I just bought a Little Country III tube amp. $399.00 which may be too much for you. You can get a Firestone Cute II for about $129.00. Anything less than about $130 and you really are not going to do the headphones justice. You should save your pennies because the proper headphone amp will make your new headphones shine.

Try the Musical Fidelity V-CAN, which is $199 at No pretty box, just the best they can build for the price. This company has a good reputation for sound quality, but I've never listened to this particular product. Also, Music Hall makes the OBH-11 at the same price point. Good luck; hope you find something you enjoy!

I bought a Cute Beyond amp for my Sennheiser 800's for $179, all Class A design, and cable for iPod to use iPod's line output for better sound than iPod headphone jack. Unfortunately, the $77 cable does not yet work with the new video camera Nano when formatted for PC's. Other than that, a great amp.

Try one of the Little Dot Amplifiers - good value for money - if you search for "headphone amp" in Ebay, their products should come up.

Since the Sennheiser headphone works well with music players and their headphone jacks, you won't get much if any improvement in sound with a headphone amp unless you can connect the "line out" of the music player or computer to the "line in" of the headphone amp. With iPods, it requires a special cable from the dock connector on the iPod to RCA plugs, etc. Going all digital, with USB input to a headphone amp can be tricky, since many USB processors in headphone amps have quality problems.

If you need it for portable use, try the FiiO E5 Headphone Amplifier. But you'll also need Grado Mini Adaptor Cable - 1/4 Inch to 1/8 Inch Plug.

What is your intended use? If it's for home listening, try one of Headroom's excellent models, or one of the other suggestions in this thread. For portable use with a music player such as an iPod, I suggest trying the $20 FiiO E5. Just got one for my iPod Nano 5g and Sennheiser HD600's. The Nano just doesn't have enough grunt to drive the HD600's adequately with some tracks -- the E5 adds just enough power to make the problem go away. I can't tell any difference in sound quality using the iPod as a source. When compared with my Home Headroom, it isn't as good, naturally, but then that's not what the E5 is about.

Haha, I don't know who would recommend a FiiO for those power hungry monsters, but it won't do much of anything for them. If you save up a bit, Headroom's crossfeed amps over at are REALLY nice, I own the Micro one for my K702s and it's just dandy. I've also read good things about Little Dot, but really if you need the top recommendations for your budget, go post on They're nuts, I'll admit, but they know their stuff and most of them that will post have had your headphones before and paired them with multiple amps. Good luck to you and sorry about your wallet.

Yes. Like some of the other posts have said don't go with Fiio. They're great for lower priced headphones but the 650's are power hungry monsters! I know, I have a pair! My setup is Asus Xonar Essence ST - Schiit Asgard - HD 650. That combo does them some justice! Don't deprive the monsters!

Definitely look at the objective2 headphone amp, you can find loads of information about it and it's design by googling "nwavguy" who is the designer. It can be bought from Jdslabs for around 160, or a little cheaper in eBay. But read about it if nothing else.
