Top-notch reception and convenient use

Listening to music, catching a ballgame, keeping up with the news.... There are several reasons why a strong AM/FM tuner can be a key addition to your home stereo system. The NAD C 427 tuner makes sure your radio stations come through clearly by using a low-distortion design and features such as "FM Mute," which eliminates inter-station tuning noises,.

With the C 427's 40 available presets and simple controls, you can store and scroll through your favorite radio stations with ease. The tuner's screen displays Radio Data System information, so you can see what station, artist, and song you're listening to (available with select FM stations). You can control it with the supplied remote, or integrate it with your existing external controller or universal remote. The NAD C 427 works well with NAD's highly-regarded integrated amplifiers.

Good sound and build quality, nice display, but preset access via rotary encoder isn't intuitive (at least to me), so 4 out of 5.

Crutchfield Customer Review (What's this?)

Nice tuner that picks up stations well and sounds good. I rated 4 stars because its lacking any type of signal strength meter. For this price I kinda expect that option. Its a keeper for now.

Pros: Picks up stations well

Cons: No signal strength meter

Crutchfield Customer Review (What's this?)

After a long period with AVRs' I decide to get back to the root for me pure stereo. This unit is well worth the money invested. Reception and clarity are solid. The simple clean look fits well between the amp and CD player. My girlfriend is new to true stero but she immediately appreciated the difference we she heard her favorite station.

Pros: Excellent reception and size.

Cons: None

Crutchfield Customer Review (What's this?)

This thing gets solid reception on distant FM channels.

Pros: Runs cool. Sounds good enough that my wife, who was upset that I bought it, stopped complaining the minute she heard her favorite station coming in better than she had ever heard it before.

Cons: Cost more than a pretty decent receiver.

One of the Best

Written by: Corgidog59 from Washington DC on January 13, 2016

Crutchfield Customer Review (What's this?)

I recently made big changes to my home theater/audio system. I decided to split it into two separate systems sharing the same rack. what this means is that my AVR (Yamaha RX-V1030) is now dedicated to home theater. Then I bought a 2 channel amp, pre-amp, separate L/R front speakers and now a tuner for my 2 channel system. Initially, I bought a tuner which cost nearly 4X that of the NAD 427 (and took nearly 6 weeks to arrive from Europe). I thought given the price that it would be one of the best on the market. I hooked up and attempted to do some critical but highly satisfying listening. Well, not so fast. The reception was extremely spotty. I would get a number of stations without a using antenna. When I tried to hook up a dipole antenna or rabbit ears, I got worse reception . My AVR got much better reception. Crazy I thought. Also, the unit came with no remote. If I wanted a remote, I would have to purchase one for about more $. So, I decided to see if the NAD 427 would perform better at 1/4 of the cost of the other one. The answer is a big YES! The NAD 427 Tuner is head and shoulders better.. The NAD 427 picked up all the stations that I was interested in with great reception/clarity. So, if you are in the market for a tuner (and oh by the way, there are fewer and fewer companies producing them now) by all means consider the NAD 427.

Pros: Great reception. Ease of use. Helpful display

Cons: Plastic remote.

Good product

Crutchfield Customer Review (What's this?)

Straight forward tuner with good reception on both AM and FM. Blend feature works! Plenty of presets. Display has a dimming option and is a good design. We are using this tuner where there are few local stations plus we have nearby mountains that can cause issues with stereo reception. Stations from miles away come in clear without a special antenna. Over the years I have accumulated a variety of other tuners from old 1930's radios, tubed Fisher, Harmon Kardon, Sherwood, and Sony receivers, etc. For reception this one rates very high when comparing. It is connected to a Rotel amp and sounds good!

Pros: Good performing off the air tuner. Controls are intuitive. Sound quality is good.

Cons: none

Crutchfield Customer Review (What's this?)

This tuner is only the second one I've had in my forty years as an amateur audiophile (my first was a Dynaco kit). I run the NAD through a Linn preamp, amp and speakers. The sound is clear, the controls easy to use.

Pros: See above.

Cons: An auxiliary AC outlet would be useful.

NAD C 427 Tuner

Written by: Dr. Rick from Oregon on November 16, 2015

Crutchfield Customer Review (What's this?)

The NAD tuner is a replacement for my old ADCOM GTP-500 ll which I've had for about 30 years (this is a preamp/tuner, it is the preamp that was failing). I was a bit anxious about finding an AM/FM tuner that was at least as good as the ADCOM. The worry was not warranted as the NAD tuner surpasses the ADCOM in every aspect: selectivity, sensitivity, muting between stations and channel separation. The controls are simple and while comprehensive, do not add unwanted and unnecessary functions. I also appreciate the understated overall appearance ( I am not a fan of multi-colored flashing LEDs that are just annoying ). The price is a bit higher than some inferior products, but since I maintain my equipment for years, the extra cost vs. value makes sense. Again, no need for anxiety.

Pros: Nad's known quality, overall tuner functionality and simplicity, clean understated appearance.

Cons: Other than the relatively higher cost, no complaints

NAD C 427 AM/FM tuner

Written by: Michael M from New York on October 6, 2015

Crutchfield Customer Review (What's this?)

This is the best tuner by far of the six I have owned. The design is attractive and straightforwardly functional; the only thing I miss is some sort of signal strength indicator, though this is not an issue. The signals come in clean and quiet. The wire antenna supplied with the unit is entirely adequate. My local stations come in loud and clear, of course, but even the stations in Toronto are adequately handled. I recommend this product without reservation.

Pros: Excellent reception, fine design.

Cons: None worth mentioning.

tuner with great reception

Written by: Bryan from Washington on September 17, 2015

Crutchfield Customer Review (What's this?)

Since I have had this tuner now for several weeks, it has grown on me for the way it performs well, locks in on a good multitude of stations, displays radio station data text from stations that enable this, and it is incredibly easy to use in the famous NAD fashion. I really like their uncluttered look on outside, great sound quality on the inside. Very happy with this tuner in my all audio only setup(NAD CD player, NAD pre-amp, NAD amp. I am glad I decided on this brand and would recommend this NAD tuner. It may look simple but it definitely feels well built for what it is, as do the rest of NAD's lineup.

Pros: simple to use, sounds great, has great reception, built solid.

Cons: just the ever disappearing paper manuals, but not a deal breaker for sure.

Solid Unit

Written by: Bob from California on August 9, 2015

Crutchfield Customer Review (What's this?)

I had an Adcom that died. The NAD is picking up a stronger signal. Seems like a very good tuner.


Cons: There are tuner/preamps out there. This is just a tuner. Just an FYI

I presume 5 being the highest rating. Good quality AM/FM receivers are hard to find. And your receiver I bought fits all of the criteria I set form. Being literally separate from the rest of your equipment means a great deal to me.



NAD C427 Tuner excellent value!

Written by: Robert W. from New Jersey on April 26, 2015

Crutchfield Customer Review (What's this?)

I have a 50+ year history with FM tuners, and have owned everything from Mcintosh tube tuners to internet tuners. I was looking for a reasonably priced solid state FM tuner to use with my high quality headphone amp setup (Graham Slee/ Grado GS1000i). This tuner is an exceptional value - good sensitivity, excellent frequency response, quiet background with the Blend feature. I am very pleased!

Pros: Good sensitivity (with a decent antenna), excellent frequency response,quiet background (blend circuit reduces noise yet still retains decent stereo separation)

Cons: None at this price- only slightly lower performance compared to the megabuck tuners

Tuning In...

Written by: Geoff from Washington on April 3, 2015

Crutchfield Customer Review (What's this?)

I was looking for an AM/FM tuner to compliment the Marantz PM6005 amplifier and CD6005 CD player which I purchased from Crutchfield. Initially, I considered both the Yamaha T-S500 and the NAD C427. Both had 40 presets, more than I will ever need, and both were recommended by those who purchased them. Perhaps the factor, albeit a minor one, which swung me to the NAD C427 was the RDS function. Pretty neat! The tuner is working beautifully.

Pros: Great reception. Tuning and setting up of the presets were simple. RDS function.

Cons: None

Best Tuner in this Price Range

Written by: Bret from Chicago on January 3, 2015

Crutchfield Customer Review (What's this?)

This is the best tuner I could find without going into the megabuck range. It gives you everything you want in a tuner and nothing you don't. The RDS display is a nice touch. It looks great in my audio rack. I describe the apparance as clean, elegant, and professional.

Pros: Great Sound Quality, Good Looks


My C 427

Written by: Mark H from Idaho Falls on May 17, 2014

Crutchfield Customer Review (What's this?)

I'm excited about this tuner. I like the looks, weight, and of course the way it sounds. I don't like that I have to order the full instructions to be able to use it properly. Other than that, I received it in 3 days from the good folks at Crutchfield. I've ordered and received other equipment from them and I recommend them.

Pros: Sound, and looks.

Cons: No instructions.

RDS: The RDS limits itself to the RDS PS (Program Service) and RT (Radio Text) function, both of which enhance ease of operation. The RDS PS will automatically indicate the name of the radio station you are listening to in the display. At the touch of a button, RDS RT will display additional information broadcast by the radio station, such as the presenter, the music playing, etc.

Fine Tuning: With each brief rotation of the C 427's front-panel rotary dial, the tuner will take 0.05 MHz steps for the FM band and 10 kHz for the AM band. You can also use the remote's numeric keypad to directly enter a station's identification number. Auto Search automatically stops at the next strong radio signal and optimizes tuning. Weaker radio stations can be tuned into manually. Stations that are quiet in Mono, but noisy in Stereo can benefit from the "Blend" feature that narrows stereo separation and improves noise. FM Mute eliminates inter-station tuning noise and only allows strong and clear stations to emerge from the silent background.

30 Presets: With 40 presets available, you can store all your favorite radio stations in any combination of AM and FM stations. To avoid having to scroll through 40 presets, the un-programmed (empty) ones are skipped to give you quick access to all your stations. All the preset information is stored in the C 427's non-volatile memory, which means it will remember all of its preset information even if the unit has been unplugged for a prolonged period.

Connections: The NAD C 427 tuner features a threaded F-type connector to connect the included FM wire antenna, and two spring-clip terminals to connect the included AM loop antenna (you can upgrade antennas). The NAD C 427 is fitted with a set of stereo RCA outputs and comes with a 38" audio cable to connect the tuner to your AV receiver. The rear panel IR input (3.5mm), +12V Trigger input (3.5mm), and RS-232 port allow the C 427 to be easily integrated with sophisticated system controllers used in custom installation. The tuner also comes with a detachable 6.5' AC power cord.

Simple Operation: Instead of littering the front panel with seldom-used buttons and features, the C 427 concentrates on the essentials. It features an intuitive user interface with a 24-position rotary encoder knob to quickly tune stations or select preset stations. The included IR remote provides wireless operation of the tuner.

VFD: The C 427 features a Vacuum Fluorescent Display which provides visual information on the settings, conditions, status, and other information relevant to the currently tuned station. The display offer three brightness settings.

Sleep Mode: The tuner's Sleep Mode timer will switch the C 427 to "standby mode" automatically after a preset number of minutes (30, 60, 90, or Off).

4 questions already asked

Being that your soundbar has RCA inputs it will act as the amp in this scenario. [ Daniel  Apr 25, 2016 ]
DA, This is simply a tuner, nice quality, but does need an amp. Output is straight line level, intended to plug Into preamp/amp. There is an RS-232 serial cable connection to a PC, etc., but I have not used that interface, so cannot help out there. [ Ulf  Apr 23, 2016 ]
Assuming that the soundbar has its own built-in amplifier(s), I believe you would connect the tuner directly to its RCA inputs, assuming that they are not otherwise needed. [ Obie  Apr 23, 2016 ]
I replied yesterday to your question about HDradio, and assumed when I bought this unit that it did bring in HD. So I looked in the manual, and it does bring in RDS, Radio Data System, a small digital input, it is not HD. Sorry for being misleading! The sound is quite good, all I listen to is FM broadcasts, but live in a quite rural area, so stations are oftenquitedistant, but still very good reception. Would appreciate a reply if you find more specific information. Good luck [ Ulf  Jan 05, 2016 ]
no it doesn't support hd radio its a high quality old fashion tuner. I could also do without the v in most audio products. good luck! [ VINCENT  Jan 05, 2016 ]
The NAD C427 does not support HD (digital) radio. I, too, wondered why this seemingly easy-to-provide feature was not available in mainstream, or even somewhat high-end, tuners. [ Obie  Jan 04, 2016 ]
17 1/8" W x 11 1/4" D x x 4" H It is a great tuner! [ Ulf  Jun 17, 2015 ]
Width is 17 inches. [ Obie  Jun 17, 2015 ]
WIDE IS 17.1/8 - DEEP IS 11.1/4 - WIDE IS 17.1/8 AS PER MEASURE BY MYSELF. [ KHUONG  Jun 17, 2015 ]
Dan, you're in luck...the dimensions are 17W x 4 h x 11 1/4 deep. I love mine, hope this helps MCH. [ Mark  Jun 17, 2015 ]
its 17 1/8x3 15/16x12 7/16 hope that helps good luck! [ VINCENT  Jun 17, 2015 ]
The front panel is 17 1/8" wide. [ Greg  Jun 17, 2015 ]
The unit is well made, great sound. My older NAD had the LED light burn out on the display, so replaced it with this one. Very nice sound, good reception. I'd say it is worth the price. [ Ulf  Jun 17, 2015 ]
We have not received any answers from other customers on your question. I think this will likely come down to the kind of performance you are looking for. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help determine if this tuner is right for you, and discuss other options if it is not.
