ZSTYX speaker cables are hard to hear
making them ideal for very transparent
sounding tube amplifiers. They are
recommended when focus, sound-stage and
transparency are a priority and you don't
want to give up bass slam to get it.
I found this wire at a ham fest in the
1990's when I was a sincere but broke
audiophile... it was military grade
silver-Teflon microwave transmission tower
cable. Something just told me it would be
better than anything I could afford so I
I had no idea how good it actually was until
we started comparing it to 4 figure $$
big-name cables... it was a real education
because of the huge gap in transparency we
heard on virtually every comparison.
This continued for years and when Decware
went online in 1996 there were countless
customers who brought their cables in to
compare. We learned that the more a
speaker cable costs, the more likely it is
to do some esoteric filtering which helps
offset the dryness and top end grain common
in so much solid state gear.
These have been my personal
reference cables since 1996 and I continue
to use them today. Each set is made to the
same mil spec number as my originals.
ZSTYX are actually separate conductors
wrapped in black Teflon making several

Running them either spaced apart, taped
together or twisted together can each have a
different audible effect in some systems.
When possible we usually run them spaced
apart and while the emission is highest, the
magnetic coupling between conductors is
- Conductors: Silver-plated copper with
40 microinches minimum coating thickness
per ASTM B-298.
- Insulation: Extruded PTFE, nominal
wall thickness .015 (0.4mm).
- Temperature Range: -55C to +200C
- Insul. Flaw Test (Spark Test): 5,700
volts rms @ 3.0 kHz..
- Min. Insul. Resist.: Meets calculated
- Heat Resistance: +290C for 96 hours.
- Voltage Rating: 1,000 Volts rms.
- This heavy-wall wire, rated at 1,000
volts rms or 3,000 volts DC, saves both
size and weight compared with many other
insulated wires of the same rating.
- Suitable for high-frequency use at
elevated temperatures in
high-reliability programs where
electrical and thermal stability are
