What science cannot declare, art can suggest; what art suggests silently, poetry speaks aloud; but what poetry fails to explain in words, music can express.

Hazrat Inayat Khan

Like film, performances in audio don’t just occur, they must be captured; we take for granted the artistry and vision of those who guide the recording process. Conveying these musical truths to the listener is the true Spirit of the Turtle.

The Spirit's heritage

A Boy's Dream to Reality

Making music, self-built amplifiers and a passion for reproduced sound with HiFi loudspeakers (Wharfedale at the time), started the quest for becoming a record-producer/engineer around 1979. In 1986 the dream came true. (On the picture the just released album of Supertramp, Breakfast in America.)

If Kuijken & Co are playing Mozart piano quartets and Bert van der Wolf takes credit for the recording one might as well buy it blindfolded.

Adrian Quanjer | HRAudio.net

...there are some absolutely stunning 24/352.8 PCM recordings out there from Northstar Recordings that may just be the finest I have ever heard...

Richard Murison | Copper Magazine

A realistic sound stage and surround depth, with no disturbing noises from the audience or unwanted echoes from the walls. But with NorthStar Recording Services in charge, that does not surprise.

Adrian Quanjer | HRAudio.net

It’s generating so much emotional impact that every hair on my arms and neck starts to arise

Werner Ero | HiFi.nl

No wonder that it has become a wonderful album, partly thanks to the recordings made by Bert van der Wolf at two different locations. The fact that they 'coincide' perfectly with each other in this regard is partly due to Van der Wolf's craftsmanship.

Aart van der Wal | Opus Klassiek

Well, all I can say is that Bert's recordings are now firmly ensconced in my bucket: "if Bert recorded it, just get it, you'll most likely enjoy the heck out of it."
