Κανένα αίσθημα δεν πρέπει να σου δημιουργείται Θέμη μου.Απλά όπως είπα και πιο πάνω
θα ήθελα να βοηθήσετε όλοι να διατηρηθεί ο αρχικός χαρακτήρας του νήματος
χωρίς να χρειάζονται δυσάρεστες επεμβάσεις από την μεριά της διαχείρησης.

Οταν πχ στέλνει κάποιος αντιπρόσωπος ένα Δελτίο Τύπου σε ένα περιοδικό φροντίζει να είναι πλήρες στοιχείων
και δεν επανέρχεται κάνοντας διάλογο με τους αναγνώστες.

Θα μπορούσες κατά την γνώμη μου να περιμένεις λίγο μέχρι να έχεις πλήρη στοιχεία για το προιόν.

Νεοι NAIT 5si, NAIT XS 2 και SUPERNAIT 2

Νεοι NAIT 5si, NAIT XS 2 και SUPERNAIT 2:

On sale next month is a complete new range of Naim NAIT integrated amplifiers: the NAIT 5si, NAIT XS 2 and SUPERNAIT 2. The three models have been designed with improved power supplies, better components in critical areas, new circuit layouts and built-in headphone amplifiers.

Launching the new amplifiers in Salisbury yesterday, Naim MD Paul Stephenson explained that in recent years the company has been concentrating on the development of its wide range of streaming products.

With those established, and attracting new buyers to the brand, he said, now it was taking the opportunity to look inward at the products already in its portfolio – in this case its line-up of integrated amplifiers.

The new products mark a simpler, even more performance-oriented approach, most notable in the SUPERNAIT 2 , which has lost the digital inputs and separate record/listen selector buttons of the current model.

Instead, all three new models have a common look, increasing in size as you move up the range.

Naim NAIT 5si


Naim NAIT 5si
The entry-level model, the £925 NAIT 5si (above), uses a passive preamplifier stage combined with a 60W per channel high-gain power section, up from the 50W of the model it replaces due to the use of a larger transformer and improved power supply.

Naim NAIT 5si

That output is quoted into 8ohms, the amp being able to deliver 90W into 4ohm loads.
Components have been upgraded in critical areas such as the power amp stage, and all signal capacitors changed to high-quality film types, while the main circuitboard and wiring loom have been improved using experience gained on products such as the DAC-V1.

Naim NAIT 5si

The toroidal transformer has separate windings for the amplifier and its control electronics, and the amplifier has four analogue inputs – two on Naim's familiar locking DIN sockets, and two on RCA phonos – and a 6.35mm headphone socket. It uses an aluminium chassis and sleeve, with a zinc die-cast fascia.


Naim NAIT XS 2

Naim NAIT XS 2

The NAIT XS 2, which will sell for £1595, again has a power hike over the current XS thanks to a larger transformer: it will deliver 70Wpc into 8ohms and 100W into 4ohms. It has six analogue inputs – four on both RCAs and DIN, one on a choice or RCA or 3.5mm stereo jack, and one powered DIN input for use with the company's StageLine or SuperLine phono stages.

Naim NAIT XS 2

A high-quality dedicated Class A headphone amplifier is also fitted in place of the simpler amp used in the NAIT 5si, there's a USB-mini B socket for updates, power amp in and preamp out sockets allow future expansion, and the amp can also be upgraded with the use of Naim's FlatCap, HiCap or SuperCap power supplies to power its preamp section.

Naim NAIT XS 2

Constant current source circuit techniques are used to provide ultra-quiet drive signals for the switching relays, ceramic heatsink isolators are used to improve sound quality by enhancing heat dissipation, and again components have been upgraded in critical areas, along with the PCB and the wiring loom.

The custom transformer has seven secondary windings to feed the various sections of the amplifier, and the microprocessor controlling the amplifier has been designed to 'sleep' when it's not being used, thus improving sound quality, and then wake as soon as a command is received from the front-panel buttons or remote handset.

There's also an external remote input for use with Naim products offering system automation connectivity. This allows the amplifier to be 'driven', for example, by a Naim network music player using the n-Stream control app.

A simple rear-panel switch is also provided to engage unity-gain/AV passthrough on the NAIT XS 2's AV input, allowing the amplifier to be integrated with a home cinema receiver or processor with front channel preouts.

Naim SUPERNAIT 2

Naim SUPERNAIT 2

As already mentioned, the £2750 SUPERNAIT 2 is most notable for the removal of the digital section found on the current SUPERNAIT, Naim explaining that its SuperUniti already fulfils the role of integrated amplifier with digital input in its range, and that the ND series streamers with which the new amplifiers are likely to be used also have digital inputs.

As a result, the decision was taken to concentrate on improving the SUPERNAIT as an analogue amplifier, not least by allowing its power supplies to be further optimised for its analogue stages, rather than also having to run a DAC.

As with the current model, the SUPERNAIT 2 delivers 80W per channel (or 135Wpc into 4ohms) – its larger transformer, with seven secondary windings, is used to enhance the amplifier's dynamic abilities.

Naim SUPERNAIT 2

The power supply for the preamplifier stage uses Naim's DR (Direct Regulator) technology, also found in the company's latest offboard power supplies, and all inputs are hand-wired, and thus decoupled from the main circuitboard to improve microphonic isolation.

Again the SUPERNAIT 2 benefits from the upgrade of components, layout and wiring throughout, and like the NAIT XS 2 it has a dedicated Class A headphone amplifier, Naim's Electronic Design Manager, Steve Sells, explaining that the amplifier has been designed to drive an extremely wide range of headphone loads.

Naim SUPERNAIT 2

The SUPERUNITI 2 has the same input provision as the NAIT XS 2 – four on both RCAs and DIN, one on a choice or RCA or 3.5mm stereo jack, and one powered DIN input for use with the company's phono stages –, and also has record and subwoofer outputs, a USB-mini B socket for updates, and the remote input and AV bypass switching also seen on the NAIT XS 2.


Design notes
The new amps have been designed using the tools and experience the company has been developing and using during the past ten years' development of projects such as the Uniti and ND streaming ranges, and the Naim for Bentley in-car systems.

As Technical Director Roy George explained, in that time the company has made increasing use of computer tools for electronic simulation, enabling circuits to be designed and tested virtually, and CAD systems for purposes such as thermal analysis of designs, enabling whole products to be modelled and tested on the computers.

George says that not only does this save time, it also improves creativity, with developers now able to try things in this virtual modelling world that they would never do if they had to build and test real circuits in order to examine their performance and behaviour

He adds that over the past decade, the R&D department at Naim has risen from to 31 people, with nine now entirely responsible for software development, and that the company has written some 1.4m lines of code in the development of its streaming products, and developed over 100 products in ten years.

Steve Sells with Naim SUPERUNITI 2Steve Sells, seen left with the SUPERUNITI 2, explains the thinking behind the new NAIT models as being all about removing superfluous components and features and concentrating on performance.

He describes the NAIT 5si as 'a stripped-back racer' of an amplifier, and says that even here the main elements of the design of the new models can be seen.

The transformer is kept well away from the inputs, to keep any electromagnetic interference clear of the delicate input signals, while the power supply and its capacitors are mounted close to both the transformer and the output devices.

Control circuits are optically isolated from signal sections, and everything is done to isolate sensitive components from external vibration, to the extent of mounting critical resistors above the main board, so that their 'legs' provide some damping.

Naim SUPERUNITI 2 volume control

The board itself is also mounted compliantly, as are the ALPS Blue Velvet potentiometers (above) used for used for volume and balance control, and of course the amplifiers all have Naim's usual 'wobbly' mains sockets and switches, to isolate the internal circuitry from any mechanical vibration picked up on the mains cables.

The new NAIT models will be in Naim dealers in the middle of July.

ATC LOUDSPEAKER TECHNOLOGY ANNOUNCES THE LAUNCH OF THE NEW ‛HI FI’ PASSIVE SERIES SCM 19 AND SCM 40 LOUDSPEAKERS

Designed for small to medium scale stereo and multi-channel applications, two new models incorporate a wholly ATC designed and built tweeter, and stylishly curved cabinets.
Featuring the new ATC designed and built 25mm soft dome tweeter, updated bass/mid drivers and crossovers housed in a curved, laminated cabinet, the first of a new range of ATC closed-box passive loudspeakers has arrived. The second generation SCM19 and second gen. SCM40 are the first to employ ATC’s landmark SH25-76 tweeter, developed to satisfy the company’s long-established rigour in drive unit engineering. The loudspeakers join the new SCM7 and SCM11 to complete the new ATC Hi-Fi Passive Series line up.

SH25-76 Tweeter
Sharing technology with the renowned ATC soft domed mid-range drive unit, the new tweeter employs a unique dual suspension system suppressing rocking modes even at high power output levels. The ATC configuration of a short edge-wound voice coil in a long, narrow magnetic gap ensures exceptionally low distortion throughout its operating band and removes the need for ferrofluids, which can dry out over time, compromising performance.
A complex, shaped, soft-domed diaphragm extends high frequency range and offers a smooth off-axis response. The tweeter’s 15,000 gauss (1.5 tesla) neodymium magnet has a black heat-treated top plate, which dissipates heat away from the voice coil to maintain high power handling and low power compression. A precision-machined 5.5mm rigid alloy waveguide provides optimum dispersion, a flat on-axis frequency response and resonance-free operation.

New Cabinets and Systems
Establishing what is to be a new style for ATC’s most competitively priced range of loudspeakers, and joining the new SCM7 and SCM11 launched earlier in the year, the new SCM19 and SCM40 benefit acoustically and aesthetically from a curved cabinet construction. Braced and laminated for high rigidity and damping, the curved enclosures in real cherry or black ash veneer also impart a strong impression of design quality. Improved crossovers featuring metallised polypropylene capacitors, large air cored inductors and ceramic wire-round resistors offer superior power handling and clarity. Each new model exhibits an impedance curve free from low values, presenting an easy load for amplifiers of 75
to 300 watts. The SCM19 and SCM40 are designed for optimum performance with the grill in place – although the difference in performance without the grill is minimal. The metal grille, finished in anthracite grey, fixes to the cabinet via hidden magnets. According to tradition, each model number represents internal cabinet volume in litres.

Second Generation SCM19
ATC’s SH25-76 soft dome tweeter is joined by the company’s highly linear 150mm mid/bass driver. It features an integrated 75mm soft dome - exceptional for its horizontal dispersion of mid-band frequencies - and a huge 9kg high- energy, ‛Super Linear’ magnet system, which includes a 75mm diameter flat wire, underhung voice coil, meticulously milled and formed by ATC. The magnet system and a carefully weighted doped fabric cone assembly contribute to the SCM19’s wide bandwidth, impressive dynamic range and convincing bass output coupled with very low distortion as a result of the unique ‛Super Linear’ motor system.

Second Generation SCM40
The new SCM40 features ATC’s new SH25-76 tweeter with a ATC’s renowned 75mm/3” Soft Dome mid-range and a 164mm, short coil – long gap (underhung) bass driver. The three-way design and inclusion of the Soft Dome mid results in excellent clarity, even at high drive levels with bass heavy souce material. It also gives wide, even dispersion resulting in excellent stereo imaging and un-fussy positioning in the home. The new model also benefits from crossover revisions that have improved the loudspeakers overall balance and the integration between mid and high frequency elements.
Manufactured in-house, the new SCM19 and SCM40 offer the ownership of a hand-built ruggedly engineered speaker, world famous for musical accuracy and high power output. Like all ATC products, the new models are backed by a six- year warranty.

Wild guess...
Το ηχοπερατό κάθεται στο ηχείο με μαγνήτες (δεν βλέπω τρύπες) και για αυτό δεν μπορούσαν να βάλουν τη μαύρη μπάφλα...
Αρχίζει να χάνει τη macho εμφάνιση όμως...

Και η μαύρη μπάφλα είναι ξύλινη. Δεν νομίζω ότι προσθέτει ιδιαίτερο κόστος.
Αυτό που βλέπω είναι ότι το woofer έχει βγει πιο έξω σε αντίθεση με mid και tweeter που έχουν μείνει στην ίδια θέση.
Και δεν νομίζω ότι είναι τυχαίο...

Από τη μια η ATC είναι η ATC και οι επιλογές της είναι απολύτως σεβαστές (αφου τις ακούσουμε κιόλας εννοείται) αλλά το "κοψιμο" της έξτρα μπάφλας -χαρακτηριστικό στοιχείο και των ακριβότερων σειρών της- δεν μπορεί να μην μου μοιάσει σαν επιλογή περιορισμού κόστους!
Επίσης με βάζει σε σκέψεις το εξης: με δεδομένο πως τα μεγάφωνα της εταιρίας είναι βαριά -πολύ βαριά- και μάλιστα στο πίσω μέρος τους λογω των τεράστιων μαγνητών.. μήπως η μη ύπαρξη εξτρα ενισχυμένης μπάφλας οδηγήσει μακροπρόθεσμα, με δεδομένο και το οτι τα ηχεία την ATC σηκώνουν τρελά γκάζια, σε "θέματα" στην καμπίνα; Εκτός αν η ενίσχυση είναι πλέον εσωτερική.... οπότε πάσο!!!!

Όπως και να έχει δεν βλέπω την ώρα να τα ακούσω!!!!
