Inexpensive Tube Amps


Anyone have any experience with the following?  I want to try one just to see how the sound compares to my Yamaha and Denon solid states.  Since the Denon is living on borrowed time I will likely have to replace it this year anyway.  Looking at the Nubsound and noted a Germtune that is identical to the Nubsound but costs a bit more.  Reviews are largely good including those on other forums.

Primaluna and Hegel…(maybe somebody already mentioned this) they're made in China. 
@simao first of all, this hobby is not dying out. Not sure why you would even say that.

Second, Will62 was treated fairly. He was treated equally just like everyone else that posts here. When anyone asks a question like his, the forum members will speak in the context of audiophilia (is this a word? sounds creepy). It’s not reasonable to come in here and expect that people are going to have great things to say about a $50 amp from China. It’s just not going to happen. And then to chastise those members for acting like an audiophiliac? That’s like my wife who yells at our dog for barking, digging holes and chasing cats.

Sounds like the only way Will62 would be happy is if everyone said, yeah, great amp! But since he didn't hear that, he's upset. Surprise! nobnody here's going to say that.

Yeah, audiophilia is a word. But it's not as creepy as the title of that briefly-lived magazine marketed towards cyclists, Pedalphilia.

Anyhow, I see your point, though I don't completely agree with it. I just hate seeing someone relatively new to the hobby made to feel lacking.
I read all the posts . And i thought these folks were trying to give their best advice that they could give on your question .I do not think they were rude trying to be rude.I think you really had your mind made up from the very beginning and were hoping to hear more positive replies. Good luck
