Forgot to mention Glasshouse stepped attenuators as they are also better and can get very expensive. Hifi Collective sells them. Both of these are better than the K based on my research over the past year.
I can tell you these top flight stepped attenuators make a big difference in preamps. If the current Attenuator is an Alps or some other pot, then this upgrade will be a revelation.
I would also build it as a shunt type of stepped Attenuator.
