Received the cable on Monday... only get to test it today in the car through aux in... with my Rockbox-ed sansa clip+
The difference is... well... i can say really huge and i love it especially on the vocals...
Vocals...
They are much much more "centered and weighted but with a sense of crispyness." Previously it straines a little to figure out what the singer is wording out, but with this cable, i would wish for the vocals to be mastered or mixed a little bit lower in the studios for cetain songs! Jokes aside, much improvement overall to the vocals.
Bass...
Bass wise slight improvement, more presence or foward-ness to the really low freqencies (around 25-45hz i think) Try listening Kenny G's - That Somebody Was You with a good pair of speakers or headphones, those really low bass notes became much more forward.
Mid...
Apart from the astonishing vocal performance, other mid-centric instruments seem more prominent. Especially the drums, the impact of the snare and toms sounds... well, more impactful... Try Paramore's - That's What You Get or Misery Business... those drum attacks have more impact and tautness making the music more lively... Again, it's that "full sound, but with a sense of crispyness" When i mean full... it's supposed to mean fat (eg prominent mid bass) but there is just something crispy from this cable that makes it very enjoyable
Treble...
More detailed, crispy, better seperation... Eg in Metallica's - The Thing That Should Not Be, the cymbals rolls on certain parts were panned from left to right... but it was more centered previously, now the left to right "surround" effect is more prominent... cant say much on the treble... the engine makes a certain soft hissing inside the cabin under throttle, which distracted a little...
Stereo Stage...
Will update later after testing with some 2.1 systems... in car u're either sitting on the left or right and it's unfair to judge stereo unless u're at the center
really love this cable... thanks ssyycc for such a great product. mayb in future will get a minijack to rca for straight input into rca line in of the amp =p let me get bored of this 1st!
ps...before this i was using a cheap RM5 cable to connect... no brand, nothing, even the left/right cables are not in seperate lines, no shielding... so mayb that's why such big improvment

Wow, this is one of the best review I got later for sure will copy this in my first post here. Thanks a lot for the compliment. Happy new year to all my customer and all Lyn forumer.
