Every one has been a step toward sonic perfection — each teaching us something the last could not: about power supplies, about feedback, about the quiet ways an amplifier can color the music it carries. The M800 is where that road arrives.\u003cbr\u003eEight hundred watts into 4 ohms, doubling cleanly down from 400 into 8 — decisive, effortless, never strained.\u003cbr\u003eBut power was never the hard part. Speed, evenness, and restraint were. The M800 is the first amplifier we've built to hold all three at once.\u003cbr\u003eIts slew rate exceeds 200 volts per microsecond. Hand it a 10 kHz square wave — the cruelest signal in audio — and it returns vertical edges and flat tops, no overshoot, no ringing. In fifty years we have never seen one this perfect. Distortion stays flat and low across the entire audible band, never trading one frequency for another. And it does all of this with strikingly low overall feedback — no heavy correction, just the music. Remarkable.\u003cbr\u003eDesigned by Darren Myers. Engineered by Bob Stadtherr.

Where a conventional amplifier leans on a heavy passive transformer, the M800 is built around a state-of-the-art active power supply — a design that delivers current with a speed and stability no transformer-based supply can match. Around it sits Darren Myers' low-feedback current-based topology, chosen deliberately: the less an amplifier has to correct itself, the more honestly it passes the signal through. Every M800 is assembled and tested by hand in Boulder, Colorado, and brought into production by Bob Stadtherr — whose work ensures the amplifier you receive measures and sounds exactly like the one Darren designed.\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-brief__title\"\u003eApplication\u003c\/h2\u003e\n\u003cdiv class=\"pmg-brief__body rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eEach M800 is a monoblock — one chassis, one channel — sold as a pair for stereo. With 800 watts into 4 ohms and the current to double down without strain, a pair will drive virtually any loudspeaker made, from sensitive horns and electrostatics to the most demanding low-impedance reference designs. There is no speaker too difficult and no room too large. If you own loudspeakers that have humbled other amplifiers, the M800 is the pairing that ends the search.\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\"\u003eClass A is the most linear way an amplifier can operate — and the most expensive. In a Class A output stage, every transistor conducts through the entire musical waveform and never switches off. There is no crossover point, no moment where one device hands off to another, no discontinuity for the music to stumble across. It is, simply, the purest mode of amplification known.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eIt is also brutally inefficient. A Class A stage runs hot and draws power continuously, even in silence, because its transistors are always fully active. That cost is why true Class A is so rare. It is rare for a high-end amplifier to deliver even a single watt of genuine, pure Class A — most designs that advertise the term operate in it for only a fraction of a watt before sliding into Class AB.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe M800 carries 50 watts of pure Class A bias. Fifty. Not a fraction of a watt, but fifty full watts before the output stage ever leaves its most linear region. For 99% of normal listening — and nearly all music lives well within that window — the M800 never crosses a notch, never sees a discontinuity, never asks its circuitry to correct an artifact it should not have created. What you hear is the natural texture of the recording: the body of a cello, the air around a voice, the decay of a struck cymbal, all intact. This is what Class A was always supposed to sound like. The M800 simply commits to it.\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\"\u003ePower is The Key\u003c\/h2\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eA power amplifier is, fundamentally, an interface between a reservoir of energy and the loudspeaker. The character of that reservoir — how cleanly it stores energy, how instantly it can deliver it, how silent it is at rest — determines more about how an amplifier sounds than any other single design choice. For half a century, the high-end audio industry has approached this with passive supplies: large linear transformers feeding banks of electrolytic capacitors. The approach works. It also imposes real limitations. The transformer is the slowest element in the amplifier's signal path. The capacitors store charge but cannot return it without ripple. The rectifier introduces switching noise every time it transitions. And the entire arrangement is sized for a peak demand it will almost never actually see.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe M800 is built on a state-of-the-art active power supply that delivers performance benefits no traditional transformer-based passive supply can match. Instant transient response with no rectifier-induced noise. A vanishingly low residual noise floor. Total grip on the speaker at any output level. Full continuous output without sag. The active supply is the M800's foundation — silent, fast, and capable of delivering everything the output stage asks for the moment it asks for it.\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\"\u003eThe PMG disappears into the Music\u003c\/h2\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eNegative feedback is the most powerful tool an amplifier designer has — and the most easily abused. Applied in large amounts, it can drive measured distortion on a steady-state test tone almost to zero. It looks spectacular on a spec sheet. But feedback works by continuously comparing the output to the input and correcting the difference, and that correction is never quite instantaneous. With music — which is nothing but transients, never a steady tone — heavy feedback always arrives a fraction late. The amplifier spends its life chasing the signal rather than following it. Transients lose their edge. Immediacy fades. The performance begins to feel like a recording of a performance.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv class=\"pmg-tech__text rte\"\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e\u003cbr\u003eThe M800 is built on the opposite philosophy: strikingly low overall feedback. Because its output stage is already extraordinarily linear on its own — running deep in pure Class A, where correction is barely needed — the M800 does not have to lean on a heavy feedback loop to clean up after itself. Distortion stays uniformly low across the entire audible band not by aggressive correction, but because there was little to correct in the first place.\u003cbr\u003eWhat this produces is the M800's defining quality, and the hardest to put into words: it disappears. The electronics stop announcing themselves. The speakers and the source seem to dissolve, and what remains is the performance — present, immediate, and whole. Eight hundred watts of authority, delivered with the openness of a far smaller amplifier. The M800 gives you both.\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\u003e400 watts into 8Ω, doubling to 800 watts into 4Ω\u003c\/li\u003e\n\u003cli\u003e50W Class A bias — 99% of typical listening in pure Class A\u003c\/li\u003e\n\u003cli\u003eSlew Rate \u0026gt;200V\/uS\u003c\/li\u003e\n\u003cli\u003eBandwidth exceeding 500 kHz\u003c\/li\u003e\n\u003cli\u003eFlat distortion across the audible band with strikingly low overall feedback\u003c\/li\u003e\n\u003cli\u003eState-of-the-art active power supply\u003c\/li\u003e\n\u003cli\u003eBalanced (XLR) and single-ended (RCA) inputs\u003c\/li\u003e\n\u003cli\u003eAvailable in Silver or Black\u003c\/li\u003e\n\u003cli\u003eHand-built in Boulder, Colorado\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\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":43709273669695,"sku":null,"price":45990.0,"currency_code":"AUD","in_stock":true},{"title":"Black","offer_id":43709273636927,"sku":null,"price":45990.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0855\/5776\/files\/PMGM800MonoblockSignaturePowerAmplifier.png?v=1786449826","url":"https:\/\/www.lenc.com.au\/products\/pmg-m800-monoblock-signature-power-amplifier","provider":"Living Entertainment","version":"1.0","type":"link"}
