I had the opportunity to test it and it is in line with TB1 Studio Project, or T-Bone SCT700 or SCT2000.
Chinese manufacturing coming out of the same factory SE Electronics, T-Bone, etc. ... Studio Project
An excellent microphone, but you can come across as an excellent way: Reason for this: the Chinese lamp comes with

A BIG TIP: THROW THE CHINESE LAMP AND YOU BUY A LAMP VINTAGE MILITARY TYPE SYLVANIA TELEFUNKEN Mullard Brimar MAZDA ETC ... 60s in NOS (new old stock)

That day and night
There you will have a microphone ... phew worthy of a big studio

There is a microphone the same: RFT Telefunken M16 at $ 1500: Look no more: it is the same but with a Phillips lamp

Look carefully on the web, you will find good lamp for cheap + price of the apex 460 you'll get 6-7 times cheaper than the Telefunken RFT M16

And if you want to push the envelope, change the capacitors in plastic polypropylene WIMA capacitors for the 3 and scr petis for the 2 largest (with that out of breath at all if there ever was and that it is not due to the lamp)

And there was the cheap microphone Top (knowing that basically there is already good)

OVERALL OPINION

Excellent value for money

For small budget c is the ultimate in tube microphone with T-Bone and SCT2000 Studio Project TB1

Lamp interchangeable (unlike SCT700 on which it is welded)
So customizable with a better light (I recommend) with 12AX7 or 12AT7 vintage
or with modern 12AX7 electro harmonix eh like € 10-15 who are not rich but very good nonetheless.
