Magic requires time and skill
Well. After nearly 1 year my Musical Fidelity XA200 amplifiers are back at home. They sound beautifully, I’m afraid not being able to find more subtleties in the sound; to me, they sounded great also before the repair/upgrade. In fact, they sound(ed) so good I am cold when I listen to some ‚Äúsuper systems‚Äù at […]
Meridian Upgrade
M100 speakers are over 30 years old and had never been serviced. John replaced power supply caps and input sockets. (the originals feel off) He also worked some other magic to the speakers. The G92 had a new power supply and again other magic. The character of the system is the same, I love it. […]
A100 reborn
I decided to get my old A100 renovated as it was my first , proper’ Hi-Fi amplifier and I missed its warm, mellifluous sound. I t had had a repair job some 15 years ago which had left it working but uninspiring to listen to. I contacted John who recommended a full rebuild and so […]
Repair/Mild upgrade
First of thanks John for your excellent customer service. Now for the review, Good News first I think. There is now doubt that just about ever category you could consider has improved. In some areas the improvement is vast (space, decay, attack, slam, bass depth, weight & extension). The largest improvement was however the silky […]

Amazing Transformation
I have owned a pair of John Bowers Active speakers since 2007 and although were working ok, I knew that there performance wasn’t anything like they should sound like. These ground breaking speakers were manufactured in 1986, some 33 years ago! I had used John Sampson to repair and upgrade the original music fidelity pre […]
Repair Refurbishment
I bought my Luxman 309 amp in sept 1976 and it has performed brilliantly. Over the years the sound started to decline and I put this down to my own hearing declining with age. Unfortunately one of the channels recently became intermittent and I then struggled to find anyone who could repair it. I was […]
Tremendous Upgrade
I’ve now put some 50hrs on my newly upgraded Cambridge Audio power amp. When I first got it home, after the upgrade, I was not sure what exactly to expect but the difference was immediately obvious. Within 20 minutes I detected improvements across the frequency range. Bass and midrange were most noticeably improved and my […]
Astonishing
In the audiophile world we talk about the law of diminishing returns; increasing investment for a marginal gain. When my MF A1000 came back from John there was nothing marginal about it. As soon as we powered it up for the first time the difference was astounding. I thought I already had a great amp […]
Craftmanship
“I admire the engineering skills and craftsmanship almost as much as I admire the sound of the Upgraded Graaf. It takes great skill knowledge and knowhow to do an upgrade on a piece of equipment. You can go to far and totally destroy the sound you loved so much. Having Knowledge and understanding of component’s […]
