Inexpensive Tube Amps

Read the current thread, First Tube Amp. The OP is auditioning a Yaquin, a highly regarded Chinese built tube amp found on Amazon.
  These seem to be a cut above the mass produced Chinese amps and may be a keeper.

Also, sensitivity of the speaker is not an indication of how well a low power amp will perform. You need to look at the impedance at any given frequency.

If YOU are referring to me, I know this is a different OP. Just informing him that I would not trust a cheap Chinese amp in the long run.
You get what you pay for.

I agree with @atmasphere , although I bow to his expertise.

@stereo5 , I'm sorry to hear about the terrible experience you had. Not to undermine your story, but on this forum I've read about a PrimaLuna and at least two Jolida amps catching fire.
  So what's a buyer to do regarding Chinese-built amps? Do we consider these occurrences a low percentage of failure and continue to buy Chinese, or do we stop buying these components completely? I don't have the answer, maybe it's buyer beware.
