CCA NRA MINI-REVIEW
TONALITY: 7.6/10
TECHNICALITIES: 7.2/10
CONSTRUCTION:8/10
SOUND VALUE: 7/10
Disclaimer: I don't do this with joy...it is forced and uninspired review labor. CAA take my little nephew in hostage, if i don't do this review they will keep him for chain work in their NRA and ZEX factory.
TONALITY: Thick warm'ish W shape, balanced with slight mid bass emphasis and upper mids boost.
TIMBRE: Grainy, bright, neither natural or artificial but can feel like it's filter through a transistor radio some time.
SOUNDSTAGE: Quite wide and tall but with zero deepness to it.
IMAGING: Poor, hollow and hazy, compressed layering, lack of instrument space for proper separation.
RESOLUTION: Average to poor for the price, especially when it come to proper definition of instrument or micro-details.
BASS is the worst part of NRA to my ears, the slam is loose, tone is warm and timbre is grainy, this isn't clean bass at all and extension is not natural, while it doesnt intensely bleed on mids, their no proper separation neither. Transient-attack is slow. Definition is hollow. Kick drum and sub-bass easily mix togheter. Harmonic distortion is anothetr issue.
MIDS lack lower harmonic, so piano or male vocal can sound a bit thin or distant, female vocal in other hands are quite fowards in presence. Timbre is natural enough here, imaging isn't well articulated so everything feel stick togheter which can be a plus in term of cohesion but not in resolution. Slight sibilance can occur with female vocal but not in a problematic way, still it affect naturalness and make it sound a bit ''plastic''. Between lush and dry are the mids, neither too warm or bright, it's the kinda mids that isn't addictive or musical to my ears.
TREBLE might be the best aspect of the NRA, but in a half-done way....in fact, it feel like we listen to a prototype IEM not a fully achieve one. If we can find a bit of air, it's between mids and upper treble. Highs are the most snappy aspect of the sound as well as fastest in attack. It doesn't have decay, neither sparkle, and minimal brilliance to it. We can say it's dry, but in a EST way....similar to planar and piezo....but, man....perhaps it's my pair that have bad QC,but i can hear buzzing and sound artifact....anyway, percussions can sound quite good (crisp but thin), even when complex and varied in colors...that's when I can see EST potential and get excited.
COMPARISONS
VS KBEAR KB04 (1DD+1BA-22$)
Cleaner, clearer, brighter and more vividly balanced is the KB04.
Clarity and imaging is at another level here. Attack speed too.
BASS is tighter and punchier yet better separated, it's more textured and transparent too.
MIDS are crisper, cleaner, brighter, more centered and articulated, more transparent. Timbre is thinner, more textured but less natural. Female vocal are more intimate, less wide and upfront.
TREBLE is fuller and better balanced, it dig more sound info and is more emphasis. NRA feel it dig half-part of sound info.
All in all, tonality of the NRA is smoother and less cold than KB04 which is notably superior technically.
VS FINAL E1000 (1DD-30$)
Better balanced, smoother, fuller, lusher sounding. More warm-neutral. Tonality refinement is at another level here.
Clarity have greater amount of sound layers, more texture and feel unforced.
Soundstage is more holographic, bit less tall, bit deeper and feel more open.
Imaging is notably superior in instrument placement and layering even if it suffer from lack of air which is similar to NRA.
BASS is a bit flatter and more rolled off in sub bass, you have less rumble but less muddyness too. Tone is more realist. Speed is similar but control is better.
MIDS are fuller, lusher, wider, thicker. Both male and female vocal sound more natural and smooth. Layering is better articulated too.
TREBLE is more relaxed, less snappy but richer in tone nuance and texture. Thicker highs with more organic balance.
All in all, NRA is a piece of garbage compared to E1000. Its like Adele (or Agnes Obel) singing against a nobody using Auto-tune.
CONCLUSION
Sure, I can't say the NRA are plain bad for the price, the tuning hold up togheter and is well balanced as a whole, a sirupy thick whole. For those that doesn't know me, i can go overly grumpy when my expectation are let down and this is what happen with the EST tech in this...i was expecting something better than cheap BA or piezo which isn't the case. I don't see the point of talking about NRA and getting excited with its EST when **** **** was launch 5 years ago and offer a way more impressive and immersive sound with better technicalities but slightly less balanced tonality. KBear KB04, Tanchjim Tanya, Final E1000 or for 10$ more BQEYZ KC2 all offer a more impressive sound value than these overrated NRA. Do we need another ''jack of all trades, master of none''? If so, the NRA is there for you!

PS: thanks to Keephifi for the review sample. You can now tell CCA to release my nephew.

And I think kz/cca still doesn't have a sound engineer. They don't have a house sound or anything that signs the presence of an intention behind a certain tuning.
