The Vintage McIntosh Resistor Adventure Continues (and other stuff)!

While doing the vintage McIntosh MX110 tuner-preamplifier adventure we experimented with several brands of new & NOS metal film resistors in the circuit in various places, but basically I always ended up preferring the vintage 2-watt NOS Allen Bradley carbon comp resistors that Andy Moore had suggested I try. The vintage 2-watt NOS Allen Bradley resistors had better tone,... Read More »

Jeff checking in ... a look into the crystal ball: the past, present, and future!

The Vintage Beat It sure has been a wonderful experience dipping my toe into the waters of vintage hi-fi gear, like with my original Garrard Project (1, 2, 3) articles: Or with my restored vintage McIntosh kit like the MX110Z tuner-preamplifier, stereo MC240 amplifier, stereo MC225 amplifier, and MC30 monaural amplifiers: Or the world of vintage...

The Vintage McIntosh MX110 Tuner-Preamplifier Adventure: The Arizona Capacitor Palette!

A good alternate title for this post would have been "The Real Sound Education of Jeff Day" because that is the result of Yazaki-san's and Ron-san's influence on me during our mutual adventures with the vintage McIntosh vacuum tube gear. Due to Ron's influence, I have now made the transition of being a modification observer... Read More »

The Vintage McIntosh MX110 Tuner-Preamplifier Adventure: The Tepro Transformation!

Have you ever woken up in the middle of the night with a major revelation? In my case my major revelation came at 2:53 a.m. last night, according to the screen on my iPhone. It was three thoughts coming together that triggered my overall revelation, but I want to tell you the story in the sequence that it occurred... Read More »

Jeff checking in ... Arizona Capacitors, Tepro, Schick re-wire, and music!

Ron, Leo, and I got together to do a little listening to a variety of vintage preamplifiers last weekend, the Audio Research SP-6B, the Harmon Kardon Citation 1, and the McIntosh MX110.

The MX110 and Saturday Morning Soldering - the Oddio Resistance!

I was so pleased with my vintage McIntosh MX110 tuner-preamplifier 'resistor adventure' this morning I just had to tell you about it! As you know, the MX110 Adventure has thrown us a few unexpected curve balls, and in response Ron-san and I have been going through component-by-component to figure out what was going on and...

Reflections on Music & Hi-Fi

It was a lot of fun to have Rafe (Part-Time Audiophile) and Don visit Jeff's Place over the weekend, and we covered a lot of ground musically, sonically, and philosophically. From a musical perspective we did a little bit of a survey of the recording arts, starting with some very early mono recordings, progressing through... Read More »

The Vintage McIntosh MX110 Adventure: Allen Bradley & the Naked Ladies

If you've been reading along about our real sound adventures with my vintage McIntosh MX110Z tuner-preamplifier, you know the modifications we did threw us a curve ball, and the resulting performance after our modifications didn't sound nearly as good as my stock MX110Z. Argh! While there were some promising aspects to the performance of my modified MX110Z, we basically struck... Read More »

The Power of the Orchestra!

Normally when I hear the phrase 'The Power of the Orchestra' it makes me think of the famous Kingsway Hall recording by Kenneth Wilkinson of René Leibowitz conducting The Royal Philharmonic Orchestra playing Pictures At An Exhibition & Night On Bare Mountain (RCA VCS-2659), which has long been on Harry Pearson's Super LP List, and renowned for its remarkable dynamics,...

Well how do I say this? Things haven't gone so well with our... Read More »

A Listening Adventure: A Trio of Modified Vintage McIntosh MX110 Tuner-Preamplifiers

Ron, Leo, and I got together last weekend to listen to a trio of vintage McIntosh MX110s variously modified by Ron-san with Real Sound modifications as suggested by Yazaki-san, which are similar to the modifications Yazaki-san has performed on his personal vintage Marantz 7 preamplifier. Prior to being modified by Ron-san, two of the MX110s were restored -... Read More »

Morning Coffee with the Maestro's VOTTs & Thoughts on Vintage Tone

My Maestro's VOTTs & SPEC RSA-M3 EX Real Sound Amplifier room has become my go-to coffee nook in the morning. I've developed a week-day ritual of rolling out about 4:30 a.m. and firing up the SPEC RSA-M3 EX, the Mhdt Paradisea+ USB DAC, and my old MacBook that I'm using as a source. Then I wander into the kitchen to... Read More »

A Real Sound Adventure With the Vintage McIntosh MX110Z

If you read The Vintage McIntosh Experience article in Issue 77 of Positive Feedback you know I'm a big fan of the vintage McIntosh MX110Z tuner-preamplifier. The MX110Z makes vinyl & FM sound astonishingly good, it even makes digital your friend. Performance-wise it can easily hold its own against contemporary preamplifiers, and feature-wise it outclasses any modern preamplifier on... Read More »

Western Electric WE16GA Power Cords for the Vintage McIntosh MC30 Monaural Amplifiers

A couple of posts ago I told you about my adventure of building up an AC power cord with the Western Electric WE16GA and trying it out on my Mhdt Havana USB DAC. It takes a while for the Western Electric WE16GA to settle down, but I thought my newly constructed WE16GA power cord sounded promising, and... Read More »

Due to your critical acclaim, the Jeff's Place Readers' Choice Award unanimously goes to Mr. Shirokazu Yazaki's 'Real Sound' recommendations for the Western Electric WE16GA wire and the Belden 8402 microphone cable.
