One of the most common Magnepan clichés I read is 'they need power' which is why I originally thought to try some cheap used Crown XLS 2500's which were a vast improvement over my Maggie dealers $3k Rotel option. Thanksgiving weekend at a point when my blood sugar was probably too low I saw a Black Friday online add for a Crown Macro-Tech 5000i which may have been mistakenly priced too low. I confess I followed the shiny object. It's watt specs are: 2Ω 20mS BURST 2Ω 20Hz-20kHz 4Ω 8Ω ---------------------------------------------- 3000W 2000W 2500W 1250W It is advertised as stable to 1 ohm. The result is a different pair of speakers. I keep going downstairs to make sure its real. Objectively per REW the SPL below 200HZ goes up relative to the SPL above 200HZ. I typically sit about 8 feet from the back wall. At 2 feet from the back wall 20 to 30HZ SPL matches SPL above 200HZ. Symphony wise, depending upon the recording as always, there is far more clarity of and volume of say double bass and bassoon. Bass drums rumble as intended and tympani clarity can startle. The level of detail for all instruments is much greater. And I could go on and on. This amp connects to my laptop and shows input, output and load levels. It has volume rather than gain knobs like the XLS. My Oppo which is connected directly outputs 4.2v and the default input on the Crown is 1.4v so at first input clipped constantly. I had to set the sensitivity to 26DB to stop input clipping or turn down the Oppo's output using its digital volume control which seems to affect quality. I mention this because I don't recall every reading about input clipping as a problem in audiophile land. When I added my pair of DWM in parallel the load dropped below 2 ohm which explains why I and others have seen paralleled DWM's turn amps into space heaters. The statement I read somewhere from someone who's name I will not mention that 'they don't draw that much' doesn't seem to be quite complete enough. So far this amp experience suggests that More Power diminishes the need for DWMs and my Rythmik sub which I find amusing at least. Oh well back to researching Lab.Gruppen, AES digital inputs and pro amps with DSP EQ. |

That is for the XLS2500 not the MA5000i |

(bridged 4 ohm)that's a lot of juice flowing through a pair of old ladies : ) article |
I'd say grab that one because , posted on December 8, 2016 at 19:57:41 | |

Yes, these amps are something else. You need to hear how much bass they can blast out of a Tympani. |
