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 […]
Musical Fidelity Tri-Vista 300
The left channel of my Tri-Vista 300 integrated amplifier stopped working. Despite the lock-down, John was able to source the components to repair the unit (new valves were needed) as well as perform an upgrade. The repaired amp really does sound very special indeed.Once it has warmed up the depth, richness and musicality is remarkable. […]
A master at work
never thought my particular kit could sound any better than it already did but after John had worked his magic on it I have to say I’m totally amazed by the sonic improvements so like most on here I have no option but to give a 5 star rating and to say thanks a lot […]
