Don’t know if Zu has replaced the Mother, in their lineup, but: I found it an excellent PC and VERY flexible (critical, given my present component/cable configuration).
Currently: they supply my BAT VK-D5 CDP, phono pre, TacT 2.2X, Cary SLM 100 main amps and I can’t imagine ever needing further upgrade.
All my other PCs and interconnects are either Synergistic Research or Kimber Kable Selects, so: it’s not like I’m a strict brand-fan.
They can be hard to find, in the used market, but: well worth the effort.

Happy listening!
