IEM Comparisons
I’ve used a Luxury & Precision P6 Pro in hi-gain mode with an assortment of IEMs to test the ASOS+X.
Here’s the Tidal playlist I use to evaluate audio gear.
Tansio Mirai FEAT – 2xDD 2xBA (USD $239)
ASOS+X changes the FEATs substantially. The most immediately noticeable change is bass which goes way deeper and is far more emphasised than on the stock cable, with a lot more midbass in particular.
With that comes improved note weight, and even the lower midrange feels more prominent so the tonality is warmer, and everything sounds a lot meatier.
Staging is wider and slightly deeper, and detail through the midrange feels more effortless, whereas the stock cable feels brighter perhaps due to less emphasis on the lower frequencies.
ISN Neo5 – 1xDD 4xBA (USD $289)
In this awesome pairing the ASOS+X seems to coax the Neo5 midrange forward, to correct its’ natural v-shape to some extent.
I always thought the Neo5 stock cable had very impress sub bass output, but ASOS+X really deepens Neo5 bass substantially and makes it feel much more bass-oriented with better note weight.
The stage is wider, resolution is more effortless and tonality is warmer, making the stock cable feel brighter but also shaky & thin by comparison.
ISN H60 – 2xDD 4xBA (USD $349)
Compared with the stock copper cable ASOS+X brightens the H60s substantially and creates a much wider, deeper stage. Dynamics improve and resolution improves across all frequencies.
The tonality shifts upwards to accentuate the higher frequencies which exaggerates the H60s’ V-shape further, particularly as bass goes deeper with more rumble.
Everything feels grander with larger instruments, but I do prefer the warmer tonality of the stock cable.
Penon Quattro – 4xDD (USD $399)
I’m surprised how much further forward ASOS+X pushes the Quattro midrange, and dynamics are far more impressive.
The stage is slightly wider, the background feels slightly cleaner with better separation and bass feels a bit more powerful.
However ASOS+X brightens the Quattros and shifts them closer to a v-shape tonality, whereas I much prefer the smoother, more laidback presentation of the stock cable.
Tansio Mirai X – 2xDD 4xBA 1xPR (USD $399)
ASOS+X creates an even more bass dominant presentation with greater rumble and overall reverberation of low frequencies.
The soundstage also deepens, note weight improves and imaging feels a little sharper. Tonality seems a little brighter overall, and the overall presentation feels slightly scaled up with more gravitas.
Penon Turbo – 6xBA (USD $549)
In this terrific pairing ASOS+X makes the Turbos sound noticeably louder at the same volume level, with a substantially wider soundstage that’s also deeper.
Bass is greatly improved with more impact & heft, so the Turbos’ BA bass slams almost as hard as a DD.
Dynamics are also much improved, overall tonality is a little brighter which I feel benefits the Turbos given they’re naturally quite dark, an the result is a much more engaging overall sound.
