In all seriousness, these are excellent cables.
1] All soldered contacts are perfect, cable trimming is perfect.
2] Heavy terminators that easily conform to varying RCA socket widths
3] No heat shrink tubing used OR adhesives of any kind
4] A flexible outer shield is used the entire length of the cable that protects against abrasions and acts as a strain relief
5] 100% hand tailored and thoroughly inspected for build quality & performance
As stated in the product description, they are designed to work well out of range of audio frequencies. Internal losses within the AF band are virtually non-existent. I never liked the idea of 'hearing' a cable. There are other things to contend with, so why should a cable be a sonic contributer?
The sound of "absence" in itself is what's important. LH-1's will not attenuate anything at all, nor boost anything. Relative to your present cables, there could be a clear improvement- but it is due to non-interference.
