Today's Fresh Catch: The Luxman AS-4III Line Selector - Update.
My vintage MX110Z tuner preamplifier has two phono inputs, which is not enough to accomodate the three tonearms I have in play on my Thorens TD-124 and Classic 301. I've got the Audio MusiKraft Denon DL-103 / Schick tonearm / Auditorium 23 SUT going into one phono input, and my Ortofon SPU Classic GM MkII stereo... Read More »

Kara Chaffee (deHavilland Electric Amplifier Company) was over visiting Pete Riggle (Pete Riggle Audio Engineering) for an impromptu audio fest, and brought along her prototype Super 40 monaural power amplifiers for a little listening.

First Tune: A Tunable Adventure with the Audio MusiKraft Denon DL-103 Phono Cartridge! Updated.
Sometimes the best laid plans just don't pan out the way you think they will.

Long Term Report: My 2015 Garrard Project in 2017!
In my original "Garrard Project" back in 2004, I started with a nice old original 301 in a simple plinth, and built it up into a music-making machine - the results were superb!

The Thorens TD124 and the Acoustic Revive RAS-14-TripleC NCF Power Stabilizer!
The other day I was thinking about what Mark Coles (Sablon Audio) had told me about how a quality AC power cord noticeably improved the sound of a turntable. Improving a system's sound by using a high-performance AC power cord on the turntable wasn't an intuitive hot-rod mod for me, and I sort of wondered if... Read More »

Revisiting an old friend: The Denon DL-103 MC Phonograph Cartridge
It's been quite a while since I've given my Denon DL-103 MC phonograph cartridge a good listen, so I thought I'd get the Denon out, mount it up, and play some music.

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... Read More »
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... Read More »
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 don't... Read More »
A little live music for a Saturday morning! Guitars and more!
