KLEI Absolute®Harmony Phono/RCA plugs by Neville Roberts (Hi-Fi Choice/UK)

Verdict★★★★☆

KEITH LOUIS EICHMANN of KLEInnovations has released a fourth member of his Harmony series of RCA plugs. This new entry slides in above the previous top-of-the-range plug, the KLEI Pure®Harmony RCA plugs.

The range is a replacement for the legendary Eichmann Bullet that Keith designed over 15 years ago, which also features a single-point ground/earth/return contact.

As with the KLEI Pure®Harmony RCA plugs, the KLEI Absolute®Harmony RCA plugs signal and earth pins are made from a proprietary silver alloy that has >106% IACS conductivity (relative to 100% IACS, the International Annealed Copper Standard).

The KLEI Absolute®Harmony RCA plugs, however, utilise an even higher spec KLEI PureSilver™, the details of which are a closely guarded secret.

The KLEI Absolute®Harmony RCA plugs also have a couple of other proprietary changes (again hush hush), but they retain the same high melting point thermoplastic polymer housing assembly that snaps into place on an RCA socket.

The housing employs two grub screws and a small rubber collar to retain and secure the cable. Inside are the tag-shaped connections for the signal and earth for soldering and an anti-shorting shield to maximise the distance of the wires from each other, minimising inductive, capacitive and EMF effects.

Absolutely Fabulous

I have been impressed by the KLEI Pure® Harmony RCA plugs in the past but will I be able to detect any improvements with the KLEI Absolute®Harmony RCA plugs?

I make up a set of interconnects using the same wire as with the KLEI Pure®Harmony RCA plugs.

After running them in, I am greeted with the excellent imaging, bass control and dynamics that characterise the other KLEI Pure®Harmony RCA plugs.

I swap back to the KLEI Pure®Harmony RCA plugs and although to my ears they sound the same as the KLEI Absolute®Harmony RCA plugs in terms of describable metrics, I don’t experience the same level of enjoyment that I do with the KLEI Absolute®Harmony RCA plugs.

Listening to Beethoven’s Ninth Symphony, the final movement sounds more rousing with the KLEI Absolute®Harmony RCA plugs and the choral segments are a tad more exciting.

If you’re into making up your own interconnects, then the new KLEI Absolute®Harmony RCA plugs absolutely deserve to be placed at the end of your cables. NR
