JE Labs Man Cave 2024


This is the side of the man cave where I spend a lot of time listening and evaluating new projects.

In the coming months, I will be talking about phono preamps, autoformer volume control, revisit the transformer coupled line stage topology, SE amps, etc. I will also continue my classic Japanese idler-driven turntable series, feature a couple of SE-DHT amp-friendly drivers + more.

Most of the audio components listed below are hyperlinked if you mouse over the text. Those that are not will be linked once the article is uploaded.

I like to taste new sonic flavors that are within the DIY realm😊

OJAS Listening Room @ USM in SoHo NYC

I never imagined 30 years after the late Don Garber closed his Fi audio gallery at 30 Watts Street, that there would be a similar gallery in SoHo NYC again.

In the summer of 2022, I visited Devon Turnbull's OJAS exhibit at the NYC Lisson gallery. Click here to read about it. This past summer, a similar exhibit was presented at the London Lisson gallery

As soon as the London exhibit concluded, Ken Micallef, whom I follow on YouTubeuploaded this video featuring OJAS hifi systems inside a posh SoHo boutique. This was the main motivation to add it to my list of must-see places on my next NYC trip! 

Without further ado, here's what Tish and I experienced when we visited in mid November 2023.

A Cousin's Listening Room

 

This is a hifi system I built for a cousin who loves music!

The speakers, which I dubbed Altec 753C, is the culmination of my Altec 2-way horn system project.

Western Electric 753 inspired cabinets meticulously handcrafted by John Piro of Hommage Audio

Garrard 301 turntable + Ortofon RMG309i tonearm + Ortofon SPU Synergy for stereo LPs and Alfred Bokrand AB309 + SPU Mono for mono LPs

The JE Labs preamp line stage is a plate choke loaded 76 while the SE300B mono block amps feature a Komuro-inspired circuit using type 37 input tubes + Intact Audio nickel plate choke loaded 6V6s or 6F6Gs (connected in triode) and Hashimoto H-30-3.5S output transformers.

Projects like this keep me busy during the pandemic.😊

man cave 2021

 

From mid September until mid November, the man cave was out of commission so I set up a temporary system in our living room. 


Flooding in the lower level had been a major issue since we moved to this house. Tish and I finally bit the bullet and had a French drain + sump pump system installed.


Knowing that jackhammers would create a big mess, we packed up all of our books, LPs, CDs, etc.


I had to repaint/reseal the floor because it was badly scratched by contractor traffic.

At least 12 square feet of floor space was gained from the removal of a built-in bench. We reclaimed a small window that had been blocked off, which most likely had an a/c in the past.

Still working on the main hifi system and filing my LPs...πŸ˜‰

I'm really liking the less cluttered look, which means I have to reduce my audio collection. So keep your eyes peeled for goodies at the JE Labs Flea Market after the New Year. πŸ˜„

JE Labs Man Cave 2020



CV21mm f4

The JE Labs man cave was originally planned as an annual feature. But due to a flood mitigation procedure in the fall of 2019, I blogged about the near-field system instead. 

Fortunately, a new drywall was installed and painted by the tail end of winter. I was at the final stage of arranging my library, cameras, LPs and miscellaneous items when lockdown commenced.  

Typically, I'd be on photo explorations in my spare time during spring. But due to the pandemic, I'm trying to be a responsible citizen practicing social distancing. Since I'm confined indoors, here's a virtual tour of the man cave viewed through my Leitz and Cosina-Voigtlander lenses mounted on a Sony A7II camera.

JE Labs Audio Playground AKA System No. 2

 My main system has remained pretty constant for over 20 years, except for a couple of milestones. However, the same can't be said about my audio playground which sits beside my home office, in which the only thing constant is change. πŸ˜‰


 Testing a few flea market/thrift store finds: a Kenwood KT880D tuner, a Sony DVP NS900V, a Magnavox CD2000, comparing a pair of Electro-Voice Sonocaster portable speakers vs. Lafayette SK98s, revisiting a Rek O Kut L34 + S160 tonearm + Shure M3D 
The power amp is my JEL Simple 45 with Tamura F475s driven by the JEL Loctal Preamp.


Trying a pair of Sansui T-104 horn tweeters on top of Altec 755Cs in Altec 618 cabinets, Denon DP1250 + Rega R200 tonearm + Audio-Technica AT3600L, comparing the Scott LT110B vs. the Kenwood KT880D vs. the Yamaha T-2


Since I blogged about the Altec 755A in Dr. Bae/Silbatone cabinets, this system has remained pretty consistent with a Gates CB77 + Fidelity Research FR54 + DL103 + Shure MC transformers or a moving permalloy Nagaoka MP10 serving LPs + the JEL Loctal Preamp  and JEL Simple 46 or Dyna ST35 doing preamp/amp duties.

This system also served as a cross reference for the  CD/DAC mods, Multi-bit DACs, Thrift Store CD players, Darling Amp, JEL StyleFM Tuner reviews, amongst others that I blogged about this past year.


At the end of summer, the boss decided that it was time to mitigate the flooding problem during heavy rain and snow in the lower level of our home. 


Since this entailed removing the drywall in the hifi man cave, everything had to be stored or relocated and dust-proofed. 


It's been over a month since the retaining wall was sealed with waterproof coating. We've had a couple of strong rains and it's been dry so far. But we're in no hurry to replace the drywall. We want to make sure that it'll stay dry through the worst precipitation Mother Nature sends our way.

Meanwhile, even if I have a nice mono hi-fi in the living room, I miss stereophonic sound.


The boss was kind enough to allow the re-commissioning of the near-field system. To make unpacking simpler, I minimized the use of tube electronics. 

I'm currently DJ'ing between a Denon DP1250 + DA50 and a Sony TTS2500 + Grace G565 with various MM and MC cartridges. Line level sources include a Raspberry Pi 3B+/Volumio > Musical Fidelity V-Link USB to S/PDIF* > NOS'd Arcam Delta Black Box DAC and an NAD 4300 AM/FM tuner.

*I acquired this for less than half the cost of an Allo DigiOne and it sounds just as good!


A Realistic 32-1100A Stereo Mixer I found at a flea market for 10 bucks is doing preamp duty. It has provisions for three line level inputs or 2 x magnetic phono + 1 line level. I thought the magnetic phono inputs were pretty decent on this discrete transistorized unit (no op-amps) until I got another discrete solid-state Radio Shack product, the 42-2109 phono preamp. This unit produced a warmer, more vivid midrange with even better extension in the frequency extremes. 


To warm things up further, I inserted a pair of UTC A20 line level transformers between the Rat Shack Stereo Mixer and the Nobsound NS-02g

Belden 9497

The Belden 9497 speaker cables softened the slight edginess betraying the solid-state DNA of the JLH 1969 Class A amp clone and made the Altec 755Cs in Altec 618 cabinets sound snappy!


Judicious mixing and matching of yesteryears' solid-state audio components employing discrete circuitry with the line transformers and a cable tweak inserted in between, mimicked the musical experience I typically enjoy only from an all vacuum tube set up. It's akin to the Fuji Acros film simulation setting in my Fuji X-E3 camera. But there's still no substitute for the real thing. πŸ˜‰
