Will this work with Beyerdynamic DT 990 250 Ohms, or will I have to buy a separate headphone amp?

I find I often can't get a hot enough level on my Sony MDR7506's when direct monitoring the mic inputs, so I'm thinking yes. Playback through the headphones isn't quite as bad, but to hear the mic pres adequately without clipping them is hard if I'm in the same room as what I'm recording.

I believe it will; both 1/8"-outputs are amplified, and I think they're individual amplifiers because there is no volume-change when the 2nd headphone is inserted. You might have some trouble with volume, as headphones usually have higher voltage than Audio-IN or LINE-IN (which is 1Vrms full-scale)

that depends, what kind of output is from the rear reciever? if it's either Red/White composite cables or 3.5mm headphone input, it should work just fine, if you purchase a wire splitter for both right and left inputs (since this amp only has one 3.5mm port and one Red White Composite.

Seems all you need is a toslink adapter with rca(I assume you mean red/white UGMA) output which would go into your receiver. Your headphone base unit should if into Eva output jacks on the receiver which should enable you to use headphones. If not I'm not sure if there is a toslink adapter with 2 sets of Eva plug outputs, if not the you would need a splitter to create the 2 outputs from the adapter.

it should work fine especially due to the higher ohm rating (higher ohm rating on speakers = less demanding on the amps)1 ohm = for every 1 volt it wil also demand 1 amp8 ohm = for every 1 volt it will demand 0.125 ampsthese headphones are 62 ohms so that means they are more forgiving on the power delivery abilities of a USB deviceusb = 5v therefore it will only need about 0.0806 amps and usb can supply anywhere from 0.5-5 amps depending on your equipment. I hope this helps.

Can't answer that for you, Alex. My previous headphone amp was an inexpensive (unsophisticated) analog, the "Boostaroo".

I'm not familiar with that model of headphones, mine fits in my computer as well as my speakers. I use an adapter to use on my guitar amp and it works very good.

I'm not sure I fully understand your question. This is a mono preamp that is used to boost the signal from an instrument before going into an amplifier or a mixing board. It is not meant to be used with headphones and if you plugged headphones into the output you would only hear it on one side since the output is signal is not stereo. I'm not sure what you want to use this for but you might be looking for a headphone amp not a preamp booster or something else..

So the resistance (Ohms of the headphones) tells you how easy it is to drive the speakers (produce sound). A higher ohms indicates that it is harder to drive the speakers; that being said that higher ohms means that the sound quality is better because there is less garbling of the signal. 30 ohms is standard and is appropriate for basically anything (mp3 players included) the 80 ohm can work with mp3 players but should have a amplifier, the 250 basically is useless without a good amp... if you want to get an amplifier I recommend the Fiio E11 portable amp (approximately 70 USD). Even if you get the 30 ohms DT 770 I am sure you will like it; I recommend getting an amp and higher "ohmage" if you want your music to sound just a bit nicer

sure it will. get the cable you need and treat it like a normal headphone amp

I use this with the HD 650 (300 ohm), this amplify the sound for weaker media players that can't provide much output power to the headphones, or to complement media players that need an extra boost in power output. This also provides a bass and treble boost if desired.

Yes it will, I have worn mine out and will be purchasing a new one very soon. Very good amp for the price and one of the better ones that I have used. The only thing I will warn you about when purchasing headphone amps is to make sure that you are getting one that works well with your headphones. Not all are the same and your more high end headphones require better amps. Get your specs and search for one that is right for your needs as this is not a one size fits all issue. Good luck and you will enjoy this purchase as its very flexible with many types of headphones. Have a great day!!

As-long you have a Left and Right on your headphones, and then can plug the single plug in to your other device."Should" most likely work.

The only reason you would need an amp is if your original source is limited. Otherwise don't bother. But if you really feel the need here is one source discussion I found. http://www.head-fi.org/t/635772/need-help-should-i-get-a-headphone-amp-with-v-moda-m-100

I have a samsung tablet and a pair of beyerdynamic dt770s which run at 250ohms. The amp is needed to drive them and it more than does the job. Totally different with them at such a cheap price. Actual sound is comparable to systems costing 5 to 10 times as much.

I am not familiar with your headphones but I have found that amplifier makes a difference but might denned on sensitivity of your headphones. I use it with my iphone an my cowen mp3player

No it will not pair well. It will have a problem with driving them since the amp is OTL. The output impedance is too high for 30 ohm headphones.
