  I review a significant number of US made  products, the Decware Zen Triode amp, Rogue Sphinx, and Sutherland Little Loco, to name just three recent ones. But a lot, MOST, affordable audio isn’t made in the United States or Europe. that’s reality, it’s hard to think of too many under $750 speakers made in the US, other than the Magnepan LRS. Other than Schiit (and Zen Triode), I can’t name another US company that makes electronics for under $1000. Of course once you’re spending a lot more money the choices of U.S. and European made electronics and speakers grows. But when I cover higher end gear some viewers complain about the prices, hey, US and European labor and the cost of doing business is MUCH higher! In any case, this channel will continue to present product choices over a broad price range.

  I've BUILT a 300b amp..   I can attest that it's a GREAT sounding audio tube.

  Hi Steve,<br>Thank you for the excellent reviews which I never miss.<br>I too have the same Boyurange A50. I did a few mods to it as recommended by your compatriot Steffie of Skunkie Designs, like replacing the coupling capacitors with Audionote caps and introduced two resistors to the output stage. Both these mods improved the soundstage and headroom. It&apos;s a significant change from the original set up. I still use the stock Psvane 300B tubes but replaced the rectifier and the 6SN7 with Electroharmonix. I live in Sri Lanka. &nbsp;Please keep up your good work.

  I bought this amp, and I am ecstatic. &nbsp;I do want to warn tube rollers. &nbsp;I tried EH 6SN7 tubes in place of the supplied 6N8P tubes. &nbsp;They are NOT a &quot;replacement,&quot; nor do they sound &nbsp;right for this amp. &nbsp;I then ordered two 6N8P tubes which arrived today. &nbsp;Without any breaking in they sounded like the original 6N8P tubes which came with the amp. &nbsp;They also came beautifully packaged in a metal box. <br><br>I have been listening to this amp since the beginning of October. &nbsp;For my listening tastes (mainly jazz, blues, folk, early rock, classical) this is the one I listen to most. I do not consider myself an audiophile. &nbsp;My main focus is on the music, and I want my equipment to capture the emotional power of music. &nbsp;I&apos;m not interested in specs. &nbsp;How a system communicates vocals, tenor sax, and piano are my main concern. &nbsp;This amp does it for me. &nbsp;I have literally wept while listening to music through this amp. <br><br>So, Steve, thank you, thank you, thank you for your recommendation.

  I have this amp and an Oldchen 845/300b. Both are incredible value. Paired with Zu Audio’s DWX’s really the soundstage is large and distinguishable. My preferred 300b tube is a Genelax Gold Lion. Sounds are airy, can be bright at times but not to a point of displeasure. I have pretty much upgraded all the tubes. You don’t have to, but this amp on many YouTube recommendations got me back listing to only tubes as my main 2 channel rig. <br>This amp IS worth a listen. I understand the whole “China” thing. I simply don’t have , as many of here don’t, that kind of scratch to blow on a tube amplifier. Sorry if I offend anyone but, it’s your loss. Thank you. Paul

  Steve, thanks for this review. Based on this I bought one last week. &nbsp;It arrived late Friday. I set it up and spent most of the weekend just listening and enjoying. &nbsp;This is my first experience with a full tube integrated amp, pre-amp tubes, power tubes and tube rectifier. Even with a set of quite inexpensive Jamo S809 speakers this presents a full-wall soundstage. It works best if you keep your eyes closed. Now I&apos;m probably going to upgrade the speakers to the Focal Chora 826, then maybe some higher end Psvane tubes. But this video started the process.

  The world has never seen such a hype with tube amplifiers as with the boyuurange a50 mkiii 300b. &nbsp;This is really the bomb in the hi-fi world. &nbsp;China is tearing up competitors, they simply have no chance.

  I have one of these and I have undertaken some simple mods as per a YT site - Skunkie Designs. These are fairly simple and cost very little to get the 300Bs performing near where they should.<br>One only needs modest skills and I am very happy with the results
