Performance depends on the room complexity
+ Room optimization sofware does dampen a few of the modal issues. Global mode seems to work the best in regular mixing situations.
+ DA converters are of decent quality.
+ Simple rooms (simple geometry, little furniture) show the most noticable results. In a 4x5x2.5m bedroom studio, the Ergo did produce a noticable difference between Focus, Global and Bypass mode.
- Complex rooms (asymmetric walls or with interfering furniture) show little or no improvement beyond placebo.
- Even after several firmware updates (latest at test time: v1.32.24), the ticking sound when adjusting the volume is still not solved completely.
- Phase response and stereo imaging is not noticably improved, probably due to the optimization only working on frequencies below 500Hz.
- A slow sine sweep after optimization revealed that one of the modal nulls is being corrected to the point of distortion (a clipping sound that resembles scraping the strings of a cello). Less of a problem in Global mode than in Focus mode.
Ease of Use:
+ No need for a degree in acoustics in order to use the device. Well-guided setup process.
+ Easy to operate controls during everyday use.
- Excruciating sound intensity during calibration measurements. Give your neighbors a notice that they should hide their pets! Makes you consider it as a high risk, if you have to take extra measurements or recalibrate the Ergo.
- Before calibration, you're asked to raise the volume up until the background noise is at a certain level (or when infra/ultrasound is above the background noise, I can't really tell what's being done). There is no user feedback on the signal that's measured, just instructions. So if you make a rookie mistake or use a bad cable when connecting your microphone, your eardrums will shatter as soon as the calibration starts.
+ Impressive amount of hardware features. Has basically every feature that is expected for a typical bedroom studio monitor controller.
- The room optimization is a black box. You must accept the results of the measurements with three options: Focus, Global, or Bypass. No other configurations possible, unless you want to recalibrate. But how do you know what to fix in your room before recalibrating?
- FireWire limits the user base somewhat.
Bang for buck:
+ Many features for a decent price
+ Measurement microphone and XLR-jack adapter included. Can be used as a regular SDC omni microphone, nice for recording ambience.
- Might not be efficient in your room. Makes a good case for why acoustic treatment is a better investment.
