So wrong to put it up commercially.
Speakers made from hollow logs, 12-knob preamp, straw mat acoustical treatments, and stolen heat sinks? Must be the 1999 North Korea high end show!
its Fyne speakers from UK actually....Speakers made from hollow logs, 12-knob preamp, straw mat acoustical treatments, and stolen heat sinks? Must be the 1999 North Korea high end show!

It is ok to copy Pass Labs for DIY home amusement. Mr. Pass welcomes people build their own copy using their own brain. It is not ok for a commercial enterprise to copy Pass Labs and sell it as a commercial product.
In the USA, theft of intellectual property can be prosecuted to stop the theft. Since this theft in Thailand cannot be prosecuted by a USA company, the only thing to do is to make a joke and laugh at it.
Making fun of theft is not an attack.

@ henry ...... it isn't that serious
however, every (unauthorised) cloner deserves at least mockery
this guy evidently is intentionally driving on Papatrain, while mimicking some originality
imagine him making same amps, but in different cases - still cloning, but less interesting to potential customers

the only thing missing is adjectives pertaining to Class A/B and BJT’s (except those made by Papa et al of course), and MZM and the likes.
Example: Jeeez, that’s a pretty class A/B thing to say man. Reply: Yea, I agree, like a poorly constructed 9 gain stage BJT IMD-packed preamp, dude

That is a great description of a cloner."Vile"? Moi?? Strange indeed. Must need to re-calibrate my international mockery spectrum, right ZM?

Imitation is a search for quick profits and sadly lacks of imagination and creativity
Age of Kali Yuga

Yeah. He started a record company in Berkeley when vinyl was a thing, and still is the largest independent chain of record stores in the San Francisco Bay Area.
