Default Another Electra 7...same application in a different system

In a sense, my home-office system is the neglected audio stepchild of the family. That’s not the fault of the eBay-acquired Sonographe electronics or the dealer’s closing-up-shop demo Paradigm mini-speakers--overachievers in all cases, certainly at the prices I paid for them. The problem is the space they’re crammed into—a 12’x10’ room stuffed with a computer station, printer table, a single bed, a number of bookcases, and protruding closet, whose location and layout render anything approaching a reasonable listening venue a forget-about-it pipe dream. Listening is extreme nearfield, and “extreme” puts it mildly—when at the computer, I’m parked about a foot in front of the speaker plane, while the center-to-center distance between the left and right speakers is about five feet.

The system’s sole program source is, like the bedroom system’s, an external hard drive feeding a Windows 10 desktop computer running JRiver Music Center software. Music files consist of CD rips and hi-rez downloads ranging from 24/88 to double-DSD and DXD. This work station is where I download and rip all of them before I shoot them across the home network to the main and bedroom systems. Because of that, the office system is, despite its severe environmental limitations, the place where I initially listen and evaluate all rips and downloads to determine whether they “cut it” for further use.

Up until a couple of weeks ago, the system’s sound “engine” was the factory-installed sound card in the HP desktop. That restricted hi-rez playback to a maximum of 24/192, forcing me to configure JRiver to downconvert higher-resolution PCM and all DSD files for listening in the office system—not ideal for initial-evaluation listening. Off I went to eBay again and scooped up a comfortably-priced mint-condition TEAC UD-501 DAC (just like the ones in the main and bedroom systems). It came with a stock AC power cord.

Based on my happiness-is experience with an upgraded-connector Wireworld Electra 7 PC in the bedroom system (and it’s just gotten better with more burn-in), I thought “why not?” and ordered another one from he-who-treats-us-AA’ers-so-well. As much as anything else, I was curious about whether, given the sardine-can listening environment, the Electra 7 would make an appreciable difference in what I’m hearing from the office system. If it didn’t, I’d move the new Electra to an identical role in the much more acoustically hospitable main system.

The Electra arrived today, and I have just about two hours of playing time on it as I write this. So it’s not burned in, and I don’t know if it’s “settled” yet. But none of that matters. The Electra stays feeding AC to the home-office UD-501.

Even in this cramped listening space, the Electra 7’s superiority over a stock cord is as noticeably pronounced as it was in the bedroom system—in focus, bottom-end heft, dynamics, top-end liquidity, and tonal/timbral rightness…and in whatever program material I throw at it (not least “The Masque” from Lenny Bernstein’s recording of his “Age of Anxiety”). The Electra doesn’t repeal the laws of room acoustics—certainly not at one foot in front of the speaker plane--but even so, the discernibly blacker background teases out more spatial detail and instrumental and vocal layering.

That settles it. Starting today, I’m saving up for one more Electra with the upgraded connectors…for the main system’s DAC. I'll be in touch, Ivan.
