Perfect for someone considering an MA5300 but is fine with an older DAC. \u003cbr\u003e\u003cbr\u003eIt is rated for 100 W into 8 ohms, but actually puts more like 130 W with 0.005% distortion. It also features a great built-in headphone amp capable of driving the best headphones without additional equipment. At the rear of this amp includes digital inputs for connecting a CD transport or digital source easily plus balanced XLR inputs. These two featuers together on integrated amps are uncommon and it is welcome to see them here. \u003cbr\u003e\u003cbr\u003eKey McIntosh features include Power Guard and Sentry Monitor protection circuits. Power Guard helps prevent audible clipping by automatically reducing input drive when necessary, while Sentry Monitor provides fuse-free short-circuit protection that automatically resets once normal operating conditions return.\u003cbr\u003e\u003cbr\u003eAnother really cool feature of McIntosh units from this era is their coveted fiber-optic lighting.

Select Series Reference USB Cable\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTesting Process:\u003c\/b\u003e\u003cbr\u003eWe start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. 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\u003eIf the device has the ability to decouple the preamplifier from the power amplifier, we remove the jumpers and independently test each section. If the device cannot be decoupled, we assess the electronic condition of the piece by analyzing the speaker level output only. \u003cbr\u003e\u003cbr\u003eWe start by connecting the \"Pre-Out\" jacks of the integrated to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface. The 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.\u003cbr\u003e\u003cbr\u003eIf the preamp section 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.\u003cbr\u003e\u003cbr\u003eNext we test the power amplifier section by connecting the integrated amplifier speaker outputs to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1 KHz test signal at the \"Main In” jacks and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping.\u003cbr\u003e\u003cbr\u003eAt this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. We finish off the bench evaluation with a 1 KHz square wave check and a 20 Hz to 20 KHz sine sweep to assess the amplifier’s frequency response characteristics. \u003cbr\u003e\u003cbr\u003eThis battery of tests will usually reveal if the amplifier has any issues that need further attention. \u003cbr\u003e\u003cbr\u003eIf the preamp and power amp both pass these tests, we reconnect the sections and verify that the preamp section can drive the power amp to rated power with a 1KHz tone on one of the line level inputs. \u003cbr\u003e\u003cbr\u003eBefore the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics. \u003cbr\u003e\u003cbr\u003eIf the unit passes all of these tests it moves to our long term testing rig where we simulate real word operating conditions for 6-8 hours minimum. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature.\u003c\/p\u003e","brand":"McIntosh","offers":[{"title":"Default Title","offer_id":48964848713982,"sku":"108040","price":4990.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/mcintosh-ma5200-solid-state-integrated-amplifier-158.jpg?v=1789495634","url":"https:\/\/skyfiaudio.com\/products\/mcintosh-ma5200-solid-state-integrated-amplifier-pre-loved","provider":"SkyFi Audio","version":"1.0","type":"link"}
