Emotiva Audio BasX A-150: Our Overall Top Pick for the HD650.

If you currently own a set of Sennheiser headphones (particularly any HD model), you’ve already made a substantial investment. Some readers have commented that they’re disappointed they need to buy a separate amp to get the maximum out of their new headphones. 

While it’s not an absolute requirement to get an amp/dac for your HD headphones, most experts agree that a high quality amplifier can improve their sound quality considerably. HD Sennheiser headphones (and similar high impedance models from other brands) were originally designed for music professionals and powerful studio audio setups.

If you have high end audio gear in your house you may not need one, but many modern consumers listen to music on smartphones, laptops or similar devices – and these compact modern gadgets are built with low-quality DACs that won’t do justice to your HD headphones.  Because of that, most users beef up their setup to get the most out of headphones.  

There are lots of different amplifiers capable of doing wonders with Sennheiser headphones. Below, we take a close look at the best amps for Sennheiser HD 600, HD 650 and HD 800 models.  Given the specs on these headphones, we’ve skipped the low end budget amps that really won’t perform well enough for these models.

We have included everything on our list from the very affordable Ocean Mini Valve to the top of the line Sony PHA3 and several options in between. See our detailed reviews below along with specific factors to consider,  depending on your budget and the model you currently own.

Best AMP for Sennheiser HD 600

The Sennheiser HD600 is one of the best headphones you can get when looking at over-ear headphones their price range. If you own a pair of HD 600, you’re already getting top notch sound quality offered by these headphones – but don’t be fooled, you can get a lot more out of them than you’d think.

This amp by Fiio also works very well with the HD 600. This DAC amplifier increases via a linear filter the quality of any audio device that you connect to it. The HD 600 has a lot of room to improve the general impact of your Sennheiser’s sound quality.

As an added bonus, they do wonders with the HD 598 as well! This is an affordable pick for anyone looking to boost their HD headphones without going over budget.

The floor noise generated by this amplifier is certainly one of the best you’ll find on its price range. It’s a great amp & dac combo capable of connecting via USB and offering a variety of different connections to your various music equipment needs.

They will surely work better on a pair of HD 600’s than a pair of HD 650’s. The 650 have a 300 ohm and this amplifier won’t properly channel anything above 150. It has been tried though, and they still create a very good sound even above the recommended ohm. It’s up to you if you’d like to buy this amp for a pair of 650’s, but we’ll be taking a look at better suited amps later on.

Best High-End AMP/DAC for Sennheiser HD 600

Sennheiser HDVD 800 Headphone Amplifier with DAC

Sennheiser HDVD 800 Headphone Amplifier with DACThis amplifier should be able to comfortably turn your laptop or music player into an audiophile-quality system without any issues. Being a Sennheiser product, you’d expect it to work pretty well with the brand’s headphones…and that is exactly the case. It works very well with the HD800 headphones, but given its features, you’re going to get the best out of its qualities with the HD600 and HD650 models.

There’s also one more thing that you should consider when you purchase this product: the best way to use it is with music directly downloaded to your computer. This means that the DAC software will not work very well with streaming services, and your music won’t have the same clean sound if you use an app such as Spotify with this device. 

Read reviews on Amazon from Sennheiser owners that have bought this amp.

This multipurpose amplifier comes with USB support, so you can set up everything pretty easily regardless of the device that you’re using. The product enhances bass like no other and improves the way in which instruments are reproduced through your speakers.

Best Tube Amp AMP/DAC for Sennheiser HD 650

DarkVoice 336SE Headphone Tube Amplifier

The design of the DarkVoice 336SE looks very peculiar, even for a tube amplifier. In any case, it positively influences the way music is played through the device, making it one of the best tube amps on the market.

It does take a little while before the device is able to properly reproduce music. This is due to the fact that the internal tubes have to heat up first after turning them on. It isn’t much of a problem, though: all you need to do is wait a bit and you’ll be ready to listen to your music.

The reason we’re recommending using this AMP/DAC with the Sennheiser HD650 model is because it gets the best out of the headphone’s upper mids. They’ll sound amazing in any type of music as long as you have your HD650 plugged in to this device. You’ll also feel like the soundstage is wider – not to the same extent as it happens with the HDVD 800, but it does bring it up a perfect amount.

The clean sound is one of the 336SE’s most prevalent features. You can try to listen through your headphones when there’s no music on, and you’ll quickly notice how NOTHING can be heard. The device doesn’t produce any inconvenient static or hissing noises, which brings up the music level exponentially.

Oh, and one more thing… Have you seen the product’s price yet? Granted, it isn’t cheap… But it is definitely way less costly than most high-end AMP/DAC combos. You’ll be paying less than half the price of other products for one which almost equals (if not surpasses) their quality.

If you use your HD650’s for gaming, having a quality AMP/DAC could make a real difference.

The features of this device are better taken advantage of if you own a set of expensive headphones.

This is one of the brand’s highest-quality products.

With a good set of headphones, your music will sound a lot better. If you don’t own a good set, this device will only make it sound louder. The HD650’s is ideally compatible with this product. The software is also well-made and supports any firmware upgrades that could be made – you shouldn’t need to worry about buying a new amplifier for quite some time.

Audiophiles might want to take a better look at DarkVoice’s 336SE model, but if you’re one of those who likes music on the go, this small USB device is exactly what you’re looking for. It’s highly likely that everything will sound better than any music you’ve ever listened to as a casual music aficionado.

What is the exact job of a DAC?

Best AMP for Sennheiser HD 650

The HD 650 is a top quality pair of Sennheiser headphones. They will deliver great sound quality with an open back design, just like its 600 counterpart. This allows both designs to create a great acoustic environment without generating the “roomy” eco that tends to happen with closed back designs.

However, the sound quality could be easily improved with an amplifier. Since the HD 650 already sounds pretty great, you might want to get your hands on one of the higher-end amps that you can find on the market. However, since we don’t want you spending your money blindly, we’ll tell you about our top amp choice for this headphone model.

Audio BasX A-150 by Emotiva

This high-end amp, although pricey, offers one of the best sound-improving attributes on the market. If you own a pair of HD 650’s, this amplifier should make them sound incredibly good. In fact, even if you own other professional headphones, you might want to get your hands on the BasX.

It powers up almost any type of sound device. The amp doesn’t break down easily and can sustain heavy wear-and-tear thanks to its top quality build, and its sound-enhancing features make it one of the best choices to power up an already powerful set of headphones like the 650. If you can afford them, we strongly suggest you to take a look at the BasX (check price and reviews on Amazon)

You can try other cheaper options, of course. The amps we recommended for the HD 600 should do a good job with this model as well (particularly the Ocean Mini Valve), but we do suggest purchasing one of the higher-end choices if you plan on getting the best out of your headphones.

Best AMP for Sennheiser HD 800

The HD 800 is probably one of the most expensive Sennheiser products on the market, but its high price is only matched by its amazing features.

These headphones, made for the audiophile out there, can sound even better than they already do – and we’ll tell you how.

This amp also works very well with most high-quality speakers and other Sennheiser HD model series headphones, but the 800 model seems to get a lot of benefits from the DAC1. Read Amazon reviews by HD 800 owners that have bought this amp.

Best AMP/DAC Combo for Sennheiser HD800

Sony PHA3 PHA-3 Headphone Amp, Black

Sony PHA3 PHA-3 Headphone Amp, BlackThis USB-compatible, incredibly powerful amplifier is one of Sony’s best AMP/DAC all-in-one products on the market.

If you’re looking for a headphone amplifier, then you most likely feel that there’s so much more that your HD 800’s can offer. And, if you don’t already own an amplifier, you’re probably right. The HD 800 is a very high-quality headphone model, but a proper amplifier with built-in DAC could definitely enhance its features to the fullest.

Such is the case with the Sony PHA3. The first thing you probably noticed when checking this product out was its size. Carrying this product around is absolutely easy; it has a portable and space-friendly design which most audiophiles are likely to appreciate.  

If you want to get the best out of the PHA3 with your HD-800 headphones, you will be better off by setting the HD800’s to its high-power balanced setting. Sound quality will improve massively, have no doubts about it.

This amplifier comes with a built-in battery which has a relatively sufficient life, but it would be better if you used it while the device is plugged in to a power source. It accepts audio input from any popular device regardless of its brand (be it Apple or Microsoft).

This product can reproduce digital data and sound like almost no other on the market. You’ll be able to clearly hear everything without having to worry about hissing noises or audio interference. It has balanced output features which you can use while operating on different channels, but the product’s single channel feature is able to provide you with more-than-good-enough sound quality.

Questyle DAC with Headphone Amplifier CMA600i-S

If your music player is filled with live songs and good quality music, this amp might be exactly what you’re looking for. It is a very expensive product, but you’re definitely paying for quality.

The balance of this device is able to bring your music up to the next level. You’re likely going to notice certain instruments and beats that you hadn’t even heard before – even in songs that you’ve listened over and over again.

The only clear limitation of this product is the quality of your recordings. If your MP3’s and MP4’s aren’t original or well recorded, you won’t be able to fully get the best out of this device. The build of this product is also very solid. It’s made out of metal and polished smoothly.

If you set the volume to a high level you’ll be able to notice how well it sounds. The product doesn’t suffer from a loss of quality at high volume levels – in fact, it thrives under it. If you enjoy using your HD800’s to listen to music loudly, this is the perfect AMP/DAC for you.

Still wondering if you really need an AMP for your headphones?
