Nagra AMP II-S — Evidence Profile
L1 evidence profile · official and regional-source follow-up · checked 22 October 2026.
Decision first
Keep AMP II-S at L1. A manufacturer-listed regional distributor now has an exact-model page, but that page contradicts itself about channel configuration and power supply. Obtain a corrected exact-model specification and operating manual before committing to a system or purchase.
What the authorization check establishes
Nagra’s official high-end network lists AudioNatali for Italy, Gaudios for Germany/Austria, Absolute Sounds for the UK, Intrada for Poland and the China-region representative linked to Hyperaudio. This establishes the listed regional channel; it does not validate every specification, stock label or delivery promise on its website.
Exact-model source conflict — unresolved
AudioNatali page 1717 is titled AMP II-S. Its header describes a pair of monobloc power amplifiers with a 2 kVA supply; its description instead calls the unit a stereo power amplifier with an 800 VA transformer, rated 120 W RMS per channel into 8Ω, with the first 10 W in Class A. Both statements are retained as conflicting source claims. Neither configuration is promoted to a settled product specification.
Wittmann’s AMP II-S retail page also describes the stereo/800 VA/120 W at 8Ω configuration. Its retailer statement does not resolve the distributor page’s internal discrepancy, and this review did not independently establish Wittmann’s authorization through the reviewed manufacturer/distributor network. Repeated copy is not an independent measurement or a manufacturer correction.
This is a documentation discrepancy, not evidence of a hardware defect. We have not created or closed a Product Issue from it. Marketing descriptions of sound are not accepted as SPL listening evidence.
Manual and operating conditions still missing
No verified exact AMP II-S owner manual was obtained. AudioNatali’s manual area and Absolute Sounds’ download search lead to sign-in; no new account or access permission was created. Gaudios’ reviewed public Nagra catalogue/download entries and Intrada’s Classic/HD material did not supply an accepted AMP II-S operating document. PREAMP II-S and Classic AMP documents remain different-model exclusions.
Before installation, confirm exact inputs, preamp sensitivity/gain, speaker-load limits, any mono/bridge mode, mains and ventilation in the correct manual. Do not infer these from the old amplifier or from the conflicted listing. The 21 October media report date is not assigned as a first official release date; regional price, stock and actual delivery remain unverified.
Who should wait; what we tested
This profile is useful for tracking the model and preparing precise questions for the listed regional support channel. Wait if your installation depends on accepted load, gain, channel-mode or delivery facts today. Keep a working amplifier until an identified requirement is supported by corrected documentation. Compare alternatives by required role and their own accepted conditions; no audible upgrade has been established.
Source and documentation review only. SPL has not installed, measured or auditioned this model, verified a repair, scored its performance or certified a recommendation.
Reassess when a corrected exact-model manufacturer/distributor document resolves the discrepancy and supplies operating conditions. L1 remains an evidence-coverage label. The same standard applies to represented and unrepresented brands.
