Introducing the Model 100

NSMT Model 100

Incredible resolution, imaging, soundstaging, and bass response

We are excited to announce the availability of our new Model 100 loudspeakers. Those of you who have followed NSMT Loudspeakers closely will notice some similarity to the Model 100M loudspeaker that was offered in our Mastering Series. In fact, the Model 100 is inspired by the design of the Model 100M. The Model 100M is now discontinued as its performance is surpassed by the new Model 100 which is now offered in our performance series of positive polarity loudspeakers.

Our approach to designing the Model 100 was to design a no-compromise, high resolution, musical loudspeaker that checks off nearly every box in the holy grail of loudspeaker performance. As a result, the Model 100 is a time coherent, minimum phase, positive polarity, hybrid design combining a two way acoustic suspension monitor section with a bandpass subwoofer section that is informed by the design of our highly acclaimed 15 EXP subwoofer.

The Model 100 features a 1 &1/8 inch hand coated textile dome tweeter, an 8 inch broad band woven carbon fiber driver and a 10 inch paper cone subwoofer. The tweeter is positioned where it is perfectly timed aligned with the carbon woofer driver. The bandpass subwoofer is vented to the front of the cabinet for seamless integration.

Cutting-edge resolution, imaging, soundstaging, and bass response

What makes the 100M resolution exceptional and its performance electrifying is that the broad band carbon fiber driver is crossover-less and covers the fundamental frequency range of  most instruments and voices from 35 Hz to 4,750 Hz. Only the pipe organ has fundamental frequencies above this range. There are no crossover induced phase or frequency abnormalities to muck up the sound in the fundamental frequencies range. The tweeter covers the harmonics of instruments and voices from 4,7500 Hz to 20,000 Hz. The tweeter's output is seamlessly integrated with the carbon fiber driver's  with a 6 dB slope. The subwoofer provides low bass reinforcement from 20 Hz to 200 Hz. All three drivers are wired in positive polarity to preserve the waveform of the original music source.

The Model 100 is a melding of our extensive experience building two-way loudspeakers and bandpass subwoofers. It has the magical imaging, resolution, soundstaging that only the best time coherent, minimum phase, positive polarity, two-way acoustic suspension loudspeaker can achieve. Combined with the articulate, dynamic performance of our 15EXP subwoofer, the Model 100's performance is hard too beat.

The Model 100 is available as passive speakers or with active subwoofers. The passive version costs $8,995 per pair. The active version of each speaker has a 200 watt RMS amplified subwoofer with adjustable crossover, volume, and phase controls. A pair of active Model 100 costs $9,995.

Finishes
The standard finish for the Model 100 is satin black top and bottom panels with black cloth applied as a veneer. The deluxe finish is satin black with red birch side panels. Because we manufacture our own cabinets we can offer the Model 100 with a custom finish of your choice.

The Model 100 is made to order with a delivery time of two to three weeks.

Listening to the NSMT Lepai amplifier with Bluetooth

NSMT Modified Lepai Amp with BluetoothBluetooth

"Bluetooth is implemented very nicely." Customer comment

 Buy NSMT-Lepai Amp

There is a lot of debate about the audiophile quality of music using a Bluetooth connection, but no dispute about Bluetooth's convenience.

Our solomonic solution is to add a Bluetooth option to our modified Lepai amplifier as a toggled on feature that is activated by a toggle switch on the back of the amplifier, so that with Bluetooth toggled off, the amplifier's performance is unaffected. Moreover, we will continue to offer the amplifier without the Bluetooth option.

All Bluetooth receivers are not created equal. Some are indeed quite harsh. The Bluetooth feature we have added to our Modified Lepai amplifier is one of the best available.

I have spent the last few weeks putting our Modified Lepai amplifier with optional Bluetooth through the paces and I can assure you that the listening experience is quite pleasant and very rewarding.

I listened to our Modified Lepai  amp with Bluetooth driving either a pair of Role Audio Sampan or Sampan FTL loudspeakers connected to our modified Lepai via an eight foot pair of our MasterSource speaker cables.

For source I mostly used a Moto X smart phone connected to the amp via Bluetooth and compared that to a FiiO X3 connected via the line out to the RCA jacks of the Modified  Lepai. The music I used was WAV files copied from CDs.

The Sampans were set up against one long wall with the Lepai sitting on a table slightly behind them. The Sampan FTLs were set up on the same table as our modified Lepai amplifier. Most of the time I was working at my desk about six feet from, and a little in front of, the leftmost Sampan, and listening to music played on the Moto X's stock Android music player connected to our modified Lepai via Bluetooth.

I found it convenient to set the volume knob on the Modified Lepai at about 1 O'clock. Then I was able to adjust the volume up or down via the Moto X. The ease and flexibility of the Android music player interface is simply amazing. If my phone rang I didn't have to run over and turn down my music in order to answer the phone. The Moto X muted the phone automatically. Also the phone notified me bad weather, calls, tweets, etc. which I could attend to or ignore. To approach this level of control playing background music through the typical stereo while I am working I would have had to use a remote for volume and one for source. My Moto X does all that and more.

For critical evaluation I sat on a couch about six feet in front of the speakers to mitigate some of the faults of the room.

So how does music played via the Moto X connect to the Modified Lepai via Bluetooth sound and how does it compare to music played on the FiiO X3 connected to our Modified Lepai via RCA jacks?

The sound of the Moto X connected to our Modified Lepai amp via Bluetooth is very pleasant. In my notes I used such adjectives as analog, smooth, laid back, slightly muted highs, like FM radio, and musical.

How does the Moto X source compare to the Fii0 X3? At low volume, say up to 85 dBs, I struggled to characterize the differences.

Note for comparable volume level I had to set the Lepai volume control to 9 O'clock when listening to the Fii0, compared to the roughly 1 O'clock setting for the Moto X. The Fii0's output volume is that much higher.

The Lepai benefits from a high input volume but on some albums that are recorded at a very high level such as Sade's “Solder of Love,” The Fii0's output overloaded the Lepai causing distortion. In such cases I had to switch to using the Fii0's headphone jack and volume control.*

As the volume went up though the differences between the two sources became more obvious. The Fii0 resolves more information, the delineation of the bass and the bass weight is better, definition across the board is better, the sound stage is a little deeper and the layering is more delineated.  I listened to Luther Vandross' Superstar, a song I have used as a reference for decades. At low to moderate levels I had to concentrate to discern differences between music sourced via the Moto X and Bluetooth vs music sourced from the Fii0 X3. All the spatial cues are present is both cases but the delineation and clarity are superior on the Fii0 X3.

One thing for sure, the benefits and ease of using the smartphone interface are obvious compared to the Fii0 X3's interface which is challenging and not very flexible.

In sum the audiophile differences between music sourced from my Moto X via Bluetooth and music sourced from the Fii0 X3 are clear. However for ease and convenience listening to background music the Moto X Bluetooth combination trumps listening to music sourced from the Fii0 X3. And while the Fii0 X3 has better resolution. At low to moderate listening levels those differences are not very obvious.

So what did I find out aver a few weeks of listening. Bluetooth provides an ease and flexibility for listening to music that is unmatched. Sure there are dropout that can occur at almost any distance but this is easily cured by repositioning the smartphone and maintaining a direct line of sight between Bluetooth transceiver and amplifier. But again, the facility it presents for listening to music is unparalleled.

My overall take on Bluetooth is that it is is not perfect but it allows me to listen to more music on the go and while working, simply because of its convenience and because I am willing to compromise on quality for the ease of listening.

My goal in adding the Bluetooth feature to our modified Lepai amp is to extent the uses for the amplifier and to make it easier for you to listen to music reproduced with the best possible fidelity.

Regardless of where you stand on the purist vs convenience divide you will find satisfaction with either our Modified Lepai amplifier of the amplifier with the Bluetooth option.

Happy listening.

ER.

* The X3  has  a line output designed to feed a hi-fi amplifier through a 3.5mm jack that delivers a fixed 1.7V maximum. The Fii0 delivers .3V  through the headphone socket which is 50% more output than most CD players, and many times the output of most portable music players. Hence, the Fii0 provides about 10dB more dynamic range than CDs.
