I have had the purple outlet for 18 hrs running, which replaced a Black outlet.
Was impressed by the nice copper coloured contacts, quite certain it is and had very high expectations.
So far i can say it is nice, more naturalnsoynding. It is definately more mellow than the black outlet, less analytical and more toned down highs, copper contacts attributed to this effect.
I will let it burn for another few days, but undecided, i miss the more apperent details and clarity of the Black outlet and leaning to swap back the black.
My gut feel, is that ibprefer the Black oitlet as i have fined tuned the sound over these few years.
It seems the new offerings from SRbare more a lateral change.
I use All SR outlets from the original teslaplex, red, black, blue ,orange and now purple.
There is nonfurther noticeable upticks, just different presentations with new colours.
