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.

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
NAD has introduced some of the most innovative amplifier technology in its nearly 50-year history, starting with the 3020 on through such cutting edge models as the 2200, the 208, and the M2. Now they are making the amazing new Eigentakt™ (self-clocking) technology, recently introduced to the world in the EISA Award-winning Masters M33, available to a wider audience with the very affordable C 298. The perfect companion for the C 658 BluOS Streaming DAC preamplifier.
Getting the Basics Right
NAD's line inputs, both Balanced and Single-ended, can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device. These are all details you can hear.
Sophisticated Power
Nad has developed better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principles. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models. The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression. It can operate with any AC mains voltage from 100V to 240V and provides pure DC power to all the various stages of the C 298. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.
Purifi ‘Eigentakt’ Amplifier Technology
Purifi is a Danish technology company that has brought together several of the industry’s leading engineers to apply advanced mathematical modeling to solve the last remaining limitations of audio amplifiers. While there are many good sounding amplifiers on the market today, Purifi has taken a fresh look at every aspect of amplifier performance and found many seemingly small non-linearities that can make a dramatic difference in the overall sound. This return to first principles has resulted in a stunningly simple approach to some remarkably complex problems. With features and technology unmatched by other amplifiers in its class, the C 298 amplifier is an easy upgrade for any system and a surprising partner for the most sophisticated and advanced loudspeakers on the market. The Eigentakt modules are manufactured by NAD under license from Purifi, allowing NAD to optimize these specifically in combination with the custom-designed power supply and input stages of the C 298.
