The Musical Fidelity house sound is clarity and a big mid-range. The idea is to produce a sound as close to the original recording as possible where bass and treble do not dominate and are more to the background. As a result the bass is there and it is as clear as a bell, but if you like rock with a driving bass sound, it will be a bit dull, lacking in dynamic to your ear. The clarity and detail I get is immense and I have put back some of the dynamic with other kit in my system.
I have recommended a headphone amp before where the feedback was, it did not improve much over the original amps headphone out. So if you are an occasional user, not sure. But if you want to spend evenings with the headphones on and get the best sound, a dedicated amp is definitely worthwhile.
Thanks for your reply idc
I don't think in that case that the Musical Fidelitys are for me. I find the AKGs, although not properly run in (around 20h) and without a dedicated amp, lacking in the bass department, which makes the music I listen to sound a little bare. I found with my other phones I was using, there was too much bass which made listening for long periods fatiguing. I am glad I bought these (they produce a great amount of detail) but I just have to partner them with an amp that fills the sound out a little more.
