Jeff Checking In: Acoustic Revive, Audio Note (UK), iPhone Adventure, audio centrism or audio relativism (?), and other stuff!


Greetings friends, I hope you are doing well! 🙂  I love getting out on two wheels for a little exercise (bicycles) and a little exploring (motorbikes).

Greetings friends, I hope you are doing great!  Life just seems to keep getting busier, but in good ways.  As I transition into the Winter months my activities tend to shift from outside to inside.

Greetings friends, I hope you are doing well! The dark winter months of January and February are tough for a lot of us.

Jeff checking in: "Hello, goodbye" with Audio Note (UK); and more (updated)!


Greetings friends, I hope you are doing well! I was just telling my Facebook pals about the weird Fall weather we have been having here in the Pacific Northwest.

Jeff checking in ... back in the saddle, Audio Note (UK), Duelund Coherent Audio, Sophia Electric, and more!


Greetings friends, I hope you are doing well! I'm starting to feel better now, and am back in the saddle after recovering from a recent surgery.

Murphy's Law has been going full steam ahead in my life lately, it seems, with a series of Murphy-like disasters shuffling aside my plans for some travel and adventure on a motorcycle tour through Eastern Washington, Northern Idaho, and Western Montana, that I had scheduled for this week. While I wait for life's positive vibes... Read More »


Jeff checking in: Amplifier heaven, listening to great Class A amplifiers, and an exciting upcoming amplifier project!


A couple of good friends - Leo and Santos - stopped by for a little "single-ended-triode (SET) amplifier and wine tasting event" here at Jeff's Place.    It's always fun to get together with good friends like Leo and Santos for a little wine tasting, single-ended-triode amplifier 'tasting', good food, and good music. It's the perfect way...

Greetings friends, I hope you are doing well. It seems like my audio list of topics to write about just keeps growing, and at times I ponder how I'll be able to keep up with everything going on.

Jeff checking in: What was, what is, and what is to come!


Greetings friends, I hope you are doing well. I always get retrospective in the closing months of a year, looking to the past, and giving consideration to where I'm at in life, while I try to 'crystal ball' my best guess for what the future holds.  There's been so much change in my life over...

With 2020 in the rearview mirror, I had hoped 2021 would usher in a reprieve from our troubled world, but it was not to be.
