Tier L · Twin Arms (mandate — one system, two front ends)
Two cartridge-and-arm front ends on one shared deck and core — one voiced for timing and drive, the other for warmth and scale — so the whole run of music has something built for it.
One certified system per brief. Costs appear only as signed percentages against each tier’s (unpublished) baseline; absolute prices are not shown.
One system, built once. A single deck, phono stage, amplifier and pair of loudspeakers are shared; two independent cartridge-and-arm front ends sit on top of them, each voiced for a different kind of listening. You choose between them by choosing an arm, not by rebuilding the system.
The shared core

| Integrated amplifier | Exposure 3510 |
| Loudspeakers | ProAc Tablette 10 Signature |
| Subwoofer | KEF KF92 |
| Whole-system cost vs tier baseline | +4.0% |
The two arms
Arm 1 · PRaT
For timing, drive and momentum.
| Cartridge | Linn Kendo MC |
|---|---|
| Tonearm | Origin Live Onyx Mk5 |
Arm 2 · Romantic
For warmth, body and orchestral scale.
| Cartridge | van den Hul The Frog |
|---|---|
| Tonearm | Origin Live Alliance Mk5 |
One phono stage with two inputs serves both arms — no second stage was needed. 2 decks at this tier can carry two arms at once. The two arms never share a cartridge or a tonearm: the second is built to be unlike the first, by construction rather than by preference.
How the money is shaped
How the budget is shaped here — each share is the portion of the whole build this brief aims at that position. A position marked free is left to find its own level. The two arms each carry their own cartridge-and-arm share.
| Position | Share of build |
|---|---|
| Cartridge (each arm) | 13.0% |
| Tonearm (each arm) | 3.1% |
| Turntable | 16.3% |
| Phono stage | 12.0% |
| Integrated amplifier | 16.9% |
| Loudspeakers | 22.4% |
Why there is a subwoofer
A subwoofer is fitted. Below this loudspeaker’s natural reach there is real musical content — organ pedal notes, synth bass, the lowest drum weight — and the coverage arithmetic says a dedicated bass cabinet genuinely extends the system rather than doubling what the loudspeaker already does.
