Burson Audio Conductor 3X Reference

Hi Level Single-ended Out
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 Burson Audio Conductor 3X Reference Hi Level Single-ended Out

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".

More detailed

Measurements of Burson Audio Conductor 3X Reference Hi Level Single-ended Out were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Burson Audio Conductor 3X Reference Hi Level Single-ended Out 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 headphones 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.

Comment to the Burson Audio Conductor 3X Reference AP FAST professional report
Hello Roman,
Many thanks for great work.
I have one question regarding 2 Burson units, Conductor 3X Reference and Conductor 3X Performance. They have identical dac chip inside and identical list of filters. However, comparing the DAC filter graphs side by side, they gave confusing results. It's all mixed up. Is it really true that the AP Fast of 3X reference corresponds to MP Fast on the 3X performance? LP Fast on 3X Ref. measures like LP Slow on 3X Perf. and so on. Many thanks for the clarification.
Best regards, Bobby

Thank you. You have listed twice the same LP SLOW filter. In the manual and on the menu there is one more filter called Reserved. How does it measure?

The menu had LPSlow and LP Slow. Maybe they will make a new firmware and the names will become correct.
