Hi,
I put together a system in 2001 with Copland CSA28 hybrid amp, Micromega CD player, B&W CDM1SE monitors on stands, and Transparent magic cables.
It has done me well for 23 years, with two changes of triode valves, and a move from CD player to Bluesound node stream Qobuz into Beresford Caiman DAC.
I built an ACI Titan 250W sub because of its renowned ability for the twin 12dB filters to allow it to sit seamlessly under the monitors and extend their range a couple of octaves, which it does beautifully.
I came here chasing schematics for the sub because a power fluctuation has blown something. Hopefully its just the power supply.
All the best
