I've been MIA for over a week due to numerous maintenance issues occurring simultaneously. Individually none are that big just overwhelming. May 8, 2022

        Issues and problems are resolving. It was overwhelming to have so many occur in rapid succession in a short span of time. Digging out, things are better. Still, my issues pale in comparison to those experiencing madness of war, or fighting chronic illness.

        After seven decades I have done many things and hope they are of service to the world in general. Many of my audio endeavors were to refine my understanding of communication, especially during acute events when lives hang in the balance. Surprising the level of overlap between musical endeavors and critical communication.

        Honestly, always learning interesting new things is an excellent way to spend time on-planet. Tried Resolve after an art Youtuber I follow plugged it and the learning curve is a bit steep, but probably nowhere near so much as some of the lab gear you run on a regular basis. Hope it's fun!

        I was very fortunate. SMART provided warning of imminent failure due to error 204, Bad Block Full Flag. Acronis full backup to NAS for 220 GB took about 3 hrs. Data migration took about 21 minutes to new drive. Biggest delays were shipping and me attempting to be too clever. 2 perfectly fine days shot to hell with no lab computer.

    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.

    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.
