Warning: China-Hifi-Audio.com

   If I have a choice, I buy from a country that is somewhat of an ally.These days I look at each piece of clothing or whatever and buy from somewhere other than China if I can. 
    No country has a perfect human rights record. But what the Chinese government is doing to the people within its borders is a justifiable cause for great concern.And we may only know a small amount, as was the case with the so-called "Great Leap Forward" in China in the late 50s and early 60s. 
     
      
     

Hmm last year right before the lockdown, I ordered a pair of Psvane ACME 300b tubes from them. And yes, it was a gamble to save some money by buying from them vs Grant Fidelity, but lucky for me, I got my tubes in a reasonable amount of time and the tubes have been rock solid. In fact, in my Cayin HA-300 tube amp (bought from New York-based Musicteck), 10/10 times I prefer the headphone output from it vs my Chord HUGO TT2's own headphone amp because of the more beautiful tonality, much larger soundstage, air, and transient.

So yeah, going back to the point, I was happy with them for my purchase.

I've done business with them 3 times.  Never had a problem.  Pretty quick with shipping too and I always got answers to my emails.  Late last year I had a quad of tubes ordered and they were taking a bit longer than usual.  I emailed them and it was explained they were a bit backed up with shipping.  They apologized and then refunded me 10% off the order.  I received the tubes about 8 days later. 

Another big +1 for apos.audio. A warning that ordering from them can be habit-forming...

That's why I use American Express. They LOVE to go after bad guys and will protect you no questions asked. That's why I have been a loyal customer for 30 yrs. They have ALWAYS helped me out.
