First Listen - The Audio Note UK Oto Phono SE Signature Integrated Amplifier, Part 2!
As I was casually listening to Jazz24 while doing a few things around the house, I was rather struck by how musical the Audio Note UK Oto Phono SE Signature integrated amplifier was sounding through its "CD" line input, how it always seemed to tug at my attention and pull me into the music regardless...

I go through the same procedure as I did as a kid during Christmas time when checking out presents under the Christmas tree. I picked up my presents, considered their weight and size,... Read More »

Other Stuff: Peter Qvortrup's reading list for me!
You might have noticed that below my Jeff's Place title that it says that my blog is about "Music, Hi-Fi, and Other Stuff". That's because Jeff's Place is my personal blog about music, hi-fi, and other stuff, with the "other stuff" being miscellaneous things that are on my mind that I want to write about that...

It was a really enjoyable Friday this week, with a splendid visit from Paul James, who came all the way from Australia to visit Jeff's Place.

The Pass Labs XA25 stereo amplifier: Listening Impressions and Chatting with Nelson Pass!
I've been putting a lot of run-in and listening time on the Pass Labs XA25 stereo amplifier since it arrived, to the extent that I've lost track of the number of hours on it.

2019 DIY Burning Amp Festival, San Francisco, Nov. 9th & 10th
Normally I don't pass on press releases, as that's something that Positive Feedback issues in their "Industry News" section, but in this case - because of my (and your) interest in DIY audio - I thought I'd let you know about this one to give it some extra emphasis. Nelson Pass is really into DIY, and this... Read More »

Today's Fresh Catch: Amy's Amplifier - The Audio Note UK Oto Phono SE Signature Integrated Amplifier
One of the things that I observed - and very much appreciated - about Audio Note UK while I was visiting was that it is very much a family oriented business, with Peter Qvortrup, Lesley Fennell (Peter's wife), Emily Qvortrup (Peter's eldest daughter), and Daniel Qvortrup (Peter's son) all being involved in the day-to-day business...

The Duelund-Altec Project: Update x 4 and final step!
It's been a long road from the conception of the idea of building custom state-of-art Duelund CAST tinned-copper crossovers with Frederik Carøe of Duelund Coherent Audio for the historically important vintage - and state-of-art for their time period - "Stokowski" Altec loudspeakers that were custom built for conductor Leopold Stokowski back in the early 1960s...

Jeff checking in ... visiting with Peter Qvortrup of Audio Note UK! Part 4.

Jeff checking in ... visiting with Peter Qvortrup of Audio Note UK! Part 3.
My jet-lag upon returning home from visiting Peter is getting a little better each day, and I actually stayed awake until 8 PM last night, but alas, I awoke at 1:30 AM wide awake.

Jeff checking in ... visiting with Peter Qvortrup of Audio Note UK! Part 2.
Jet-lag doesn't affect me as much when I travel to the UK or EU as it does returning home to Jeff's Place in Washington State of the USA. I'm not sure why that is so, but I suspect it has to do with my excitement surrounding travel, getting to my destination, and the new adventures that await... Read More »

Jeff checking in ... the Duelund-Altec Project, musical chairs with Pass Labs & First Watt stereo amplifiers, and enjoying the company of friends!
The Duelund-Altec Project is really something special, a lot of fun, and it's definitely not your typical audio project or review, but rather is intended to be more of a "dream" article that is decidedly outside of the usual audio mainstream, one that involves a story about the marriage of the historically important vintage Altec...

First Listen: The new Duelund plastic-free RCA's & DCA16GA interconnects!
I told you about the new pre-assembled Duelund Coherent Audio DCA16GA tinned-copper interconnects in my last "Today's Fresh Catch" post (HERE).

Altec dreams ... and what sweet dreams they are!
I've gone completely bonkers over vintage Altec loudspeakers, which comes as no surprise to you if you're a regular reader of Jeff's Place. It's not that there aren't other speakers I enjoy listening to, like my Westminster's, for example, but there's just something really special about the way Altec loudspeakers play the music. Ok, so... Read More »
