Za tiste sladokusce ki želite okusiti kvaliten zvok iz devedesetih let.
Preizkušeno, bil sem prijetno presenečen nad toplim zvokom.
Škoda, da današnja mladina tega sploh ne pozna.

TUNER C440
8 Character preset naming capability • Easy & straightforward to use
• 30 Station random presets (AM or FM) in 3 banks
• 25 kHz tuning steps • NAD Blend • VFL display
• MOS-FET RF section and Front-End • NAD-Link for remote control capability
Tuners tend to be swamped with buttons nowadays, obliterating ease-ofuse. With the NAD Model C 440 get the intuitive, simple operation that
tuners used to offer but combined with the convenience of modern day
technology. Apart from convenience, the C 440 also offers the excellent
performance NAD tuners are acclaimed for.
Features
With 30 presets available you can store all your favorite radio stations.
These presets can be any combination of AM and FM stations: 25 presets
for FM and 5 for AM, or 17 for FM and 13 for AM, for instance. To avoid
having to scroll through 30 presets, the un-programmed (empty) ones are
skipped to give you quick access to all your favorite stations. You can
store the presets in any of the three different banks, labeled A, B or C.
This way you can organize the presets to suit personal preferences (for
example; his or hers or program type: rock, classical music, news, etc.).
When attempting to listen to weak stations, sometimes the background
noise can become annoying and spoil the listener's enjoyment of the
program. The BLEND function reduces this noise while still retaining
adequate stereo separation.
Instead of littering the front panel with buttons and features that are hardly
ever used, the NAD Model C 440 concentrates on convenience in daily
operation.
The C 440 will allow you to individually name each preset with up to
8 characters. Once you have named your presets you don't need to
remember which frequency goes with what radio station, the
name is indicated in the display every time the preset is recalled.
All the preset information is stored in the C 440's non-volatile memory,
which means it will remember all of its preset information even if the unit
has been unplugged for a prolonged amount of time.
Thanks to NAD-Link the Model C 440 can be remote controlled by one of
NAD's universal remote controls which come supplied with other NAD
equipment which sports NAD-Link.
Apart from ease-of-use, the NAD Model C 440 also offers features to get the
maximum out of the airwaves. Auto Search automatically stops at the next
strong radio signal it comes across and optimizes tuning. Weaker radio
stations can be tuned into manually.
Design
The MOS-FET RF section and Front End design together with high quality
components and careful PCB lay-out guarantees excellent sensitivity with
low intermodulation distortion to provide noise-free reception. Although
AM can never reach the quality of any FM transmission, the Model C 440's
AM section retains excellent clarity together with low background noise.
The Model C 440 offers performance, simplicity and value that NAD is so
renowned for.

NAD ENGLAND CD C 540
The DAC inside is a Burr Brown PCM1716E , 24 bits, 96KHz
Quote from the data sheet : The PCM1716 is designed for Mid to High grade Digital Audio applications which achieve 96kHz sampling rates with 24-bit audio data. PCM1716 uses a newly developed, enhanced multi-level delta-sigma modulator architecture that improves audio dynamic performance and reduces jitter sensitivity in actual applications.
The NAD did aproach a very interesting implementation.

NAD 317
Stereo Integrated Amplifier
The model 317 integrated amplifier uses an identical power amplifier circuit to the 214 power amplifier.
The unit has 6 line inputs, including 2 tape in/outputs with dubbing facilities.
By removing the links between the pre-out and main-in sockets the pre-amplifier section can be separated from the power amplifier for easy upgrades.
