Rerouting and Address Changes
We cannot make ANY address changes once an order is placed. If you are unable to accept delivery of your package as ordered, we will need to cancel your order, return the package to sender and have you replace your order through our website.
Keep the Box
We suggest you keep the shipping box or boxes for at least 30 days. It is actually a great idea to keep boxes for audio products for the life of the product. Having the box and all packing will increase the trade-in value should you decide to move up and they are handy to have should you ever need to send the unit in for repair.
How To Receive a Motor Freight Order
The trucking company will contact you to schedule a convenient time to deliver the order. Please note that you must be present for delivery.
Visually inspect the box to make sure you see no signs of damage. If you notice any damage at all, take some pictures with your phone and make a note of them on the delivery receipt the driver will ask you to sign. If it is obvious that the product is damaged, please refuse the order and contact us immediately at 888.899.8776 or email support@audioadvice.com.
Open your box as soon as possible and inspect the product for damage and contact us if you find anything wrong.
uShip In-Home Delivery
Due to current concerns surrounding COVID-19, uShip is able to offer THRESHOLD SERVICE ONLY at this time. To ensure everyone’s safety, uShip is advising carriers to refrain from making room-of-choice deliveries. Threshold service consists of the shipment being brought into the first door of the address or the lobby of an apartment/condo, and does not include set-up, installation, assembly or debris removal.
What to Expect: Most oversized items will be delivered within 2-3 weeks. Your carrier will place your item inside the first door of the address or the lobby of an apartment/condo.
Appointment Scheduling: Your delivery partner will call 24-48 hours prior to delivery to arrange an appointment window.
How to prepare for in-home delivery:
- Determine the clearest path from the street to your home
- Measure entrances and hallways to ensure your item will fit
- Remove any wall hangings or clutter to ensure a clear path and to prevent damages
- Remove old furnishings to allow placement for your new piece
Check your furniture for damages: We rarely expect damaged furniture, but in the instance it does happen, we have you covered. Once your item’s packaging is removed, check for any damages that may have occurred in transit. Take pictures of any damages and notate appropriately on the delivery receipt. Keep possession of the damaged piece and contact us via phone or email and we’ll start the process to repair/replace your new piece of furniture. For uShip customer support, please call 800-698-7447.
At Audio Advice, we pride ourselves on customer satisfaction. We'll bend over backward to make sure you're 100% satisfied and we won't accept anything less. We offer 30-day hassle-free returns and personalized service from real, live people.
If an item doesn't meet your expectations, you may return or exchange it in its original condition and packaging within 30 days for a full refund, minus shipping fees. Items shipped back in like new condition through standard shipping carriers will only incur a flat fee of $15 to return. If the items were initially shipped through free scheduled delivery via motor freight (commonly referred to as LTL), returning them will result in return shipping fees starting at $150. These items include but are not limited to, oversized items such as TVs, certain subwoofers, floorstanding speakers, furniture, and most items weighing over 75 pounds. Return fees will also apply for exchanges. We want to treat your system as if it is our own and want you to be completely satisfied with your purchase.
Please see the instructions below. We only accept returns for any product purchased directly from our website. If merchandise is not returned in its original condition or is missing packaging, manuals, accessories or other parts, or the resale value of the product has been impaired, a partial refund will be given and calculated on a case-by-case basis.
Non-Returnable Items
The following items cannot be returned or cancelled:
- Special/Custom Order Items
- Open Box Products
- Gift Cards
- In-ear headphones cannot be returned once the packaging has been opened due to personal hygiene reasons. Please contact our customer care team if you'd like help choosing.
-
Turntables With a Broken Stylus: All turntables ship out with the stylus intact. If you return a turntable or phono cartridge with a broken or missing stylus you will be subject to a return fee. Please be careful when setting up your turntable and contact us with any questions.
Is It Easy To Return An Item?
Yes, simply give us a call at 888.899.8776 or you can email our support team at support@audioadvice.com. Many times our team of experts can help figure out why the product might not be working like you expected and get things fixed over the phone, so don’t be surprised if we ask a few questions, we love troubleshooting!
If our tech help can not make you happy, we will email over a return shipping label with a Return Number.
Hopefully, you saved all of the original item’s box and packaging inserts. You will want to pack back up your return or exchange in the same way it came out of the original box. Once you have everything packaged correctly, tape the box on the top and bottom to assure it stays together. If Audio Advice shipped the item to you inside a second box, it's a good idea to use that same extra box to help prevent damage on its way back to us. To avoid it accidentally coming back to you, use a magic marker to cross out the old shipping label or just tear it off.
The return shipping label we send you will have our address on it, just make sure you take the box to the right shipper (UPS, FEDEX, or USPS) as per the label.
If you are close to one of our stores, please let us know if it is more convenient for you to return it to us directly. You will still need to get a return number by contacting us and shipping and/or restocking charges may apply.
When Will I See My Refund?
It usually takes around 7-14 days for the refund to show up on the payment method you used. We do inspect all returns for damage and accuracy of the item inside the box before issuing a refund. Some items may be subject to shipping and restocking fees.
Can I Exchange My Purchase For Something Different?
Sometimes those big speakers just don’t fit in the room or you might have bought a small subwoofer and later found out you’d love a bigger one. If you would like to make an exchange within 30 days of receiving your item, just give us a call at 888.899.8776 or email support@audioadvice.com and we will help work out the details. Additional shipping charges and return costs may apply.
How Do I Cancel An Order?
If the item has already shipped out or is a special order item, it is not possible to cancel the order. Please contact us at 888.899.8776 or email support@audioadvice.com to start the return process.
What If I Find Shipping Damage?
We need to know right away about any shipping damage. Please contact us at 888.899.8776 or email support@audioadvice.com within 48 hours of your delivery so we can get the ball rolling on making things right. It’s very helpful to take some pictures and email them to us if possible.
Can I Refuse A Shipment?
You can, but unless the item is damaged, shipping and restocking fees will be deducted from your refund. If your item arrives damaged and you are lucky enough to be there, snap some quick pics and refuse the order. Then contact us so we can get a replacement on the way.
What Happens If My Order Is Defective?
This is actually pretty rare, most consumer electronics work fine out of the box 99.9% of the time. We’d like for you to contact us first by calling 888.899.8776 or email support@audioadvice.com so we can help get to the bottom of things. If your item is indeed defective during the first 30 days, we can usually exchange it for a new, replacement unit.
What About Service After 30 Days?
Audio Advice has a great relationship with all of our brands and can help you with warranty service by the brand after our 30-day guarantee period. Even after the warranty expires, we can arrange for service by the brand on products purchased from Audio Advice. Just call 888.899.8776 or email support@audioadvice.com.
How Do You Determine A Restocking Fee?
You may not believe it, but sometimes we receive items back that were put in the box with zero packaging and are completely destroyed or are missing many of the pieces that came with the item. We also track serial numbers and will get back different serial numbers. We’ve even seen different items than what we shipped out be returned. However, it’s very important to package your return properly so that nothing goes missing or gets damaged in shipping, which will result in a restocking fee or even no refund at all. If a product is opened and the market value of the product is reduced, then a restocking fee may be applied to the cost of restocking and the reduced market value of the product. The bottom line is if you treat us fairly, we will do the same.
Audio Advice strives to provide industry-leading support and service while also maintaining the lowest prices available on products for our customers. We work hard with our vendors to bring our customers the best products at each price point. As a part of that process, we work with our vendors to provide the lowest pricing in our stores and on our website.
Our prices should always be the same as any other authorized dealer, including big-box retailers and major online retailers.
If you believe that you have found a lower advertised price from a legitimate authorized seller, call us and let us know so we can make sure we can correct any inadvertent error on our side. As a matter of policy, we update our prices automatically if a vendor changes its authorized pricing policies, so we generally have the best prices all the time. Increasingly, there are knock-off copies of products online, usually sold by non-authorized dealers.
Please be sure that the item meets the following conditions:
- The item is brand new, in stock, and available for purchase
- The item has the identical model number, color, etc as the item on our site.
- The seller is an authorized dealer
As always, our goal is to provide a terrific customer experience, including industry low prices. We appreciate your support.
Overview
The Bar has been Raised with the Masters M33 BluOS Streaming DAC Amplifier
NAD's 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 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 optimizes the impulse response. By optimizing the speaker/room interface, music sounds more natural and lifelike. Supplied with the 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.
Flexibility Meets Long-Term Value
In its standard form, the 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 analog 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.
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 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 color LCD 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 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.
