Sound Analysis.

Blaze ($539, link)

Wire Structure:

• Custom Litz + X-Cross
• Nano Silver-Gold oil soaked with silk wrapping

Material:

• Gold plated 7N OCC Copper +
• Silver-Copper Alloy +
• 7N SC-OCC Copper

The cable is 4.4mm terminated and equipped with ConX 2.0 full set (2pin 0.78, mmcx, a2dc, IPX, Pentaconn ear).

While testing Blaze with various IEMs, I found its sound characteristics to contribute to the sound of these IEMs with (a sound description relative to IEMs under test):

• Keeping a wide round soundstage with an even expansion in all three directions and holographic imaging.
• Maintaining the black background.
• To my ears, this cable has more of a copper characteristic with enhanced deeper sub-bass rumble and well-controlled tighter mid-bass punch, clear detailed mids with some enhancement relative to detail retrieval, and airier sparkle in treble.  The sound enhancement is not overwhelming, but very balanced across the spectrum.  The cable “cleans” up the mids and tastefully enhances bass and treble.

Thanos ($639, link)

Wire Structure:

• Custom Litz + X-Cross
• Nano Silver-Gold oil-soaked with silk wrapping

Material:

• Gold plated 4N Silver +
• Palladium plated 4N Silver +
• 7N SC-OCC Copper

The cable is 4.4mm terminated and equipped with ConX 2.0 full set (2pin 0.78, mmcx, a2dc, IPX, Pentaconn ear).

While testing Thanos with various IEMs, I found its sound characteristics to contribute to the sound of these IEMs with (a sound description relative to IEMs under test):

• Maintaining the average width soundstage with more depth/height, which projects the sound placement slightly more in front of you.
• Maintaining the black background.
• To my ears, this cable has more of a neutral-ish characteristic.  It does enhance the retrieval of details, tightens the sound a bit, but overall, it doesn’t boost the bass or adds body to the mids or makes the treble brighter.  Considering its materials, I would expect the sound to be brighter.  It is a little more revealing, helping with retrieval of details, but it doesn’t make it brighter, maintaining the neutral coloring.

Ultron ($1,019, link)

Wire Structure:

• Custom Litz + X-Cross
• Nano Silver-Gold oil-soaked with silk wrapping

Material:

• Gold plated 4N Silver +
• Palladium plated 4N Silver +
• 4N Pure Silver +
• 7N SC-OCC Copper

The cable is 4.4mm terminated and equipped with ConX 2.0 full set (2pin 0.78, mmcx, a2dc, IPX, Pentaconn ear).

While testing Ultron with various IEMs, I found its sound characteristics to contribute to the sound of these IEMs with (a sound description relative to IEMs under test):

• Keeping a wide round soundstage with an even expansion in all three directions and holographic imaging.
• Maintaining the black background.
• To my ears, the revealing factor of Venom (discussed next) is taken down one notch with a little more polite sub-bass rumble and slightly more relaxed mid-bass punch, mids are a touch smoother, more natural, still very detailed, clean and clear.  Treble has a natural crunch and a bit more airiness bringing a nice layering and separation to the sound.  While Venom might be good for darker tuned IEMs, Ultron is more universal to clean up the sound with more revealing natural details.

Venom ($1,289, link)

Wire structure:

• Signature series with positive and negative conductors
• custom litz + X-Cross + Air Tube Structure

Material:

• Positive:
  • Gold-Plated Silver-Gold Alloy
  • Palladium-Plated Silver-Gold Alloy
  • Ag-Au-Pt Alloy
  • 7N SC-OCC Copper
• Negative:
  • Palladium-Plated 5N OCC Silver
  • 5N OCC Silver

The cable is 4.4mm terminated and equipped with ConX 2.0 full set (2pin 0.78, mmcx, a2dc, IPX, Pentaconn ear).

While testing Venom with various IEMs, I found its sound characteristics to contribute to the sound of these IEMs with (a sound description relative to IEMs under test):

• Keeping a wide soundstage opening with even more depth and taller height.
• Maintaining the black background.
• To my ears, this cable has a more revealing sound enhancement with deeper and “cleaner” sub-bass rumble, tighter faster mid-bass, a bit leaner lower mids and more revealing upper mids, and extra air/crunch in treble.  This cable brings out more details without making the sound brighter but rather making it more revealing and less colored.  Very good pair-up with warmer tuned IEMs.

Conclusion.

As I always mention in my cable reviews, the wire doesn’t have a sound.  Everything will depend on the pair-up synergy since the essence of the cable is to finetune the baseline signature of your IEMs.  There is no magic “EQ” silver bullet or fairy dust behind wires of the cable.  If you are unhappy with the sound of your IEMs, get another pair of monitors with a different sound signature because a cable should not make a night and day difference.  And I’m saying this as a true cable believer.  Also, the higher in price you go, the more diminishing returns you should expect, especially when it comes to cables.

I know that some look into the cables from cosmetic/aesthetic perspective, and there is no denial about these having quite an eye-candy design along with a practical full set of ConX connectors to use with any of your 2pin, mmcx, or P-ear IEMs.  Also, considering the original design, manufacturing, and exotic wire materials, I find the pricing reasonable as well.  But it is not just about the looks, but what they contribute to the sound.  Based on the sound characteristics of these Flash Acoustics cables in my testing with various IEMs, they should finetune the sound of your monitors, and I hope this review will be helpful for my readers to decide if these should be considered for their next cable upgrade.
