kw550 takes a deeper breath
kw550 takes a deeper breath My beloved kw550, after more than 10 years of service, blew some transistors in a heart wrenching pyrotechnic display. Along with the quote for repair and a upgrade to the kw550, John gave some sound advice on why the load might be the cause of the demise of the amp. […]
Never sounded so good!
I just received my 2 Musical Fidelity A3 units back today from John and it’s like Chrismas here in Stockholm. I did have a back up system running all summer, but to get my A3 amplifier and A3 CD player set up again afer a stage Two upgrade in just fantastic. I don’t think the […]
Nu-Vista Pre repair
John Thanks for the repair to my Nu-Vista Pre today. Appreciate the time you gave me and the discussion about upgrade options for the NV Power amp. Fantastic service from a nice guy. Thank You.
5k power amp now sounds like £20k power amp
I’ve owned two MF amps , the m6i , then upgraded to the m8500s , I found the sound of the m8 to be very clean, low distortion/noise and with endless authority and I thought I would keep this amp forever, £5k is an awful lot of cash for an amp and I thought this […]
JS Audio Upgrade Magic
John very kindly repaired my kW CD transport, and when I collected it we discussed how much better my kW500 would be if upgraded so I went for the complete package including the power supply upgrade – the man has magic fingers! What a transformation, the depth and control that this amp has now is […]
Musical Fidelity M3
I upgraded my speakers to B&W 803 D3’s and was looking to improve my AMP and fix a dirty input selector without buying a new expensive AMP. I gave John my M3 AMP and he performed his stage 2 upgrade. It was well worth the upgrade and price was very reasonable for the work carried […]
It’s all about the music, silly!
Thank you for the return of my upgraded X-ACT which I have used with my Roksan K3 CD player as transport. I have listened to a dozen or so discs so far and can say without contradiction that, considering the extent of the improvement, this was the best £130 I have ever spent on my […]
MF Nu-Vista 600 sounding big
I have loved my NV-600 from the off for its combination of unfatiguing smoothness, detail and power, but was curious to take it as far as I could, seeing as it will be a destination amp for me. Interestingly I actually preferred the sound overall to the NV 800, which to me, sounds a little […]
MF NuVista800 improved
The unmodified NV800 is a very capable amp and one of MF’s best big integrated amps in stock form. It has clarity and detail but with a tendency to sound a touch soft and held back. Having had previous experience of JSAudio MF upgrades I knew the amp had more to offer. John’s upgrade takes […]
Upgraded amp
After owning my KW500 for a couple of years I decided to go for the Stage 2 upgrade. This was after reading all the glowing reviews here and I have not been disappointed! After running it in for a while the sound has improved no end. Dropping off and collecting the unit was easy and […]
