Simply in one word - 'superlative'...
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!
I have been intending to do a review for ages; so apologies to John for the lateness!
Over the last few years he has repaired & or upgraded all my Musical Fidelity kit (F15 amp, M6 Pre amp, M250 mono amp, 550K superchargers)
to the point where every listening session or film viewing is transformed into an event (dare I say getting a "fix")!
As others have said the results speak for themselves and I can only recommend his services as second to none, including technical advice over the telephone. A gentleman in every sense of the word.

I've had these upgraded for quite a time now and what has become more and more apparent is that the hardware responds transparently to any changes you make. I've upgraded my speaker cable and interconnects (several interconnects) and the changes are as clear as day. This allows me to fine tune my system to suit my taste. Brilliant!
I couldn't have asked for more and John has been more than helpful on the odd occasion I've had a question.
Expensive - yes, but excellent value for money. Buy with confidence.
Whilst contemplating getting a newer and more expensive integrated amp, I stumbled upon a recommendation for John's service. After swapping a couple of emails I decided on upgrading my amp, expecting to gain subltle and at best moderate improvements.
My expectations have well and truly been exceeded, the NAD is now producing clearer and more defined bass, a midrange that is a level or two better than before and with a sweeter upper range. It is if a blanket has been removed from my speakers, in fact I am now appreciating how good my speakers are!
Great service and great results. Thank you John
I met John when he still worked for Musical Fidelity. He carried out upgrades/repairs to both my F22 pre and F19 power amps a couple of years ago and both are still going strong. His work cannot be recommended highly enough.
