I would also consider swaps:

Any M gear
Other hifi stuff (not speakers, I’m a DSP kinda guy)
Astronomy gear
Unwanted or disused wives (if in reasonable condition).

Cheers,
Jason.

Lounge: DSP5200SL (L-R), DSW, 218, Michell Tecnodec, G98DH, tape deck.

Shed: DSP3100HC mains with twin analogue subs, 568, MS200. This sounds waay better than it should.

Storage: Way too much Meridian stuff, but I'm culling.
