This is just a quick shot of 4 different op-amp setups in my E12 DIY with a FiiO X5k as DAC. Using 2x AD797, 1x AD8620, 1x Burson V5i and OPA1611 op-amps in the E12. While capturing all the signals live with my Hitachi V-1065 (100Mhz) oscilloscope. The song is by Eric Lindell (all rights reserved) titled “Lullaby For Mercy Ann” in 16bit 44.2kHz FLAC.

The audio is not what is important, but it is to ensure you are seeing it in sync. However, the quality is terrible by a camera recording headphones. This is not meant to be a music video in the slightest. This video is meant to be an update to show people what I am up to and to let everyone know my Audeze EL-8 open-backs just arrived! Now the real testing begins! Pause this video frequently and analyze the differences in the signals. I found it interesting when trying to quantify what I am hearing and describing in words vs. what I am seeing on the display of the stereo signal.
This video is meant for scientific/educational purposes and to let people know their 1970-1980 oscilloscopes can still play a role in analyzing hardware in 2016. Stay tuned for my review and more projects are in the works as I speak!
