I am going to buy a Matrix M-Stage in the future and the opamp rolling sounds interesting to me. So far I have seen that the OPA627AP Class A biassed is a popular opamp for the M-Stage. Tamaudio sells these mounted and biased but I have heard that they use fake opamps, can anyone of you tell me...

I'd like someone's opinion on this topic please :)

I really enjoyed El Camino by The Black Keys

At the moment I am using an E7/E9 combo with a Superlux HD668B. I am planning to buy a Sennheiser HD650 soon and in the future I would also like to upgrade the E7/E9 to a better Amp and DAC. I have looked at the Schiit Valhalla+Bifrost and the Burson HA-160DS (which is about the upper limit I...

Having just received the Superlux HD668B I can wholeheartedly recommend them, especially in combination with the AKG240 earpads which improve comfort a lot. 

Faithless, I just really love their music and have all their albums at home

I am once again looking for headphones. I think I will go with the FiiO E7+E9 combo, or something different is there is something much better around this pricepoint (dac/amp), I have also heard of the Hifiman EF2A but don't know how good it is in comparison. So far my list consists of the...

Thing is, most services such as iTunes and Spotify don't offer higher than 320kbps MP3 files.

Yeah im definitely going to try them out in real life. To me the hd650 look a bit more comfy and they are 50€ cheaper. I think i'm going for the dac->amp->headphone combo, as the DAC in my iMac is not one of the best I presume. 

Thanks for the answers you gave me. I have yet to compare the DT990 and the HD650 in real life. I have looked at the price of the MKIV SE and with shipping and the probability of added taxes will make the price too much for me so that one is off the list for now.   I mostly listen to MP3...

bump.  Any suggestions on amps/experiences with these amps?

I'm thinking about venturing into headphone hifi. I listen to my music for about 4-6 hours a day so why not spend some money on it to enjoy it even more.  At the moment i'm thinking about buying either a DT990/250 or an HD650. I am looking for an amplifier that will drive these headphones...

Thanks, that kind of post was exactly what I was looking for. Now I just need to decide if I want open or closed and then decide what pair of phones I want. Anymore suggestion?

I am currently looking for new headphones. I am currently using a creative fatal1ty mk2 headset. It's ok for listening to music, but not for thoroughly enjoying and feeling music. Before this I used a sennheiser HD205 which I just can't wear, as they start hurting really bad after about a...
