It has been quite some time since my last article for Positive Feedback about the Sophia Electric vacuum tubes developed and offered by Sue and Richard in McLean, Virginia. It was all the way back in August of 2017 that I wrote about the Sophia Electric EL34-ST (photo below) and Aqua 274B vacuum tubes (HERE),... Read More »

I've had my Leben HiFi Company CS-600 integrated amplifier for over a decade now. I purchased it after the review, and I have enjoyed every minute with it. My Leben CS-600 has been totally reliable, excels musically & sonically, and it is beautiful to look at. The CS-600 was also a very well thought out... Read More »

At the enthusiast audio shows I have visited in the USA over the years, I've always thought that year-to-year, the Audio Note (UK) rooms had some of most consistently excellent musicality & sonics of all the show rooms I visited. The fact that those Audio Note (UK) show rooms utilized relatively modestly priced equipment and... Read More »

In my last Today's Fresh Catch post (HERE) I mentioned the variety of NOS 12AT7 signal tubes and NOS rectifiers that I had purchased from Radio Electric Supply to try in my Leben RS-30EQ:

One of the favorite pastimes of many original Leben CS-600 integrated amplifier owners has been trying different combinations of vacuum tubes in their CS-600 to tailor its sound to what best matches their personal taste.

Wow, I am amazed at the amount of people writing to me and asking me about the new Leben CS600X that just arrived here at Jeff's Place, and how it compares to my original CS600 - there's a lot of you Leben fans out there!

I was quite excited when I received notice from Positive Feedback Editor Doc David that there was a Pass Labs XA25 Class A stereo amplifier available for me to write about for Positive Feedback (photo below). I had been mightily impressed with the 18 watt per channel (into 8 Ohms) First Watt SIT-3 single-ended amplifier... Read More »

This particular feature article for Positive Feedback isn't your typical audio review, but rather is intended to be a fun and inspirational "dare to dream" article that is decidedly outside of the usual audio mainstream. This is an article that tells the story of the successful marriage of the latest state-of-art Duelund Coherent Audio CAST... Read More »

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,

Welcome to Hanze HiFi! I always enjoy telling you about the people behind high-performance audio products and HiFi shops, as quite often they are the most insightful and informed of all enthusiasts about HiFi, telling us about new and exciting audio advancements, and possessing a zeal and vision that drives audio performance to that next...

The Hanze HiFi HAT turntable power supply is beautifully built, and provided meaningful but subtle improvements to my CTC Garrard 301 turntable's performance in terms of overall musicality and sonics, making everything sound and feel a little bit better, more emotionally engaging, and more like what I hear and feel from a live music listening experience.

As you know if you've been reading along, I've been experimenting with different combinations of the Duelund DCA tinned-copper tone cables for the Duelund-Altec Project (HERE), both as speaker cables and for connecting the Duelund CAST tinned-copper crossovers to the Altec 804A 16-Ohm compression drivers.

I've always thought of the Thorens TD-124 as one of the most beautiful of the classic turntables, which for whatever reason, reminds me of being the 1955 Ford T-Bird of the turntable world, a classic car which I also happen to greatly admire. Artisan Fidelity Thorens TD-124 Statement / Classic Long-Base Turntable I had lusted... Read More »

The fifth week of listening to the Duelund-Altec Project's state-of-art Duelund CAST tinned-copper crossovers with the vintage "Stokowski" Altec's brought momentous changes in what I was hearing, and in a very satisfying way both musically and sonically.

When I say “HiFi system voicing” you might wonder what I’m referring to. Basically, I’m referring to what any given hifi system sounds like in terms of its particular blend of musicality and audiophile-style sonics, or its overall sound quality.

It sure is delight to be up and running here on Jeff's Place at Positive Feedback for 2019, and I'm "sharpening up my pencil" now to do a little writing about music, hifi, and other stuff for you!

I first became aware of Mr. Ken Ishiguro's Acoustic Revive products in 2007 when they were recommended to me by Mr. Yoshi Hontani (The MuSon Project, Osaka, Japan), who exports hifi exotica from the Leben Hi-Fi Stereo Company, the Spec Corporation, fo. Q, Audio Replas, KRYNA, SFORZAT, Murasakino Ltd, and of course, the subject of this article, Acoustic Revive.  This is Chapter... Read More »

If you read Parts 1 and 2 of my Soundsmith review series in Positive Feedback Issue 98, where I wrote about the new Carmen Mk II (HERE) and new Zephyr Mk III (HERE) phonograph cartridges, you know that I found Peter Ledermann's designs to be among the most musically satisfying phonograph cartridges I have ever...

When Mark Still contacted me in June about reviewing his handcrafted Still Audio EL84 integrated amplifier (below) I was immediately intrigued, particularly when Mark urged me to give it a try with my pair of vintage Altec 832A Corona loudspeakers, whose visceral musicality I adore. I was impressed with Mark's chassis design for his Still... Read More »
