Believe me, nothing can better than UM1/2(maybe W3) when you running, even the custom ones.

Starving Student looks good, but I don't think I can build one by myself. Sometimes we use same stuff but the sound are different.

It's a Desktops one I think, and maybe I have seem it somewhere before....

I think ER4p/s is the best choice under $200. I think it's a little like my K240DF but not K240M. Sorry, I have no idea about the S. But I think you may like that kind of sound.

I don't like superfi 5pro at all, I tried it only 15s, I even like superfi 3S more than 5pro. I think SE530 will be a better choice. or maybe you can try the new W3. Anyway, I havn't find an IEM has similar sound with HD595.

I think Lisa3 is more powerful, I can hear more difference with K240M than ATH A900LTD. Onemore thing, the Lisa3 has hiss but SR71A has not.

I don't think Lisa3 is a "Porable" amp. You can hear the difference between and LISA3 is really great and better than SR71A, but not day night difference. Anyway, SR71A is amazing.

I had those two at the same time.LISA3 has a little better SQ, a little more powerful, but SR71A win the others.

I think there is a Sextett on sale in headfi.

Now I only have a Tomahawk.....and it should go...Tomahawak can't drive both of M and DF well.

I think Zen vision:M's Line out has good sound with deep but not fat bass. I like it. I think you can find the DOCKs in Qables. But I have no idea with Fiio E5.

I only know there is a big development between Tomahawk and SR71A. And I don't think there are many people trying the P-51.

Thank you for your review. Can you talk more about the difference between STAXs and ATHs. I am interested in STAXs, but I don't know if it's good for me.

Why I can't wear K701 comfortable. I love the sound.

with My MD, I choose and only can choose MD SP..I think it's OK for outside. At home I will use my CDP

I think there are still some difference between K240M and DF. DF is a little harder to drive than M.

Ss have better SQ than Es, but I don't know the difference between S638 and S615. Thay look different.

Great! and now I will sale my Tomahawk.

ER4S/P is good choice if you don't care getting a second hand one.

Quote: Originally Posted by Uncle Erik I haven't heard the M model, but the DF is wonderful with tubes. $100 is a tight budget for an amp. I don't know what's available in Europe, but in the US, old two channel receivers are plentiful. Some are very good with headphones, too. Here...
