphones is flat lines, then there are no changes in the frequency response.

The change in frequency response is gustatory in nature, as an additional equalization or timbre adjustment, leveling or coloring the final sound of the headphones. If desired, the effect of the amplifier can be partially corrected through equalization through the export functions to RAA on the comparison page.

On the frequency response comparison page, there is an export option and additional tools for adjusting the frequency response

Brief information

The test shows the deviation of the frequency response of the headphones when connected to amplifiers, the output impedance of which is close to zero in the middle and high frequencies, but increases in the low frequencies. The change in frequency response depends on the impedances of the headphones and the amplifier.

An average version of this type of amplifier was selected for analysis. In the comparison service, you can select any measured amplifiers and look at the individual result.

The higher the headphone resistance, the smaller the changes. The change in frequency response is gustatory in nature, as an additional equalization or timbre adjustment, leveling or coloring the final sound of the headphones.

More detailed

Measurements of Shure SRH 1440 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Shure SRH 1440 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a source amplifier and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.
