supercharger Posted October 14, 2024 Posted October 14, 2024 Hi All, I have an article from Australian HiFi Magazine in digital form. It doesn't give the date, but I think it is from November 2007. The article is about the Musical Fidelity Supercharger 550K monoblock amplifiers. The PDF I have has pages 22-4, 26 and 28. The reviewer is named as Jutta Dziwnik, and the test results are reported by Steve Holding. My problem is that on page 26 Steve refers to the harmonic distortion graphs. These are not reproduced. I suspect they are on page 25 or 27, the missing pages in the PDF. Does anyone have a copy of this edition of the mag? know where I can get to see these graphs?

ray4410 Posted October 14, 2024 Posted October 14, 2024 (edited) hi Phil i found the Australian HIFI mag that you are referring to it was issue sept/oct 2008 the pages 25+27 are full page ads for other stuff so i think you have all the info that was about the MF 550K .

No lab tests further on in the magazine , they have a habit ( or used to) of splitting the review and lab tests through the mag?

betty boop Posted October 14, 2024 Posted October 14, 2024 ha ... i remember reading that edition back in the day good on you guys for keeping copies of these 1
supercharger Posted October 14, 2024 Author Posted October 14, 2024 WoW! Great work Ray. I appreciate it! That front cover photo is so cool. Its the only detailed image I have seen of the amp with the covers off. They must have forgotten to print the graphs! I don't suppose there was an errata in the November/December issue? or even a letter to the editor saying 'where are the graphs!'? Phil

Phil if i come across any more info regarding the MF550 i will let you know,if memory serves me well i am sure there were reviews in the English magazines/HIFI CHOICE/HIFI+/HIFI NEWS/HIFI WORLD it may be worth even checking out the USA mags Stereophile+ The Absolute Sound online for their reviews good luck Ray. = 6 hours ago, supercharger said: WoW!

Darryl Posted October 14, 2024 Posted October 14, 2024 (edited) I posted this in another thread a few months ago. It's an online archive of English HiFi mags, amongst others. If you search issues around year 2008 or so you'll probably find more reviews. https://www.worldradiohistory.com/UK/ Edited October 14, 2024 by Darryl 3

I have the two Stereophile reviews - one excellent, the other quite negative! I also have the HIFI NEWS review magazine on the way from an ebayer. There is also a tech Radar review here https://www.techradar.com/reviews/audio-visual/hi-fi-and-audio/amplifiers/musical-fidelity-550k-supercharger-275538/review. I'm especially interested in actual measurements. The wordy reviews are a problem for me as they are never listening to the sort of music I'm interested in so the comments lose a lot of their meaning!

Anthony1 Posted December 4, 2024 Posted December 4, 2024 All, I too have a copy of that magazine. I seem to recall that if you wanted to see detailed test results you contacted them. I did that a few times. Steve Holding still does tests doesn’t he and for sure he would still have the Distortion graphs your after (but Steve’s description of the second and third harmonic distortion components are specified in words instead). I would contact Aust HiFi and pray they get back to you. Jez Ford contributed articles even back then, Greg Borrowman should be contactable and Edgar Kramer is contactable. 1

Thanks, It's just odd the text refers to a figure that isn't present. I guess the editor decided there was no space for it and cut it, but forgot to remove the reference. I'll contact the people you mention. I'm still enjoying the superchargers, have built a musical fidelity x-ponent system around them, with two B&W PV1 subs. I think they are in harmony with the aesthetic. Tempted by some silver and black Kef XQ5's to finish it off, but love my Usher's so not sure. 1
