Consider Connectors

“God is in the detail” – Ludwig Mies van der Rohe (et al)

Sometimes it’s necessary to re-examine the little things, the forgotten details.  Try to dig out the last 10% improvement.

Consider amplifier and loudspeaker connectors.

We know that music signals are alternating current, AC not DC – swinging positive/negative.  We know also that “current in a conductor resides at the surface at high frequency” (Prof. Malcolm Hawksford, HFNRR Aug 1985):

Skin-Depth

The upper frequencies in particular, of music signals, tend to flow near the surface of a conductor.  At 20,000Hz ‘skin depth’ is only around 0.5mm.

Compare the above to the smooth, direct signal path in the Eichmann (or ETI) Cable Pod binding post design (below):

The Eichmann (or ETI) RCA Bullet Plug (below) is a similarly excellent design – minimal metal mass conductors, smooth/short signal path, no unnecessary conductive outer metal parts, copper (or silver) centre pin conductor, single-pin contacts.

WBT NextGen and Furutech also offer excellent connectors, similar in principle, but generally more costly.

Audible sonic benefits?

Eichmann Bullet Plugs:  More of everything.  More natural tone, dynamic agility, detail, soundstage clues, layering.

No sense in compromising a fine amplifer or loudspeaker, by employing cheap or poorly deisgned connector plugs and sockets.
