NAD M33 BluOS Streaming DAC Amplifier Award Image

The NAD M33 BluOS™ enabled DAC/amplifier is an ultra-high-performance streaming amplifier with superb audiophile sound. As a BluOS enabled component, the M33 can be combined with other players in a BluOS ecosystem of wirelessly networked music players throughout the home for an outstanding whole-home audio system. With the employment of the new Purifi Eigentakt™ Hybrid Digital amplifier technology, the M33 follows NAD’s long-standing tradition in identifying and developing cutting-edge amplification technology. With a minimum of 200W per channel on tap, the result is lifelike performance, exemplified by ultra-low distortion and noise.

Our Flagship Model Builds On Remarkable Success with Advanced Features, Cutting-Edge Technology and High Power

Part of a growing ecosystem of compatible products, BluOS tightly integrates hardware and software for an exceptional user experience. The only true wireless High-Resolution multi-room system available today, BluOS supports the new standard for High Res streaming, Master Quality Authenticated (MQA). BluOS also supports over 20 free and paid subscription services as well as supporting locally stored music libraries. With BluOS, the M33 retains all the audiophile features and further adds a range of facilities that will expand its capabilities yet simplifies ease-of-use at the same time. Operable with the BluOS app, the supplied remote control or through hands-free control with any Amazon Alexa or Google Assistant device, the M33’s front panel never needs to be touched.

DIRAC Live Room Correction On Board

Experts agree that room acoustics are the weakest link in most sound systems with room reflections deteriorating tonal balance and dynamics. Dirac, one of the most highly regarded Room Correction systems available, not only adjusts for frequency response, but unlike other room correction systems, it also optimises the impulse response. By optimizing the speaker/room interface, music sounds more natural and lifelike. Supplied with the NAD M33 is a precision microphone to measure the room at and around the listening position so your system can be precisely calibrated for optimum performance. Even the most sophisticated loudspeakers can be markedly improved using Dirac calibration. Each of the 5 Dirac memory slots can store a unique room measurement or different frequency target curves to suit a particular musical taste or genre. The M33 also supports Dirac’s advanced ‘Bass Control’* feature with two independent subwoofer outputs.

Flexibility Meets Long-Term Value

NAD M33 is very complete with a wide range of in/outputs, BluOS, Dirac, HDMI and more already fully integrated. It will meet the requirements of the most demanding users. To minimize the risk of future obsolescence, the M33 comes with two MDC (Modular Design Construction) slots that allow for further expansion. NAD introduced the MDC platform well over a decade ago and allowed updating products with new technologies which didn’t even exist at time of introduction

Connection and Wireless Flexibility

Whether looking to connect digital or analogue sources, the M33 comes well equipped to accommodate for all of these: 6 digital inputs and 3 analogue inputs, including MM phono. Around back, the rear panel hosts two sets of speaker outputs capable of bi-wiring and a stereo Subwoofer Output with a fully configurable Digital Crossover. Airplay 2 and Bluetooth AptX-HD allow for local wireless streaming from a phone or tablet.

*Some features will be available via a future software update

Phono and Headphones Are Not Forgotten

The M33 has a high-quality MM Phono Input that rivals specialized outboard units. Accurate RIAA equalization, a clever phase cancelling infrasonic filter, and a huge overload margin combine to bring out the best in LPs. Furthermore, headphone enthusiasts will delight at the sound of the discrete headphone amplifier, which is able to drive even planar and high impedance studio phones. With high voltage and low output impedance, headphones will sound their best. For those who wish to enjoy their headphones but not be tethered to a cable, the integrated Bluetooth AptX-HD module makes it simple to possible to enjoy wireless headphones as well.

Attractive Design With Outstanding Ergonomics

The all alloy casework is elegant yet practical. The single control knob for volume is supplemented by a colour TFT touchscreen display. Rigid panels with magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction. The M33 employs a completely modern and fresh take on the traditional stereo amplifier, with features and performance from the future.

Smart Home Integration Made Easy

BluOS provides hands-free control with full integration of any Amazon Alexa or Google Assistant device. Through Airplay 2, control is also possible with Siri. Considerable effort has been spent to make the M33 fully compatible with all the leading smart home systems from leading companies like Apple, Crestron, Control4, Lutron, KNX and many others. This means that along with lighting, shades, HVAC, and security, the integrator or user can seamlessly control the BluOS multi-room music system from a common interface. All integrations are certified for reliable operation. The custom BluOS Apps for iOS and Android tablets and phones, as well as desktop control from Windows and Apple OS are available free-of-charge and are updated regularly.

Klipsch Forte IV 3-way 12” Horn-loaded Loudspeaker – Pair – American Black

High Performance Is Our Forte

First introduced in 1985, the Klipsch Forte IV quickly established itself as the most popular Klipsch model. The elegant design and outstanding performance made the Forte a standout among its competitors. In 2017, Klipsch re-introduced the Forte as part of the Heritage speaker series. The new Forte IV features updated cosmetics and the latest advancements in acoustic engineering, while maintaining the original charisma that made the Forte so popular.

Designed And Made In The USA

Don’t mess with perfection. We’ve made some important upgrades to the Klipsch Forte IV, but it remains relatively unchanged since its inception. Remember great sound? We do, too. The Forte IV enclosure is still made in the USA, by proud craftsmen in Hope, Arkansas. Just like Paul W. Klipsch (PWK) intended.

High Efficiency, High Performance Loudspeaker

The Klipsch Forte IV hosts a three-way design utilizing a 12” woofer and horn-loaded midrange and tweeter. The Forte IV incorporates an all new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702 midrange is mated to a modified Tractrix® horn — featuring our patented Mumps technology for even polar response of mid frequencies, giving you more consistent sound throughout the listening area. The titanium diaphragm high-frequency driver has an all-new wide dispersion phase plug for providing exceptionally even high-frequency dispersion for a wider, more accurate sweet spot.

Passive Radiator Yields Full Range Performance

The Klipsch Forte IV’s well-extended bass is found in the use of a rear-mounted passive radiator. A mammoth 15” (38 cm) in size, this sub-bass radiator operates on acoustic pressure generated by the active woofer for greater bass output and extension.


The Forte IV has been completely revoiced from its predecessor, utilizing premium componentry in an all new high-fidelity network — minimizing electrical degradation throughout the circuitry — for truer to life sound with best in class efficiency and power handling. The new network draws from the classic three-way steep slope design of the legendary Klipschorn and La Scala speakers.

Bi-amp Input Panel And Binding Posts

The Forte’s premium, aluminum input panel accommodates large, high-quality speaker cables. Strong, versatile and quality binding posts provide the capability for bi-wiring or bi-amping.

Book-matched Wood Veneer

Klipsch only uses book-matched wood veneers for the Heritage series. The veneer leaves are kept in order as they are delicately sliced from the timber and precisely arranged to provide a mirror image at the splice joint — like turning the pages of a book. This gives each speaker an aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.

Matched Pairs

Every pair of Heritage series loudspeakers are grain-matched using wood veneer panels that come from the same timber. Each cabinet is carefully matched so that each speaker in the pair is practically indistinguishable from the other. The speakers move seamlessly together through the factory, and each finished product is inspected and labeled with sequential serial numbers, ensuring that your Heritage series speakers leave the factory as a meticulously crafted set.

Built to Last

While each and every component of the Forte IV is built to last, Klipsch has always recognized the unique and critical role of a loudspeaker’s cabinet in the sound reproduction process. From the craftsmen in Hope, AR to the engineers in Indianapolis, IN, Klipsch has always put an extraordinary emphasis on cabinet design. The Forte enclosure is assembled using only the highest-grade adhesives and fasteners. This is a speaker you will hand down from generation to generation.
