Great upgrade cable

I was looking for slightly brighter sounding cable for my 64 Audio custom IEM, and this is the perfect one. Great feels, great design, amazing build. It’s already my 3 cable from Null Audio, I’ve been extremely happy

Superb!

I listen to HD jazz & classical music using a Luxury & Precision P6 Pro DAP with Cosmic Ears CE6P IEMs. I purchased the AAW Thera MKII UP-OCC Cryo Silver IEM cable as an upgrade of a cable from a major manufacturer that costs about half the price of the AAW Thera. I’ve been listening for about 25 hours so the cable is most likely not burnt in fully.

I’m extremely pleased with my purchase. As other reviewers have pointed out these cables are a stunning work of art, manufactured to the highest standards. I opted for the herringbone 8 braided configuration and although they are heavier than a conventional cable I’ve found them to be perfectly comfortable listening to music when seated.

The sound is supremely better than my original cables. The sound stage is wide and holographic with excellent separation of individual instruments in pieces ranging from orchestral music to small jazz groups. In a cacophony of orchestral percussion and brass a single wind instrument resolves with absolute precision and detail. I suspected that the Null audio cable would release greater depth, clarity, precision and detail from my music collection given the quality of the DAP and IEMs and I am not disappointed. They are superb to the extent that I have to listen to my entire music collection again and am constantly astonished to hear detail and nuances that I had not been aware of before. Thank you Null Audio.

I use the dap with nw-wm1a and iem with ue live. Anyway, the localization and separation of the sound is great.

AAW Thera MKII - Amazing Build Quality, Incredible Sound

I’ve never believed that cables make any difference in sound. I have several cables in the past, all of which different quality in copper and to me, it sounded the same. I wanted to try whether or not silver makes any difference. I ended up here at Null Audio, ordered the Thera MKII and added the herringbone upgrade. As soon as it came in, I connected it straight to my Empire Ears Legend EVO IEM. For those that don’t know about this IEM, it is a hybrid configuration with a Bone Conduction driver, two dynamic drivers and 5 balanced armatures. This IEM is a BASS CANNON, which slightly recesses the treble. I love the performance but always wished that there was a bit more bite to the treble frequencies. I’ve noticed with this cable, the soundstage is much wider now along with adding a bit of sparkle on the top end. Just enough to make this my endgame. It also smooths out the bass which for some songs can be too much. The build quality and materials of this cable rivals cables that cost twice to three times more than it. I’m very happy that I came across Null Audio and purchased this cable. You will not regret your purchase here. If you’re looking for a little more sparkle in your top end and a wider soundstage, please consider purchasing the AAW Thera. It is a bit heavier due to the herringbone upgrade, so if you want a lighter cable, don’t opt for that upgrade.

Great quality...again!

I have purchased the Lune before and loved it, this time I decided to get the Thera MKII as an upgrade, and ended up very satisfied again.
The cable seems thicker campared to Lune even in 4 wire buit still soft enough, and the sound is excellent.
