We didn't.

One hundred watts per channel into 8 ohms, doubling into 4, is ample for efficient and moderately demanding loudspeakers — bookshelf monitors, stand-mounts, and full-sized floorstanders — in small to medium rooms. It is the ideal first step into the Signature Series, and for a great many listeners with sensible speakers in a dedicated space, it will prove to be the last amplifier you need.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-brief__body rte\"\u003e\n\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pmg-brief__body rte\"\u003e\n\u003ch2 class=\"pmg-tech__heading\"\u003eClass A Purity\u003c\/h2\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eMost of what we call \"high-end\" amplification is, in truth, Class AB: a small region of Class A operation at low power, and then a transition — a handoff between transistors — as the music grows louder. That transition is not free. At the crossover point, distortion artifacts appear, and the music briefly crosses a discontinuity it was never meant to encounter. Class A operation eliminates that handoff entirely. Every transistor conducts through the whole waveform; nothing ever switches off.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eThe reason Class A is rare is cost. A Class A stage runs hot and consumes power continuously, even at idle, so most designs offer only a sliver of it. It is rare for a high-end amplifier to deliver even a single watt of true Class A before it slides into AB — and a great many that advertise \"Class A\" give the listener only a fraction of one.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe S200 dedicates 10 watts of pure Class A bias to each channel. In real-world listening — efficient speakers, sensible rooms, the levels at which music is actually enjoyed — that 10-watt window covers roughly 20% of typical listening, and nearly all of the low-level detail where the ear listens hardest. The S200 is the most accessible amplifier in the PMG Signature Series, but its commitment to genuine Class A is not an accessible-tier commitment. It is the same engineering conviction that runs through every Signature amplifier, scaled to the system it was built to serve.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003ch2 class=\"pmg-tech__heading\"\u003eActive Power Supply\u003c\/h2\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eThere is a reason the most uncompromising amplifiers have always been monoblocks: one channel, one chassis, one power supply, and therefore nothing for that channel to fight with. A stereo amplifier gives up that isolation by definition — its two channels share a single power supply, and a demand from one can disturb the other. When a passive supply sags under a sudden current draw, both channels sag with it, and the stereo image pays the price.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe S200 is a stereo amplifier that refuses to pay that high price, and the reason is the supply at its heart. Its two channels share a state-of-the-art active power supply — but an active supply does not behave like a passive one. It delivers far cleaner power and far greater current on demand, and it holds its output stiffer than any traditional supply. A transient on one channel drags the supply down only minimally, so it hardly impacts the other. The sharing becomes, in practical terms, invisible.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eWhat the supply begins, Bob Stadtherr's engineering completes. Decades of experience went into the S200's internal layout — the grounding scheme, the placement of every stage, the mechanical structure — all arranged so the two channels stay electrically and magnetically apart. The result is a 100-watt-per-channel stereo amplifier, doubling cleanly into 4 ohms, whose channel separation approaches that of a true monoblock. The most accessible amplifier in the Signature Series gives up far less to its single-chassis form than its price suggests.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003ch2 class=\"pmg-tech__heading\"\u003eOutput Stage\u003c\/h2\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eThe final and most consequential choice in an amplifier's design is how much negative feedback to apply around its output stage. Feedback is a correction loop: it watches the output, compares it to the input, and cancels the difference. In large amounts it can push measured distortion on a steady test tone close to zero — an impressive specification. But music is not a steady tone. It is a continuous storm of transients, and a heavy feedback loop, forever reacting, is always a step behind it. The amplifier ends up chasing the music instead of passing it through cleanly, and the listener hears the difference as a loss of life and immediacy.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe S200 is designed on the same conviction as every amplifier above it in the Signature Series: keep overall feedback strikingly low. The output stage is made linear by design, not by correction, so distortion stays uniformly low across the entire audible band without a heavy loop scrubbing away after it. Bandwidth extends well past 500 kHz, and transients arrive whole.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe reward is the quality the entire Signature Series is named for: the amplifier disappears. At the S200's most accessible point of entry, nothing about that disappearing act has been diluted — the same musical priorities, the same engineering conviction, the same refusal to let the electronics be heard. Only the price of admission has changed.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e100 watts into 8Ω per channel, doubling to 200 watts into 4Ω per channel\u003c\/li\u003e\n\u003cli\u003e10W Class A bias per channel\u003c\/li\u003e\n\u003cli\u003eSlew Rate \u0026gt;200V\/uS\u003c\/li\u003e\n\u003cli\u003eBandwidth exceeding 500 kHz\u003c\/li\u003e\n\u003cli\u003eStrikingly low overall feedback architecture\u003c\/li\u003e\n\u003cli\u003eState-of-the-art active power supply\u003c\/li\u003e\n\u003cli\u003eDesigned by Darren Myers\u003c\/li\u003e\n\u003cli\u003eEngineered by Bob Stadtherr\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"PS Audio","offers":[{"title":"Silver","offer_id":43726427291711,"sku":null,"price":12490.0,"currency_code":"AUD","in_stock":true},{"title":"Black","offer_id":43726427324479,"sku":null,"price":12490.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0855\/5776\/files\/PMGS200StereoSignaturePowerAmplifier_2.png?v=1786483704","url":"https:\/\/www.lenc.com.au\/products\/pmg-s200-stereo-signature-power-amplifier","provider":"Living Entertainment","version":"1.0","type":"link"}
