I am looking for a USB DAC as an upgrade from my M-Audio Transit to use with EF1 amp and HD600. I was thinking of emu 0404, but after I saw how big it is I give it up. How about emu 0202 or Fubar II? I would appreciate if anyone could comment if these two are truely an upgrade from Transit or...

Any rube rolling recommendation for EF1? I read suggestions for RCA cleartop, tong son, and mullard. Could anyone detail how different tube would sound differently? Basically I want one for larger sound stage, great details and dynamic for classic, and another one for warm and enriched middle...

I am looking for a <300$ amp to drive my HD600. EF1 and 336se stand out as good options. I read in one thread that EF1 is better than 336i in all aspects, but 336se seems improved over 336i, and in another thread that 336seems match HD6x0 better than EF1. Wondering if any other comments from...

I just bought a HD590. Now i am thinking to get an external sound card to improve the sound quality, since my source is not good. I have a T20 and Latitude D600. Will an external sound card make a great improvement for 590's sound? Any recommendation? How about M-Audio Transit, is it able to...

First, thanks for all buying suggestions that i got in this forum. Finally i bought HD590, mainly because the sale on Amazon. I think it's worthy for a try as my first shot on good phones. I received my HD590. I really love it. I guess i will stay with it for a while, until i get more...

I am considering to upgrade my PX100 to either HD590 or HD595, because I want a better cans for listening classical and some reviews said both of cans are able to drive directly from portable CD or computer and sound not bad. I have no plan to get an amp now. Which would be better in terms of...
