        Thank-you. Measurements, data vetting, organizing, graph annotations, write-up took approximately 34 hrs, another 40 hrs spent listening, and final post was 2 hrs of effort even with everything organized in advance.

        @Luckbad - no, I've been quite satisfied with my ADI-2 Pro for work use, though now augmented with Motu UltraLite-mk4, also for work as well as recreational listening.

        Any interest in measuring an EC BW2? Mine is collecting dust in my office while I work from home due to COVID. I'd be willing to ship it to you in the name of science.

        It was disturbing but now a humorous memory. The bird was carefully brought to us without damage. I think Thomas wanted us experience the joy of hunting a bird. After release, he positioned himself where he could enjoy the show. Incredibly we were able to corral the bird and have it fly out an open window while two cats were sequestered. Both cats are my lab assistants, often sleeping near while I work.

        Whoa! I can do that kind of lab work. Even in highly-technical, specialist labs. I can send you my CV: I have slept in numerous roles from unskilled factory floor to IT management.

        But I do lack other cat-specific skills. Also no tail or fur.

        I lack the eloquence in describing the differences I hear in components with the accuracy of others on this forum. Technical differences are easily seen in the two sets of measurements. I bought the KTE Spring2 as it is close enough given my preferences and musical tastes. Also wanted to stay with a single chassis form factor.

        Our medical devices serve the pre-hospital and ER staff and their patients. During this time there has been an unprecedented demand for our devices. I am doing my part in streamlining processes such that resources may be re-deployed for faster throughput, hopefully doing my part to help serve the front line medical personnel busting butt for all of us.

    See information section for my opinions
    My enjoyment of particular recreational music systems is inextricably intertwined with my personal preferences. The following lists are representations of my tastes in music, components and listening levels. The section on music is only a sample of my library but should provide sufficient insight into my musical preferences. I am rigorous and exacting with component measurements. That doesn’t automatically make my opinions worth anything without context. Use the following information to decide how well your own preferences converge or diverge with mine when I make comments about equipment in the forum. DO NOT blindly assume a positive comment from me about some component or headphone will automatically translate to auditory happiness on your part. Likewise you may find yourself enjoying something that I don’t. Consider (learning) your own personal preference.

    90~100 Santana Black Magic Woman / Gypsy Queen, ELP Tank - drum solo

    I tend to listen at quieter levels where electroacoustic transducers exhibit greater linearity. Higher levels are more likely to have greater distortion and require higher power amplification. The result is substantial deviation in opinions by listeners attempting to compare headphones when they are listening at different levels.
