MUSE Model 300 repair & upgrade

So glad I found John who was able to advise on repair and upgrade options for these old amps, they’ve been repaired twice before so I wanted to make sure they stand the test of time. Decided to go the whole hog which entailed: – upgrading the toroidal transformers from 500VA to 1000VA (custom built […]

P150 Repair and Upgrade

I’ve deliberately delayed submitting this review to let the amp settle down and bed in but I’m very impressed. The control and clarity that the amp now has would cost an awful lot of money if buying new but this is achieved without sounding clinical just smooth authoritative powerful sound it’s an addictive mix. I’m […]

KW 250s

Now that I have had time to listen properly and to after a lot of tinkering with my system finally got to a place I am happy with I feel able to review John’s work. The first most obvious difference was that the sound seemed airier. More space around the notes and instruments, generally more […]

Musical Fidelity NuVista 800 Upgrade

John recently carried out a stage two upgrade on my Musical Fidelity NuVista 800 Amp. His work transformed what was already a good amplifier into an excellent one that has sound quality of a much higher level of quality. The soundstage is precise, realistic and has excellent composure making listening to music even more of […]

JS audio gave my A100 a full rebuild for £600. I have had the amp home for around two months and used it daily. I left it a little while before leaving a testimonial ,to be as helpful as I could to anyone considering this for their amp. I totally recommend the service, the a100 […]

Musical Fidelity X-Can V3 upgrade

Thanks so much for the uber upgrade carried out on the X-Can! Early impressions are… stunning! Works very well with my Sennheiser and Beyerdynamic cans but pairs magnificently with the QUAD ERA-1’s. Actually, I am blown away by how good the pairing is – a match made in audio heaven! I wasn’t prepared for the […]

New life for a veteran CD player

On the back of John’s superb upgrade to my Nu-Vista 600 amp, he assured me that a repair and upgrade to my 2005 MF A5 CD was going to be money well spent. The player had been failing to read discs for a while until it got so bad it was unusable. It always had […]

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 […]
