Hot Tip!!! DIY audio (RCA/phono) interconnects
What to use:
WIRE: I use JSC Wire--Multi-Conductor
Overall Foil Shield 75°C, 300 V, PE Insulation (the version shown here is more than two conductors)...
...which I get at the
local electronics-parts store. It's good enough for most industrial and residential
applications and far from being cheap-grade. I also use Canare microphone
or coaxial cable; I don't think this more-expensive, audio-app-specific wire
is better than JSC.
PHONO (RCA) CONNECTORS: Neutrik, Switchcraft, Canare, etc.
OTHER: Heatshink tubing; high-quality (silver) solder
How to wire: Blue is signal - tip on plug; Screen (shield) is return (ground) - outer on plug. So, how about white? Wire it to the outer at the signal (source) end only, making the cable "directional".
References: audioasylum thread
Shown below: inexpensive but effective Switchcraft 3502 RCA plug...

QUESTION: Why resurrect old equipment reviews?
ONE SIMPLE ANSWER: To keep the industry in check.
Old-is-new trends are common in all eras, gadget genres, and formats.
Gear "collectors" may be motivated by nostalgia or boredom or re-sale value (eBay stores)... but let's set these excuses aside, and simply ask this fundamental question:
How much technical progress has really been made in audio science and engineering -- that is, does modern equipment really sound better?
Is there such a thing as "timeless high-fidelity?" Perhaps, yes, if one is talking about: vinyl on classic Thorens turntables, played on decades-old electrostatic and horn loudspeakers, and (of course) through vintage vacuum-tube gear. This old stuff, when functioning properly and reliably (and maybe restored), can directly compete with many contemporary models.
Much old gear can be found on eBay and Craig’s List for considerably less money than band new (or even used-but-modern equipment, as in the overpriced used/2nd hand/trade-in section of hi-fi shops).
Knowing when to invest in old gear takes practice and skill (sometimes literally: as in using a soldering iron!). But the economic and self-accomplishment rewards are well worth it! You many never buy new gear again!
Headphones:
Electrodynamic / Orthodynamic: (aka planar magnetic, like Audeze brand)
This type of headphone is essentially in the same family as the moving-coil type, except that the coil has, in effect, been unwound and fixed to a thin, light, plastics diaphragm.
The annular magnetic gap has been replaced by opposing bar magnets, which cause the magnetic field to be squashed more or less parallel to the diaphragm. The " coil " is in fact now a thin conductor zig-zagging or spiraling its way across the surface of the diaphragm, oriented at right angles to the magnetic field so that sending a constant direct current through the conductor results in a more or less equal unidirectional force, which displaces the diaphragm from its rest position. An alternating music signal therefore causes the diaphragm to vibrate in sympathy with it, creating a sound-wave analogue of the music. (read more...)
