Best AMP for Sennheiser HD 600

The Sennheiser HD600 is one of the best set of headphones you can get when looking at products that go over the 200$ Price tag. If you own a pair of HD 600, you might’ve already noticed the 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 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 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.

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.

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.
