Recommend me a headphone AMP?

[AMDPower]

Hi

I was wondering what others would recommend as a headphone amplifier used mainly for gaming and movies and some music. This amplifier is to work well with DT990pro(600ohm), Hifiman400, Sennheiser hd650, ultrasone 900 and for a possible future upgrade of audeze lcd-x.

I was looking at something from the Schiit line but don't really fancy spending £500 not right now anyway and wanted something in the £150 range if possible, I can squeeze a little more if required but only if its worth it.

I was thinking of buying either MAGNI 3 , FULLA2 or VALI2 for the life of I cant tell the difference between then as I am not an audiophile except that one comes with a DAC built in and one is tube amplified. I am assuming buying the dac separate is better idea. I also know that you can use the built in DAC on the sound card, he has a separate ASUS sound card so if its possible to use that temporary solution that might be preferred so I can use most of the money to buy a better AMP and DAC later time.

I am also open to suggestion

Thanks all

Just wanted to say thank you all for taking the time to write a reply and for the help. There is a lot of information that i have been trying to digest in your detailed replies so apologies for the late reply.

I know my budget is rather miniscule in terms of requiring anything audiophile but this purchase would rather be a introduction and reading online about these matters can be rather confusing as many have conflicting views on a similar product. I don't expect much from my budget and I have a feeling that I really need to buy and see if it meets my requirements and if not try something better.

I appreciate there my be better equipment out in a similar price bracket but I have to start somewhere.

I have decided to give the MAGNI 3 a try and see what happens, if its disappointing then i will try another product. There is so much out there it become hard to distinguish features that would skew my decision on competing products.
