You want to know the reason Apple was so successful? The reason they, above all others, dominated the first fifteen years of this century and became a global juggernaut? It’s easy to talk about Steve Jobs and Jony Ive and smartphone innovations and iPods, but really, it comes down to one thing: keeping it simple, no matter how complicated a piece of technology was. If you could make it easy to operate, you’d have them. While we’re not directly comparing Peachtree Audio to Apple (we’re fans, but we’re not stupid), the Bellevue, Washington company shares that guiding principle with the Jobs juggernaut. And with the nova300, their landmark update to the outstanding nova150 and 220 amps, they show that it still works. What they’ve made is one of the most powerful amps on the market, which also happens to be one of the easiest to operate. It’s quite a trick.

Design:

One of the things that companies who build A/V receivers get wrong is that they make them way too complex. All most people want to do is connect up some speakers, maybe fine-tune the sound a little, and then settle down to watch Game Of Thrones. And yet receiver companies festoon their models with buttons and logos and weird features that maybe one in two thousand people will ever use. Fortunately, the Peachtree Audio nova300 is a stereo amp, not a home theater receiver, and its dedication to simplicity is absolutely joyous.

It's a big beast: a giant, rectangular construction with smooth housing, an all-metal front end, and two enormous vent sections on top. It’s big enough to be imposing if you want it to, but the design of the front end and its slim vertical profile is such that you can tuck it away out of sight - as long as you give it adequate ventilation, of course. While it’s not unexpected, or even necessarily a bad thing, the top of the amp does get reasonably hot during extended operation.

The reason why we rave about its simplicity is that, despite the fact that it packs huge amounts of technology inside it (which we’ll talk about in more detail shortly) it is amazingly easy-to-use. Connect your sound source to the extensive input and output section round the back, turn it on, select your input from the line of eight buttons round the front, and start listening. That’s it. Lights along the top of the buttons not only indicate the input source, but also the volume, and the volume pot itself turns smooth and sweet. 

It feels so easy. Even someone who’s never used a stereo amp before in their entire life will be able to figure it out. And really, when you’ve got an amplifier that allows you to take full advantage of all its technology with a couple of simple button presses, that’s something to celebrate.

A little about what’s going on under the hood. The nova300 is an integrated amplifier, meaning that it packs both pre- and power amps inside it. It doesn’t have the tube that was used in the 220SE and displayed prominently upfront, which is something we miss a little more than we thought we would (Interestingly, Peachtree told us that including the tube was the source of a lot of internal debate, and that they ultimately decided against it, opting instead to focus on clarity and detail in their circuitry. Fine, and it's obviously worked, but we still miss it. A little.)

The new amplifier circuitry is phenomenal, and if the integrated functionality wasn’t enough, you also get a headphone amp and a very, very good ES9018K2M SABRE32 Reference DAC (Digital-to-Analogue Converter). The DAC runs everything from 32bit/384kHz audio up to 5.6DSD, which is solid. We would have forgiven Peachtree for not including something like the DAC and focusing just on the amplifier circuits, but they made us really happy when they included it. This is a single-box system, one which can handle just about all your audio needs. According to Peachtree, this is the first digital amp that samples the power supply at 440k, which is substantially more than other amps.

You get a huge range of inputs and outputs, as well. You get two USB inputs – one for dealing specifically with Apple products like iPhones and iPads (you think it’s an accident that we mentioned the company earlier?). You can toggle the computer friendly USB input between 2.0 and 1.0 using a dedicated switch. There is a Coax input, two Optical inputs, an Aux input, a Phono input, and a ground connection for turntables. There are two speaker binding posts, a 6.3mm headphone output on the front end, and an input and output for the loop feature, which we’ll go into below, and a preamp output for an external subwoofer or power amp. Although our model didn’t have one, it’s also possible to install a WiFi module, allowing you to control your music wirelessly. This is an embarrassment of riches, and we’d have to think very hard to find an audio input that the nova300 doesn’t accept.

While we were more than happy to just use the amp as the centre of our hifi setup, it also has a couple of nifty features for integration. Firstly, holding the Aux1 button down will put the amp into Home Theater Bypass, letting it power the front speakers in a surround sound setup. While it takes a little work, in practice, to get this ticking over, Peachtree provide detailed and thorough instructions, and it worked well. There’s also a Volume Control Bypass mode, for when you want to use the volume control on your source, and a Loop feature, for adding in a separate audio processing device like an EQ. Not everybody will use these features, but it’s a mark of just how well thought out this amp is that it not only includes them, but makes accessing them and operating them dead simple.

As well-designed as the amp is, however, we do have a couple of criticisms. Firstly, the buttons on the front feel a little wobbly and loose, undermining the four figure pricetag somewhat. And secondly, the binding posts for the speakers, while certainly sturdy, are a little too chunky to use smoothly – and are at risk of spinning right off if you’re not careful. When so much care has been taken to get the user experience right, it’s disappointing that the build standards don’t quite live up to it. But these are minor things. The sheer amount of functionality that Peachtree pack into the nova300 – and the ease with which you can access it – means that it gets top marks from us on design.

The nova300 offers magnificent sound | The Master Switch

Sound:

One thing you need to know about the nova300: it is loud.

Now, we know that raw wattage is a poor analogue for measuring volume. But it gets you at least some of the way there, and in these terms, the nova300 is a goddamn monster. It’s continuous power is – you will be stunned to hear – 300 watts per channel, with a peak of 450. That is…powerful. Really, really powerful. Matching speakers to something like this was always going to be tricky – speaker and amplifier matching is a bit of a dark art, and while we weren’t worried about blowing our speakers, it was actually a little tricky to find a pair that would let us get the best out of the sound. Fortunately, our guys at SVS had offered to send us a pair of their Ultra Towers, which not only sound excellent and look like something you’d see in the Batcave, but which are quite capable of taking 300 watts of power.

Not that we restricted ourselves. Over the course of the month, we tested the nova300 in as many setups as we could. We hooked it up to our home theater. We tried it with budget speakers. We ran every conceivable sound source we could into and out of it. Had holding it upside down and giving it a good shake actually yielded something we could use in the review, we would have done it. Fortunately, we didn’t need to, because no matter what was going into the amplifier, or what we were using to listen to it, it never gave anything but a brilliant performance.

It’s not just that it could go loud when we asked it to. That was a given. It’s that the sound was absolutely extraordinary. It had such fullness to it, such weight and heft, that we almost expected the air to turn solid. Even at low volumes, it delivered a performance that imbued the music with life. Basslines growled and snarled, kick drums reverberated deep in the stomach, mids and vocals felt like they’d be warm to the touch. Snares were as crisp and sharp as champagne. 

It gobbled up absolutely everything we threw at it, spat it back out, and begged for more. Even with incredibly dense material, whether low frequencies could have so easily gotten muddy or muddled, it never faltered. And we should point out that this wasn’t the case because we had it hooked up to a really, really good pair of floorstanding speakers. With a pair of budget bookshelf units - the Audioengine HDP6s, for reference – it was quieter but no less splendid. It drew comparisons to another excellent amp, the Emotiva Audio XPA3, but the nova300 was truly in a league of its own.

Perhaps the headphone output would be where it tripped up? After all, it can’t do absolutely everything well, can it? Nope. While we wouldn’t use this as a first choice for a headphone amp, it certainly performed well, lending some of that weight and presence to our headphone sound.

We listen to a lot of gear at TMS. Plenty of it has good, even great, sound. Very few pieces of kit deliver sound as extraordinary as this one. You have to hear it. 

The production remote - this time, with labels | Peachtree Audio

Accessories/Packaging:

Outside of the power cord, a lengthy USB cable, and a comprehensive manual, the main accessory the nova300 comes with is the remote. 

Our remote was mostly unlabelled - which we thought was standard until Peachtree told us otherwise, having sent an unlabelled one to us by mistake. They took the photo above as proof. We can report that the remote, labels or not, works very well indeed, with squashy, responsive buttons and a good heft in the hand. We were able to control iTunes and Spotify on our MacBook Pro, no problem.

Careful - the top of the nova300 gets hot | The Master Switch

Verdict:

Editor's ChoiceThere’s no denying that the nova300 is expensive. At $2,499, it’s a toy for serious hifi enthusiasts. Even among those, very few will have a demand for 300 watts of continuous / 450 watts peak power, which is way, way more than most systems will ever need (Peachtree, if you can believe it, are threatening to make a 500 watt version, which is mindblowing).

So there’s an argument that, as good as it is, it’s only worth it for a handful of people. We say: the hell with that. Yes, it’s expensive, but so is the latest iPad or MacBook Pro. And unlike Apple products, the nova300 hasn’t tacked on an extra grand because of the brand-name. It might be expensive, but it offers phenomenal value for money. It’s a complete integrated amp, and despite a couple of design hitches, the functionality and feature set it offers is just staggering. Even if it didn’t sound as good as it did, that would still make it worthwhile in our books.

As far as we’re concerned, this is the best stereo amp currently available right now (you can see how it stacks up against the competition here). If you have the money to spend, you should buy it. End of discussion.

Good:

  • Jaw-dropping, weighty sound.
  • Easy-to-use.
  • Great design and looks.
  • Huge feature set.

Bad:

  • Some build issues.

Alternatives:

Naim Supernait 2

Naim Supernait 2While it doesn’t have a DAC like the nova300, this is a comparable model in terms of sound and function, and a very, very good alternative if you can’t find the Peachtree.

We prefer the nova300’s looks, but that isn’t to say the Supernait 2 looks dodgy. Its imposing front-end gives good access to its feature set, and the sound, while not quite as deep as the nova300’s, is still superb. It’s got a huge range of inputs, and you can upgrade things with a range of power supplies. All in all, an excellent second choice.
 

Rega Elicit-R

Rega Elicit-RIf you can ignore the hideous remote and the need to pay attention when matching your speakers, this is a good one, too. Rega make some excellent amps, and at just over $2,000, this is a worthy opponent for the nova300.

Its sound is perhaps a little more subtle, with maybe a touch more detail than the amplifier under review here. We also really like the presentation. Rega is a British company, which means that this amp may be a little bit difficult to track down, but we still think it’s worth your time.
 

Cambridge Audio CXA60

Cambridge Audio CXA60 Not everybody can spend two and a half grand on an amplifier, but if you’re still looking for an integrated solution, then the CXA60 might be what you need. It obviously doesn’t have the sheer audio power of the nova300, but in the sub-$1000 range, there are very few amplifiers that can compete with it.

It’s got some excellent and well-designed Class AB amp circuitry and an included DAC, and we really like the design of the housing, too. While it might not be the most powerful amp available, it gets the job done.
