Anybody own or hear the Wavestream linestage?

Good luck, that's even rarer than the phono stage.

Have you spoken with Elliot at Acoustic Image?

He's the only Wavestream dealer that I know of and he usually has the amps in stock - don't know about Scott's other products.

I own a line stage. It was purchased to replace an Air Tight preamp. I bought it from Brian at the Analog Room. It is built like a tank and is far superior to the Air Tight, making the Air Tight sound rolled off and non neutral. The upper frequency extension is remarkable. It is dead quiet with plenty of gain. Dynamics and bloom are everywhere as it brings out the best in my Air Tight 300B amp. Highly recommended.
