servicing feedback, yes it really makes that much difference..
I have just got my 20+ yr old Lingo 1 back after
a service and re-cap from these guys, I didn't think there was anything
wrong with it but had been reading on here how they go off with time....
WOW, they were
not wrong, it is not subtle, it is astounding, if someone told me I
was now listening to a Radikal I would believe them, if you have an
old Lingo that has not been re-capped it's a must, I can honestly
say it's the best £85 I have ever spent on hi-fi

Customer feedback from a serviced Lingo
Just giving you some
feedback on the service you carried out on my old Lingo power supply
last week. To say I was impressed with the improvement to my system is
an understatement! Everything is back where it should be, the bass is
deeper and more realistic, the drums actually have skin on them and the
vocals sound fantastic. The system is now back to it’s former glory,
more musical with the soundstage more three dimensional and you can
follow every instrument. It’s as big an improvement as when you serviced
my Naim amps several years ago.
For anybody with an
old Lingo they would have to have their heads examined if they didn’t
have this service carried out and all for £80 - £140. That applies to
anybody with elderly Naim amps obviously at a different cost.
My system by the way
is a Linn LP12 Ekos arm and Akiva cartridge, Naim 250, 32.5, Hi-Cap amps
(Chrome Bumpers) and Dynavector 2/6 Loudspeakers.
Due to the very popular birthday promotion we
have decided that the reduced service prices will now remain in place

A couple of great quote from the Naim forum...
I had my 82 serviced a couple of years ago - this after having
nothing done on it for some 20 years. Can honestly say it made a
significant improvement and was well worth the money.
I suggest you
speak to an expert like Darran at Class A; he will answer your question
about servicing and POTS8 upgrade. I asked about having the latter done
and he said the difference was minimal and my money could be spent
better elsewhere! An extremely honest and helpful guy who has a
reputation for excellent service.
When Darren serviced my 32.5 a few years ago (it's first ever
service) there was a significant step forward in SQ. Well worth it. Age
dependent, of course. Darren can advise, and will only replace/repair
what is required. Extremely quick, expert and friendly service.

It has just been brought to my my attention that a guy in USA is
trying to sell a Nait 1 supposedly serviced by me last year. It is an
obvious scam as all the details are incorrect.
If you are looking at
buying an item I have previously serviced then please contact me first
with the serial and invoice numbers so I can check the validity before
an expensive mistake could be made.
1st March 2015
How good can old Naim equipment sound ? VERY according to
this satisfied customer..
I collected my 30 year old Naim NAP 110 & NAC 42
and, after warming up, I listened to several records.
The work you have done was absolutely outstanding. I heard things
and background orchestral sounds more clearly than I recall.
Listening to Elgar's Cello Concerto played by DuPre I heard a member
of the audience cough - quietly but quite clearly.
I am now looking for a SNAPS power supply for the pre-amp. When I
find one you will restore it if it has been modified and service it.
However, your work was amazingly good - well worth the money.

A quote from the Naim forum from a customer happy
with his freshly serviced Naim Nap-135's..
We service Naim
units to 100% Naim specification, with no dubious
upgrades or modifications...
I have 2 pairs of 135s ready for the "floaty" snaxo,
whenever that will appear. one pair was last
serviced 2006 and even though it sounded very good
driving SL2s, i wondered what it would be like
serviced -- since
its failry close to the 10year threshold.
week, i stopped "wondering" and sent it to Class A,
collected last Tuesday -- back serviced today --
delivered this morning!
When they were
delivered, the cases were almost freezing to the
touch so I left them on the floor in my office to
"thaw" a bit.
This evening i connected them up,
let them playing radio for a couple of hours.
Since around 1900hrs, i have been playing music --
the serviced 135's now actually sound a even better
than before the service -- i guess that much is
obvious -- but what i wasnt prepared for is how much
better -- they are a LOT better!!
I have been
through NAP200, NAP250(both passive and active)
NAP300 (both passive and active) and now on 135s
(currently passivle, but will be active when the
floaty snaxo sees light of day).
sound so good that I am having difficulty figuring
out in what ways the 300 betters them
to the music...
I have used you for Naim service a few times
in the past and each time the outcome has been the same
-- highly improved performance from the serviced
equipment and I am grateful for that -- and long may it

very happy to see decks making a come back.

Time for a clear out.
Over the years I have obtained 100's of
original service manuals for audio and hi-fi equipment, these are now
taking up too much space so it is time to move them on. I will soon be
listing them on Ebay.
These are for Technics, Kenwood, Denon,
Sony, Pioneer etc. and include amplifiers, tuners, cassette decks, cd
players. and turntables.
If there are any of use to you please
These are original
manufacturers service manuals, not copies.

Added a new section
Check out the downloads
section, I will be adding user manuals mainly for Linn amd Naim

please contact me and I will add them to the list.
23rd October 2012
The info from Naim is all the upgrades will have to go back to Salisbury
as no dealers will be allowed to carry out the work themselves.
Also only the current range of products will be accepted so
unfortunately Olive or Chrome bumper equipment are not upgradeable.
If interested you have to register your interest via the Naim website or
your local dealer, they will then give you a total cost, including a
reduced cost for servicing if required and give you a time slot for the
when the work can be carried out.
Jobs are done in order of registration.
The other option which many people seem to be considering is, depending
on age, to trade the units in for brand new DR fitted products, some
dealers are offering very good trade in values.

forward to seeing you.

Naim's New DR Power
Following a two year development project
Naim has announced it has updated its power supplies to feature a new
discrete regulator that greatly improves performance. The new Naim
Discrete Regulator (DR) will be fitted to the HiCap, XPS, SuperCap, 552
PS and 555 PS power supplies as of May 14th 2012.
Building on Naim’s upgrade path philosophy
The addition of outboard power supplies
offers an established upgrade path for many Naim products. By improving
the supplies themselves, removing the electromagnetic field of the
transformer and interference generated by the rectifier diodes, and by
eliminating transformer vibration from the product case, Naim power
supplies offer improved sound quality.
The role of the regulator
Voltage regulators are widely deployed
within Naim power supplies to ensure that audio and digital circuits
operate with a stable, low noise supply voltage, thereby maximising
their performance. Naim’s new discrete regulator betters industry
standard monolithic voltage regulators and, even more importantly, has
had its design and component selection refined in the listening room to
deliver maximised sound quality from Naim’s audio circuits.
A pure development project
As well as incorporating the newly
developed DR in these five power supplies, Naim has reviewed and
optimised every aspect of their design. Transformer mounting, wire
gauge, wire routing, mechanical decoupling, internal layout and
reservoir capacitors have all been scrutinised to ensure that the DR’s
benefits are fully realised. The result of the inclusion of the new DR
regulators and the updates to design is a quite significant increase in
performance which helps the listener to really connect with the artist
