A Shielded Duelund DCA26GA Interconnect for Sunday!

This morning I built a 1-meter shielded Duelund DCA26GA tinned-copper interconnect (shield connected at source end) to connect the 2-Ohm version of the Arai Lab MT-1 SUT that I am currently reviewing for Positive Feedback to my vintage MX110Z preamplifier’s phono stage. I now have shielded versions of the DCA16GA, DCA20GA, and DCA26GA tinned-copper interconnects […]

Jeff checking in: Guitars, Duelund, Thorens, Arai Lab MT-1, Audio MusiKraft, and more!

Man, the last couple of weeks have been rough. A kidney stone that seems to think that playing hide and seek with me is a fun thing to do has been keeping me under the weather a bit, and as a result I haven’t got nearly as much written as I like to. No worries […]

Jeff checking in: Thorens TD124, Sophia Electric, Duelund DCA ... and more!

Last weekend was a rough one. I was felled by a kidney stone on Sunday, which earned me a ride in an ambulance to the emergency room. The little bugger hasn’t passed through yet, and still has some fight left in it, which it has been keen to remind me of from time to time. Ugh. I’ve […]

Duelund DCA26GA Tinned-Copper Interconnects for a Saturday Afternoon!

As I mentioned in a post about 3 weeks ago, I built up a set of 1.5 meter Duelund DCA26GA interconnects terminated with Switchcraft RCA’s. I’ve been listening to the Duelund DCA26GA IC’s with the Switchcraft RCA’s on my OPPO UDP-203 Blu-ray player, and I’ve been impressed with how good they sounded in that application. I had presumed that […]

The Sophia Electric EL34-ST and Aqua 274B Vacuum Tubes Review is Now Live at Positive Feedback!

I wrote all day yesterday and finished up the review of the Sophia Electric EL34-ST and Aqua 274B vacuum tubes. The Sophia Electric EL34-ST power tubes (above) and Aqua 274B rectifiers (below) outperformed everything that’s ever graced my Leben CS-600 integrated amplifier, and vintage McIntosh MC30 monaural amplifiers, respectively, and by a large margin. I don’t […]

A Thorens TD124 Project for 2017!

I’m really excited about a very special Thorens TD124 restoration and ‘hot-rod’ project I commissioned with Christopher Thornton of Artisan Fidelity. The completed Artisan Fidelity TD124 Statement turntable will look similar to the photo below, but will have a “long-base” plinth that is about three inches wider to accommodate my preferred 12-inch tonearm. Christopher just sent me some […]

Quieting Down a Noisy Vintage McIntosh MX110Z Volume Potentiometer

I have access to buying almost anything as an audio writer, and there’s some really nice audio gear out there, but for a preamplifier I chose the vintage McIntosh MX110Z tuner-preamplifier, which was sold by McIntosh from 1962-1969 for the lofty price of $399. The reason is that the vintage McIntosh MX110Z tuner-preamplifier is an […]
