I did a quick a/b yesterday with a 308, s022n, dps-4, and Matrix on my Melody AN-845 integrated. Then did one on my Lampi Atlantic Plus dac with the 308, dsp-4, and s022n. On the 308, s022n, and dsp-4 have the same rhodium carbon fiber plugs that I think Mike at Tweek Geek uses as a cost effective option to the Furutech FI-50’s and on the s022n and dsp-4 I grounded the shield only on the AC plug end and have put Furutech nano liquid on the contact wires on all cables, except the Matrix of course. Now it would be much better to let each cable sit in the system for several days and then switch but I know my aural memory would not be so good for the previous cable, I guess I could take notes but I’m not interested in going that far...
On both the amp and dac I much preferred the dsp-4 to the 308. Much more natural and closer to the Matrix cable while the 308 to me seems just a little more digital sounding by comparison and can see if one has a warmer sounding system it would fit nicely. The s022n to me kinda falls in between these two and for the price of diy is a great option. Wherever I put the s022n I like it and it’s been one of my favorite cables as but I do think the dps-4 is better but for a lot more money.
The Matrix takes everything on the dsp-4 to another level with a lower noise floor and a notch better in realism. I could probably live with the dsp-4 but after hearing the Matrix now I can’t go back. Just me and my ears in my system so all this could be quite different for someone else. These are all great cables and feel it’s just a matter of fit for ones taste and system.
I do have a Black Mamba V2 on the way to compare later on.
