oleg Posted November 12, 2011 Share Posted November 12, 2011 Please help to choose a right amp for my Klipsch Palladium F37 and JM lab 1007 BE speakers . My current setup is a Harmon Kardon VCR645 as a preamp and Cambridge Audio Azur 840W as a power amp. The Harmon Kardon also feeds my desktop Focal JM lab 1007 BE speakers. Focals sing perfectly but the palladiums are too bright for my test so I decided to replace the current setup with a soft music reproduction integrated amp to fix it. The SS amps from the list have ability to drive A or B speakers so one of them should match both pairs of my speakers well. Palladiums are priority! 1. Luxman L507U/509U 2. Luxman L507S 3. Mcintosh MA6450 4.Accuphase E460/350 The problem is I do not have apportunity to audit the above amps with my Palladiums. Which amp from the list matches the Palladiums (make them softer) better? I appreciate any help. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted November 12, 2011 Share Posted November 12, 2011 McIntosh MA-6400, 6450 (if you do not need a turntable or headphones), 6500, 6800 or 6900 will do them justice. In addition, Mac would be the most long term reliable. Depends on your budget. Quote Link to comment Share on other sites More sharing options...
Colin Posted November 12, 2011 Share Posted November 12, 2011 Any amplifier is not THE amplifier. Manufacturers quoteTotal Harmonic Distortion (THD)for at their amplifiers’ highest wattage output. But THDis not the same for all types of amplifiers. Since big ole Klipsch horns actuallyneed only a few, generally three to six, but usually not more than 20 or 30 watts,these watts – milliwatts most of the time - must have very low distortion. Becauseof their own exceptionally low distortion, big ole horns are extremelyrevealing of anomalies upstream, including the amplifier’s THD. If a component has lots of distortion at lowpower, the speakers can sound harsh. Odd-order harmonic distortion(http://en.wikipedia.org/wiki/Tube_sound),in particular, sounds harsh. Which types of amplifier have lots of odd-orderharmonic distortion at very low wattage? Solid-state. I have heard the wonderful $6KPass X250 (http://www.enjoythemusic.com/magazine/equipment/0202/passx250.htm)amplifiers on my B-2 Cornwalls Is, and yet my 3-watt $550 2A3 tube BottleheadParamours (http://www.enjoythemusic.com/Magazine/equipment/1202/bottleheadparamour.htm)can sound just as sweet, when they are not clipping. Powerfulsolid-state amplifiers do have headroom so loud passages at high volume haveconsiderable slam. They also have excellent woofer control so both bass andmid-range sound solid. Yet not everybody appreciates the soft clipping oftubes. But to me, all but the very best solid-state amplifiers on big ole hornswears out my ears. I would get the VRDs in a heartbeat, otherwise the Mac is the one to beat. Quote Link to comment Share on other sites More sharing options...
artarama Posted November 16, 2011 Share Posted November 16, 2011 I have not heard any of these either, but from my voyeristic reaserch conclusions I would go for the 509U. Maybe a plane ticket to hear some of this stuff first hand should be in the budget. Maybe the "soft music reproduction" goal to "fix it" may point you to a quality tube preamp. I would love to hear the SQN100 tube integrated. $2,100 + $250 frt to check this one out! The price of an education can get pretty expensive!
