Hi,Well, I’m coming back here to give some news, since I ended buying a 3TS762 because I had a discount on one, so I was able to try it.
Now I can speak about these two cables, so this could be useful for some of you.
Both of these cables - TCS31 and 3TS762 - share the sound signature of Furutech cables: very smooth midrange, some kind of a liquid sound. But unlike the 3TS20, they don’t have some highlight in the upper midrange or in the treble (the 3TS20 had a highlight in the treble only with low power gear, like dacs or headphone amps).
Both of them have more presence in the bottom than the 3TS20, more dynamic and deepness in the soundstage.
Their main difference is located in the midrange. The 3TS762 is a quite neutral cable (but very smooth with zero agressiveness, and a very thick sound), and the TCS31 is a mainly warm cable, which adds some colour to the sound (and has essentially the same amount of thicknes/smoothness).
According to your preference, you could prefer one or the other. The warmness of the TCS31 is extremely seductive. It has some kind of a nocturnal feeling, but you lose a bit of light in the upper-midrange and some intruments may sound a little less realistic than with the 3TS762.
The 3TS762 also seems to have a bit more bloom in the bass, while the TCS31 seems a bit more straight, defined in the bass and at the same time less thick (but not lean).
I ended using one or the other according to my humor, the amp I want to use, the headphone or speakers I want to use, etc.
Imposible to go wrong with either of them.
In the end, the 3TS762 sounds like the 3TS20 without its shortcomings, and it even works with low power devices (superb on my KGSSHV Carbon headphone amp, for example), like the TCS31, which makes the 3TS20 the least interesting Furutech cable (but it remains, by the way, a great cable).
The 3TS762 has a bigger soundstage, more dynamics and more bass slam than the 3TS20.
Any here try Oyaide Tunami V2 102 power cable?
Like I said, I had some of them. They sounded quite dry, on the lean side. Very detailed but lifeless, to me. I didn’t like them and sold them.
