VDN OTL Amplifier Home

      Who are we ?
VDN OTL Tube Technology is a Trademark for audio products that
are being manufactured in Croatia, by our company - VDN Elektronika d.o.o. The company was estublished in 1992. by the two University degree electrical engineers - Mr.Ivo Vodanovic and
Mr.Zlatko Doresic. Company's primary business is the design of the special power supplies, specialized regulation circuitry and custom battery packs. VDN Elektronika is located in the city of Zagreb, Croatia's Capitol city.

     Why we decided to build OTL 12+ years, ago ?
The story is very interesting...11 years ago the first production
started, but the initial idea of building the OTL amplifier came
2+ years earlier, through a local audiophile, a close friend to both VDN's owners. And there was another one who not only belonged to the circle of audiophiles but was professionally involved with High End audio. With such a small team, but truly armed with all neccessary knowledges and experience, it was just the matter of time for successfull birth of the very sophisticated OTL amplifier. It took 2+ years to reach the prototype and almost an extra year to come to the production-ready REX-100 OTL.

      What we believe REX-100's highlights are ?
- beautiful, natural sound with extraordinary 3-dimensional stage and rich powerfull bass, which is more felt than heard
- very reliable operation, even with the toughest loads
- minimum signal path throughout the amplifier
- compact design which doesn't occupy much space in the room
- distinctive looks - simple, yet elegant
* after all, why "REX"; it is a latin word for the KING and we
believe it is...
