Nice Review, did you try 2a3 MK4? it has same price as ba so it's super hard for me to decide. I guess I really need to find a chance to listen those amps myself. And some people told me that 445 is also very good. Why they release so many similar products.

Thanks!   Do you know anything about that record?   I'm not sure which one I should get...

And I still don't understand that whether so-called "original" is vinyl record or the CD 1990.

No one get them already?

look that incredible discount, I think you'd better do not trust that website.

I still doubt that my mp3 can let them running well, though they are designed as portable headphones

I love that blue circle!!!

If you want to connect Dac/amp with computer, sound card is not important.

they are quite expensive...but good news is Black Friday is coming!

that exhaust thingy is absolutely stunning design

How about sony XB1000 good noise isolating, extra bass and...keeping warm   And I think k550 is no your style, because k550 do a very good job in stringed music

Do you want Noise Cancelling? you know it may affect music...

O2 is quite ideal, I will get one

But the desktop equipment is too hard for me to play. I think I should get a potable one first..

Thanks! I knew the weight is a big problem, but actually, I will not bring my amp to everywhere and I prefer to enjoy music in my room usually.

Hi guys,   Recently, I heard this amp and I saw this amp has many great reviews, so I'm interested in it. Is anybody knew something about this amp's real ability and style?

Any amp has different style, so the problem is how can I listen various music via one amp...However I don't want to buy 3 or 4 amps for different music....
