The XS Series represents so much more than evolution. Behind
their brushed and anodised aluminium fascias, XS Series products
embody radical and innovative audio engineering that builds on Naim’s
previous slimline X Series to take performance to yet greater heights.
The XS Series comprises a CD player, FM tuner, integrated amplifier,
preamplifier, power amplifier and power supply, each one refined and
polished to offer flawless system matching and matchless performance.

CD5 XS CD Player
The CD5 XS CD player has probably seen the most changes on the journey from its CD5x predecessor. Almost every
element, with the exception of the mains transformer and the disc mechanism, is new or significantly revised. Fundamental
elements including critical analogue circuitry have been updated to extract yet more music from every CD. Also new in the
CD5 XS is the inclusion, for the first time on a Naim CD player, of a transformer-coupled digital output that provides the
choice of digital or analogue signal output.
Improving on the award winning CD5x was a tough ask, but through scrutiny and refinement of every last engineering
detail, the class-leading Naim CD5 XS delivers newly dramatic and vibrant music.
NAT05 XS FM Tuner
Apart from the benchmark and matchless ALPS high performance tuner head, the NAT05 XS tuner is a completely new
design. The tuner head is compliantly mounted within the aluminium casework and feeds analogue circuitry that benefits
enormously from Naim analogue know-how. FM remains the medium for the highest quality radio transmissions and the
NAT05 XS is optimised to exploit FM like no other tuner. And if you want more, the NAT05 XS can be enhanced further
through the simple addition of an external FlatCap XS power supply.
NAP 155 XS Power Amplifier
The NAP 155 XS is the perfect companion to the NAC 152 XS preamplifier in an XS system. It features a very large mains
transformer – both physically and in terms of its power rating – and at the heart of its power supply uses the same reservoir
capacitors as the award-winning SUPERNAIT integrated amplifier. The NAP 155 XS employs similar construction techniques
to the NAIT XS integrated amplifier with a castellated heatsink and reduced earth reference routing to deliver enhanced
performance and more music. The NAP 155 XS is a power amplifier straight out of the classic Naim mould: fast, detailed,
dynamic and single-mindedly musical.
FlatCap XS Power Supply
The FlatCap XS is a dual-rail power supply that, either alone or in pairs, provides the most effective means to extract the
ultimate performance from an XS system. One FlatCap XS can be used to enhance the performance of a CD5 XS and a
NAT05 XS, while a second could be deployed to supercharge the performance of the NAC 152 XS preamplifier. The vital role
played by the power supply in any hi-fi system is a long held Naim conviction and it has no better demonstration than the
increased musical fluency that the FlatCap XS brings to a system.

FlatCap XS
The CD5 XS, NAT05 XS and NAIT XS deliver
the finest CD and radio sound you will
experience from a compact system, albeit one
that effectively represents the first rung on the
ladder towards super-performance separates.
The capabilities of this potent trio can easily
be enhanced with the addition of a FlatCap XS
power supply, and extended further by moving
into the separates systems featured below,
with the NAP 155 XS power amplifier and
NAC 152 XS preamplifier combination.
Integrated System
Core System Upgrade Path
Bring together a NAC 152 XS
preamplifier, a NAP 155 XS power
amplifier and a CD5 XS CD player for a
stunning CD replay system. Make it even
better with a FlatCap XS powering the
CD player and the preamplifier.

FlatCap XS for the preamplifier and the
tuner, and radio has never sounded better.

The complete XS system of CD5 XS and
NAT05 XS, NAC 152 XS and NAP 155 XS
defines brilliant music making. Adding a
single FlatCap XS, which can power one
or two components, upgrades the internal
power supplies of the CD player, the tuner or
the preamplifier, making your system shine
even brighter. The system’s performance
can be further enhanced with the addition of
a second or even a third FlatCap XS, each
powering one component.

Core System Upgrade Path
NAC 152 XS Preamplifier
When a separate preamplifier/power amplifier approach is preferred, the NAC 152 XS provides the perfect option. It was
conceived around a completely new motherboard design that incorporates advances of both analogue electronics and
mechanical decoupling, and its performance is detailed, refined and utterly musical. Versatility is a NAC 152 XS forté too. Its
six analogue inputs all offer DIN or phono connection options and it incorporates a front-mounted, auto-switching input socket
for convenient MP3 player use. Power output for a Naim phono preamplifier is also included and a two-stage power supply
upgrade regime brings true high-end preamplifier performance easily within reach.
NAIT XS Integrated Amplifier
The NAIT XS takes the DNA of our best ever integrated amplifier, the SUPERNAIT, and, like a sports car stripped back to
essentials for the track, delivers musical performance that truly inspires. The 60 watts per channel power amplifier section is a
dynamic, fast acting musical muscle with an uncanny talent for bringing speakers to life. And the preamplifier section provides
all the musical clarity and detail you could wish for. The NAIT XS is versatile thanks to six analogue line inputs on a mix of DIN
and phono sockets, a phono preamplifier power supply output, and a front panel mounted auto-switching mini-jack. Like the
rest of the XS Series, the NAIT XS is genuine high-end hi-fi brought within reach.
