Why 89?
A weighted aggregate of four category scores. Reasoning is editorial — physics-grounded engine in development.
Cambridge Audio CXA81 Mk II's 80W into 8Ω, 120W into 4Ω is more than enough for the Spendor A2.2's 4Ω-friendly load. Class A/B with documented stable behaviour into the Spendor's mid-impedance dip.
Rega Planar 2 + Rega Fono MM MK5 — pairing that's well-documented across audiophile forums for clean MM cartridge output. External phono stage outperforms the CXA81's built-in line input by avoiding the integrated's internal noise floor on tiny cartridge signals.
5.5 × 3.8 m suits the Spendor A2.2's small floorstanding profile. Their British-room design philosophy expects rooms in this size range. Listening distance of 2.8 m keeps the listener in the integrated direct/reflected field the speaker was tuned for.
Spendor A2.2 is a documented neutral-warm voicing. CXA81 Mk II's measured-flat preamp section preserves the speaker's character. Vinyl source adds expected mild euphonic colour without dominating the presentation.
