Feedback sample from our customers:
1.Hello Mr Chen,  Yes I received my Little Dot 2 yesterday after a little go around with the shipper (DHL).All is well and it sounded wonderful for the few minutes I heard it last night. My wife loves the blue LED's under the tubes. I hope to listen more this weekend when I get caught up on my chores.Thank you again for a great deal on a wonderful amp! Please keep me on your list for future offerings.

2. Dear Zunqiu
Well, I received the amp today. I sincerely appreciate your concern with its shipping and arrival. It arrived in perfect working order, and I am using it at home already.I know that tube amps need to warm up and break in some, but I have to tell you that I am amazed with this amp already. I have both Grado and Sennheiser headphones, and your amp has already brought qualities out in them that I never knew existed. I also have a pretty decent professional headphone amplifier, and this thing blows it away in every respect. I am amazed at how easily the amp drives either set of headphones!I have often read about the superior dynamics of tube amplifiers, but I was totally surprised and shocked to hear it. I am also surprised at the low-level detailing that I can hear now. I put in the very first CD that I ever bought (20 years ago), Elton John The Concert in Australia (a must-listen, by the way), and I heard detailing in the orchestra accompanying him that I have never heard before. Jazz is absolutely wonderful, as well. A simple jazz trio recording that I have sounds better now through this amp than I even imagined it could. I thought that, being a tube amp, it would roll off at the frequency extremes, but this seems just the opposite. I expected a glorious midrange, but I did not expect such full bass (not over-cooked) and clean, natural treble. In other words, this amp has far-exceeded all of my expectations, and that is only after a few hours of play.You are building a truly wondrous product here, and I will, of course, give you a fantastic rating on ebay. I will also, and have already, recommend you to others. Please feel free to use this email as a whole-hearted endorsement. Thank you so much!

Could you say more about the 1B2 and 4P1S tubes used in this unit? As
there does not seem to be any American/European NOS 1B2 and 4P1S tubes
available, are there other tubes that could be used in their places?

I am sorry but maybe you misunderstood my question. Is there an
American/European equivalent to the 4P1S (Chinese) tubes? You say there
is a Russian one, the 4∏1∏, but I don't understand the letters
"∏1∏." Is this in the Russian alphabet?

We can use normal tube without the blue LEDs. But it just can
not glow as you thought due to the feature of the tube we used.
