Two-piece designs like this are among our favorites, as they typically offer an exceptionally low noise floor while isolating the audio circuitry from power supply interference.\u003cbr\u003e\u003cbr\u003eThe two chassis are connected via an aviation-grade umbilical connector—seriously robust engineering.\u003cbr\u003e\u003cbr\u003eAs with all Pass Labs products, the XP-22 exhibits exceptional fit and finish that few manufacturers can match. The brushed aluminum faceplate and chamfered edges look fantastic, and even the remote control is a standout.\u003cbr\u003e\u003cbr\u003eInputs include three pairs of RCA jacks, two pairs of XLR inputs, and a tape loop—something often missing on modern preamplifiers.\u003cbr\u003e\u003cbr\u003eThis unit includes its original box, manual, umbilical cord, and remote, making it one of the most complete and well-presented XP-22s available. \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSkyFi Cosmetic Notes:\u003c\/b\u003e\u003cbr\u003eThis set is near new cosmetically, only showing the tinyest of blemishes on the top covers on close inspection. Overall, Fantastic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrom Pass Labs:\u003c\/strong\u003e\u003cbr\u003eThe new design uses double-shielded low noise toroidal transformers in external supply\u003cbr\u003e\u003cbr\u003eThe new design uses double-shielded low noise toroidal transformers in an external supply connected via aviation-grade circular connectors using silver over oxygen-free copper. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics.\u003cbr\u003e\u003cbr\u003eThe gain circuitry continues to use our favorite transistors from Toshiba but has a larger, higher biased, output stage like the Xs Preamp, and includes auto bias.\u003cbr\u003e\u003cbr\u003eThe larger output stage makes longer, and multiple cable runs easier to drive and gives us the advantage of simplifying our single-ended output circuitry while increasing performance.\u003cbr\u003e\u003cbr\u003eThe volume control is a single stage instead of two stages and has more range; it is quieter and more accurate. This is the same volume control as used in the XP-30.\u003cbr\u003e\u003cbr\u003eOverall this makes for a quieter, more neutral, musical, and versatile control center for your system.\u003cbr\u003e\u003cbr\u003eThe XP-22 measures spectacularly well — but it really stands out sonically.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eOwnership:\u003c\/b\u003e\u003cbr\u003eSecond Owner\u003cbr\u003e\u003cbr\u003e\u003cb\u003eConnections:\u003c\/b\u003e\u003cbr\u003eXLR, RCA, IEC Power\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral Sound:\u003c\/b\u003e\u003cbr\u003eSmooth, uncolored, undistorted natural and clean\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCosmetic Condition:\u003c\/b\u003e\u003cbr\u003e9\/10 = Excellent.

Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. \u003cbr\u003e\u003cbr\u003eWhen we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface.\u003cbr\u003e\u003cbr\u003eThe first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1 KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope.\u003cbr\u003e\u003cbr\u003eWe then switch to a 1 KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment.\u003cbr\u003e\u003cbr\u003eOnce the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is used to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and\/or outputs these are tested as well.\u003cbr\u003e\u003cbr\u003eWe finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected.\u003cbr\u003e\u003cbr\u003eIf the preamplifier has remote control functions these are also tested. Preamps with tube circuits or complicated power supply topologies are connected at our long term test rig for extended stress testing under real world conditions.\u003c\/p\u003e","brand":"Pass Labs","offers":[{"title":"Default Title","offer_id":47623135592702,"sku":"107163","price":0.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/pass-labs-xp-22-dual-chassis-analog-preamplifier-943.jpg?v=1765916011","url":"https:\/\/skyfiaudio.com\/en-au\/products\/pass-labs-xp-22-dual-chassis-analog-preamplifier","provider":"SkyFi Audio","version":"1.0","type":"link"}
