Musical Fidelity kw500 amplifier, and psu some independant reviews STRENGTH: Practically unlimited power (I use Usher BE 20 speakers), built like a tank, excellent sound from ultra low to god knows how loud (I have never played it above one’o’clock). Extremely detailed, lot’s of “air” in the treble, full and detailed midrange, and precise, and very controlled bass, all integrated perfectly. STRENGTH: Incredible power. Transparent. Excellent channel separation. Best of tubes and solid state. Decent phono stage for high output MC cartridge. Beautiful resolution, great speed, awesome bass and dynamics, tube warmth, top notch build and reliability, low heat, limitless headroom and power, shames seperates costing the same. STRENGTH: If you are looking for NATUREL sound, DETAIL, SOUNDSTAGE ,WARMNESS OPEN sound and IMPACT?????? Well You will have to try that rig! ITs fantastic ! You will easilly forget his 500 watts of power ! WEAKNESS: None so far ! STRENGTH: In my opinion, the combination of powerful dynamics, rich detail, and strong bass is what makes the sound of this setup so intriguing and enjoyable. I simply cannot wait to hear how this thing sounds with the new 3.6/Rs after some break-in time. I think its going to be a real treat. WEAKNESS: Not that it matters to me, but this contraption is massive. Id be worried if I was putting it on anything less-than-extremely-sturdy. Also some people will think the remote is too flimsy for something this expensive; I dont care myself. At times, the sound could be too bright if you dont take care to position your speakers or treat your room properly. The only design change Id like really to see: The addition of a pair of balanced XLR inputs. I just cant imagine why an amp of this caliber doesnt have them already. BACKGROUND: Ive had the Musical Fidelity KW500 for a couple weeks now. Ive been playing it exclusively through a pair of Magnepan 1.6QRs. (Im awaiting delivery on a pair of 3.6/Rs, and bought this amp specifically for that reason.) The speakers are bi-wired through a set of Speltz magwire anticables. The amp has four speaker terminals on each side specifically for bi-wiring, so I decided to just take advantage of them and not worry about the minor addition in cost and whether this really improves the sound noticeably. The signal source is a Benchmark DAC1, fed by a Slimdevices Squeezebox 2 run digitally through a Behringer DEQ2496 equalizer for room correction. About 95% of my music collection is ripped in FLAC, and its heavily weighted towards electronica (but NOT techno), with a healthy dose of modern rock, punk, jazz, funk, classical, and a little bit of everything else under the sun. My room is about 15 x 20 with wood floors, an area rug, and a fair amount of furniture. I tend to listen at fairly high volumes most of the time, thanks to a cool wife and neighbors. THE UNIT: In summary, its a hybrid integrated amp with about 500wpc at 8 ohms. The preamp is tube driven with military-spec tubes that are supposed to last a lifetime. The amp is constructed in two pieces: The power section has its own separate housing, and it connects to the main unit via three umbilical-type cords (one for the preamp, and two for each side of the power amp). Together, both sections weigh 100 pounds! The fit and finish on this equipment is simply unsurpassed. Ive owned Musical Fidelity gear before, and Ive certainly found it to be well-constructed, but this thing is just ridiculous. Im not kidding; it is built like a ****king tank. I understand most of MFs stuff is manufactured in Asia now, but this line is still built in Britain. I believe it. This thing could have survived a few dozen Nazi air-raids and then some. The volume knob on the front of the main unit is about 3.5 in diameter, and turning it feels like rotating the dial on a 500-pound Acme safe. Each section has two large, black handles(?) on either side of the front that dont really work as handles, so I dont know what purpose they serve, other than to make it look tough. (Maybe you can rack-mount it somehow, but its hard to imagine, quite frankly.) The appearance wont win any beauty pageants, unless theyre held in East Germany ca. 1970, but I dont mind it personally. The only semi-attractive parts are the lit-up feet on each unit. They start out red when you power up, turning to amber after 6-7 seconds, and then to electric blue after warming up a half hour or so. Theyre kind of gimmicky, and I personally cant tell any difference in sound between the amber stage and the blue stage, but Im sure some people will take special satisfaction in know their music is playing at the right color. SOUND QUALITY: In my opinion, and in my setup, the sound quality is absolutely astounding. This amp will clearly not be to everyones tastes. It is *extremely* aggressive with dynamics and transients. Many listeners will undoubtedly prefer a more laid-back, smoother, more musical sound. But personally, I have never heard anything so attention-grabbing and realistic sounding. This is music that grabs you by the ears, and forces you to listen. And I love it! The tone is perfectly neutral and crystal clear. Initially, it seemed too bright at times, but I was able to work with speaker placement to ensure it didnt become unpleasant with mid-treble-heavy music like horn sections, etc. I suspect I was simply getting some badly placed reflections off the walls, furniture, etc. Now it sounds absolutely perfect. The level of detail from this combination of amp and speakers is like nothing Ive heard. I constantly find myself doing double-takes when a certain sound seems right there in front of me with an uncanny degree of realism. The soundstage is wonderfully wide and deep, despite the fact that Im unable to position the speakers optimally because of how the room is laid out. The bass is the best part. It is extraordinarily rich, utterly satisfying and downright earth-shaking given the limits of these speakers. Standing between the speakers at loud volume, I can feel the floorboards flexing beneath my feet. People had told me not to expect more bass out of a more powerful amp. I expected them to be right, but now Ive concluded that they are simply wrong. This thing actually makes my 1.6QRs punch like a welterweight. They sound distinctly un-Maggie-like in this department. They arent quite like JBLs, but for the first time, I can really feel the bass substantially, like I could never feel it with other amps driving these speakers. Before this amp, Id been driving the 1.6QRs with a Pathos Logos with 220wpc @ 4 ohms. I thought for sure that was plenty of power, but now I dont think so. Ive heard many people say Maggies need loads of power to sound their best, and for my tastes, theyre absolutely right. Some folks say you can drive Maggies with a few high-quality watts from a tube amp, and if what you want is a pleasant, musical smoothness at low volumes, then thats fine for you. But if you want serious dynamics and attention-grabbing realism at loud volumes, you really need serious power. I Track Page Views WithAuctivas Counter
