My X-A100R

Item Repaired/upgraded: Upgraded 

What a contrast... I had John upgrade X-A100R amp which has been part of life since 1999... I decided that vintage is the way forward and luckily enough Ebay seller Clifton from Eastcote had a set of near perfect MC-5 speakers up for sale... The upgraded X-A100R and these MC-5 speakers are unreal... Task... How do I connect the 2 pairs of MC-4 speakers to this setup without having an ASBO???? .... I am stunned and enjoying the sound and depth from the amp coupled with some sublime speakers..... Thank you John... Great Stuff!

A3 CD awesome upgrade

Item Repaired/upgraded: Musical Fidelity A3 cd player 

Some time ago John upgraded my Musical Fidelity XP100 pramp to great affect, this has a great phono stage which is why I have kept it all these years, I told John that the sound through my record deck was better than the sound I get out of my Musical Fidelity A3 CD player, he said that he could do a great upgrade on the A3 and it would sound as good as my vinyl player and properly better.
Dose it sound better,//, Iv'e been playing the A3 for around 4 weeks now and the improvement is massive, cleaner more open sound, bigger sound stage, heaver and tighter bottom end, the overall sound is much more dynamic. AND GETTING BETTER
As for sounding better than my record deck well it's close, it depends more on the better recording now which comes out on top, I find I am happy listing to my CD for longer periods as they sound so good.

So once again John thank you very much, I am very happy with the A3.
you are a master of your art

Kind Regards


KW500 transformed

Item Repaired/upgraded: Repaired and upgraded 

I was hearing eggs frying on one channel of my KW500, so it needed fixing. With so many positive reviews, I opted to go for the full Monty upgrade. That was one year ago, and it just seems to go on getting better and better. I mainly listen to classical music, and my Hi-Fi holy grail has been to close my eyes, and imagine that I am in the concert hall, or opera house, listening to a live performance. Before the upgrade, I had the sense of a performance in front of me, but not actually being there. Since the upgrade, I have got inside the venue, and the performance itself has been transformed. The sound stage is huge, with width and depth. Less than stellar recordings have come to life, and the best recordings are overwhelmingly. It’s so like going to a live concert, that I want to applaud at the end!

Nu Vista Nirvanna

Item Repaired/upgraded: Repair & Upgrade 

Nu Vista M3 Intergrated WHAT A DIFFERENCE! I paid MF for an upgrade over 10 years ago; I'm sure I didn't get my own amp back, and the amp I got back didn't sound any different. The amp recently had a fault dropping the right channel intermittently. I called John who immediately stated the selector switch was the culprit which gave me confidence, so I went for repair and upgrade. Bloody hells bells; after a few days burn in I still have the MF NU VISTA sound, but with more clarity; and where did that extra bass come from? As John said when I collected "it's all the amp You'll ever need". Must get the Nu Vista CD done next. Thanks John I'm very impressed.

Simply in one word - 'superlative'...

Item Repaired/upgraded: MF NU Vista 800 

I have intentionally left leaving a review for a number of months so that I can give an 'as is/accurate' type of review; I should add because of my scenario (SCI) that I listen to my music way more than the average listener (sometimes up to 8 hours a day).
As the review title says, if I had to use one word it would be 'superlative'.
I will say what was (overall) already a very capable amplifier, is now absolutely superb in 'all' area's - if I had to choose just one, it would be clarity/resolution.
Over the years I have had demo's of numerous, mostly higher end Hi-Fi and without any doubt can say this is now truly the best I have heard to date.
Obviously Hi-Fi is a very personal/subjective thing, but to my ears this now runs circles round the usual contenders/suspects in this context.
John was extremely helpful from beginning to end and I cannot recommend his help, service and advice enough; like the majority of us here, John has an obvious passion for music/getting the absolute best out of equipment and even if you are understandably hesitant (as was I), do not be! - once you have your equipment back, run it in 'well', I will be truly amazed if you are not as happy as I am with the results!
Thank you once again John for your knowledge, workmanship and ultimately... results!
