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
As the new flagship of NAD’s Classic series of integrated amps, the C 399 HybridDigital DAC Amplifier takes NAD’s commitment to lasting value and sonic excellence to a whole new level. The C 399 employs NAD’s Hypex HybridDigital nCore amplifier circuitry, which until now has been available only on Masters Series amplifiers. Its digital section is built around a 32-bit/384kHz ESS Sabre DAC, the same chip used in NAD’s acclaimed M10 and M33 Masters Series amplifiers. The C 399 is the first amplifier to incorporate the latest generation of NAD’s Modular Design Construction (MDC) technology. MDC2 lets users add optional modules that provide functions such as BluOS multi-room music streaming and Dirac Live room correction.
Perfect Power
Trickled down from NAD’s Masters Series, the C 399’s HybridDigital nCore amplifier can deliver 180 Watts per channel continuous power, and 250 Watts per channel instantaneous power. Highly efficient and remarkably powerful, the HybridDigital nCore amplifier can produce musical transients effortlessly. The design is renowned for its wide bandwidth, flat frequency response, clean clipping behaviour with instant recovery, high current capability, and stability into demanding low-impedance speaker loads. Noise and distortion are vanishingly low under all operating conditions. The minute levels of harmonic distortion are dominated by sonically benign second and third harmonics. The Hypex nCore design enables the C 399 to produce neutral, distortion-free sound even at very high listening levels, with exquisite detail, superb portrayal of space, and thrilling dynamics. Also trickled down from the Masters Series is the ESS Sabre 9028 high-resolution DAC, a design noted for near-zero levels of clock jitter, ultra-low noise and distortion, and wide dynamic range. This premium DAC enables the C 399 to reproduce all your digital sources with amazing musicality, stunning clarity, and precise soundstaging.
Future Proof
In 2007, NAD introduced Modular Design Construction, an innovative architecture for adding new functions to existing components. Many NAD products have rear-panel slots for MDC modules that perform HDMI switching, BluOS multi-room music streaming, Dolby Atmos surround processing, and other functions. The C 399 is the first product to feature NAD’s new MDC2 architecture. By enabling two-way communications between the module and component, MDC2 opens up the future for new upgrades. Equipped with Wi-Fi and Ethernet, the optional MDC2 BluOS-D module lets listeners play music from their favourite streaming services through the C 399, using the acclaimed BluOS Controller app for Android, iOS, macOS, and Windows. Like all BluOS-enabled products, the MDC2 BluOS-D has integrated support for dozens of streaming services; and supports Apple AirPlay 2, Spotify Connect, and Tidal Connect. Two-way communications also enable the MDC2 BluOS-D to stream music from sources connected to the C 399 to BluOS-enabled components in other rooms. The Dirac Live function lets you measure your room’s acoustics using a supplied microphone and intuitive app, and then upload correction curves to the MDC2 BluOS-D. By compensating for acoustic anomalies in your listening environment, Dirac Live dramatically improves bass clarity, imaging, and timbral accuracy. Thanks to its two-way architecture, the MDC2 BluOS-D performs room correction for all sources connected to your C 399.
Everything's Connected
The C 399 can accommodate all your digital and analogue sources. Its MM phono stage delivers ultra-precise RIAA equalization, extremely low noise, and high overload margins. The phono preamp also features an innovative circuit that suppresses the infrasonic noise present on all LPs, without compromising bass response. There are two sets of line-level line inputs, with low-noise buffer amplifiers to prevent sonic degradation. The C 399 has two optical and two coaxial digital inputs, plus an HDMI-eARC port for playing audio from a connected TV, while controlling amplifier output with the TV’s remote control. In addition to two sets of speaker outputs, the C 399 has preamp output jacks and dual subwoofer outputs. Two-way apt-X HD Bluetooth allows 24-bit streaming from mobile devices, and high-quality output to Bluetooth headphones. Also built-in is a dedicated headphone amplifier with low output impedance and high output voltage capability, enabling the C 399 to drive demanding high-impedance studio monitor headphones.
A Timeless Classic
As with every NAD amplifier ever made, the C 399 gets the basics right: a precise volume control with accurate channel balance, low-noise circuits, and correct input and output impedances. But it goes far beyond the basics. With its HybridDigital nCore output stage and high-resolution ESS Sabre DAC, the C 399 can reproduce all your digital and analogue sources with a level of excitement and refinement that is unprecedented for a Classic-series integrated amplifier. Thanks to NAD’s innovative MDC2 platform, the C 399 will keep pace with future developments. Essentially, MDC2 makes obsolescence obsolete. The C 399 can serve as the hub of a world-class music system today, and for years to come. With NAD’s C 399 HybridDigital DAC Amplifier, the legend continues.
