The Ultra replaced a Raspberry Pi running Volumio, a USB Atom DAC from JDS Labs, and a Bluetooth receiver, and, after some debate, even the Musical Fidelity Nu Vista pre-amp (slightly better phono stage but otherwise audibly very much the same).
The Volumio etc in turn replaced an older Squeeze based system, and the CD player itself went years ago.
So that just leaves the Musical Fidelity NuVista 300 power amp (notional 300W @ 8 ohm, but capable of nearly 1,200W when impedance dips to 2 ohms) driving a pair of Bowers and Wilkins 803 - that combo has stood me in good stead for 25 years and I think they're only just getting broken in now.
Wife very much likes the simpler setup, and I've hooked a Mini to the hifi in the kitchen diner so we can now have properly synchronised whole house playback for when we throw open the patio doors and have a BBQ get together.
Just thinking now about getting a Sound as a bedside speaker for the wife, if only so I can turn it off without getting out of bed when she forgets to set the sleep timer on the radio we use now, or just feeding another Mini into an old Heny Kloss Model One radio we've had for years
