The sonic result is extraordinary: a presentation of music that is simultaneously commanding and delicate, with a pitch-black noise floor, titanically controlled bass, and a midrange of exceptional purity.\u003c\/p\u003e\n\u003cp\u003eThese units have spent the majority of their working lives as the driving force behind a world-class reference system anchored by the Wilson Audio Chronosonic XVX loudspeakers with matching subwoofers — one of the most demanding and revealing speaker loads available — wired throughout with Transparent Reference and Opus cabling. No amplifier in this system was asked to work hard. Both units are in the same superb cosmetic and sonic condition you would expect from a climate-controlled, smoke-free and pet-free environment.\u003c\/p\u003e\n\u003cp\u003eOriginal crates are included, making shipping and future transport straightforward — a detail that matters enormously with amplifiers of this size and value. For the buyer who wants the best that D'Agostino builds in a monoblock configuration, and who wants it with meaningful provenance and complete packaging, this pair is exceptionally hard to improve upon.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCore Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100.267%;\" class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 32.1942%;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"width: 67.446%;\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003eMonoblock (sold as matched pair)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eOutput power\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e800 W @ 8 Ω · 1,600 W @ 4 Ω · 3,200 W @ 2 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eAmplifier class\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003ePure Class A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eTopology\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003eFully balanced, fully discrete, zero global feedback\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eGain\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e26 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eFrequency response\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e1.5 Hz – 100 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eDamping factor\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e\u0026gt;1,000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eInputs\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003eBalanced XLR · Single-ended RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eInput impedance\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e100 kΩ (balanced) · 50 kΩ (unbalanced)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003ePower consumption\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e~1,500 W idle (per chassis)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eDimensions (W × H × D)\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e19\" × 9.5\" × 21.25\" (483 × 241 × 540 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e~175 lb \/ 79.5 kg (per chassis)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 32.1942%;\"\u003eRetail price (new)\u003c\/td\u003e\n\u003ctd style=\"width: 67.446%;\"\u003e~$115,000 USD per pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails \u0026amp;
