Final Audio Design Piano Forte IX (report for a newbie)

General results Final Audio Design Piano Forte IX

  • Sensitivity by voltage: 127.98 dB/V SPL
  • Sensitivity by power: 110.66 dB/mW SPL
  • Impedance: 18.52 Ohm
  • The type of acoustic design Closed
  • Headphone: Low-impedance
  • Type of headphones: In-Ear or Tablet


This is a simplified report for non-professional users ("dummies"), poorly versed in the headphones characteristics and specialized graphs.

Information in this report presents in most simple and clear as possible. Interpretation of the data is simplified as much as possible and accordingly devoid of subtleties and nuances. This is sufficient for an overall assessment, but for a more complete and accurate presentation, the professional report should be studied.

By possible, the characteristics are accompanied by explanations to do reader possibility gradually master a more complex professional report.


For example when choosing a video card, many people do not understand the set of tables with the final data of the test packages. How to understand the relative difference in these figures? In most cases, the unprepared reader is satisfied with only the textual evaluation of the author, without delving into the figures. When the choice of a product is done thoroughly, then the reader gradually deepens into complex tables, mastering information from simple to complex. We made two separate reports: "simple" and "complex". A simple report with explanatory comments will allow you to self-study to gradually understand and professional report.

The table shows the most common variations of sound sources and the scope of use of AMPs and headphones bundles.

The compatibility rating is similar to car analysis based on its ground clearance - on which road the car will move optimal without evaluating the class of the car.

Detailed description formula of the table of headphones


If in your situation, the Final Audio Design Piano Forte IX headphones in the table do not have a high rating, you can choose more suitable headphone models in a special on-line selection for the selected parameters. If fully suited, then similarly you can see what other models may suit you.


For different purposes it is best to select individual headphones, and not to look for some universal headphones for all occasions. Unfortunately, some properties of headphones mutually exclude the use of headphones in different situations. True connoisseurs of quality sound use several pairs of headphones. Headphones are compact and do not take up much space, unlike speakers.

Sensitivity

The average value of sensitivity by voltage for In-Ear and Tablet headphones by measured 410 models is 128.3 dB/V SPL.

The Final Audio Design Piano Forte IX sensitivity is 128.0 dB/V SPL.

These headphones are 0.3 dB quieter than most In-Ear and Tablet headphones.This difference is insignificant and not exceeding a threefold deviation from the mean. So, most devices designed to work with In-Ear and Tablet headphones should fit quite well with the Final Audio Design Piano Forte IX. A sufficient volume should be provided during playback and background noise from the source should not be noticeable.

In general, to listen to music with a level of dB SPL in a quiet environment, the amplifier will require a voltage of -18.0 dBV.

It is desirable that the amplifier provides a margin of 12 dB in cases of rare noisy environments or for too quiet recordings. Thus, the amplifier should provide a maximum voltage level not lower than -6.0 dBV.

Excessive volume margin is undesirable, since for analog regulator, the adjustment range is about 40 dB and below that the channels imbalance begins. For a discrete regulator the pitch may be too large. For digital controllers are possible options for adjusting the sound level before a DAC or in a DAC. As a result of that will be decrease the signal-to-noise ratio and accordingly it is probable the appearance of audible noise.

The average sensitivity to power for In-Ear and Tablet headphones is 111.8 dB/mW SPL (average by measured 410 headphone models). The Audeze LCD-2C sensitivity is 110.7 dB / mW SPL. Final Audio Design Piano Forte IX have lower sensitivity than other headphones of this type. This means that their power consumption is greater and being connected to mobile devices, the operation time of this bundle will be short than of many others.

Measurements of Final Audio Design Piano Forte IX were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Final Audio Design Piano Forte IX 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.
