TW-ACUSTIC RAVEN AC ANNIVERSARY TURNTABLE

To celebrate TW Acustic’s tenth birthday in March 2013 we present the “Raven AC Anniversary”. The Anniversary represents a new statement in turntable manufacture. It is based on the Raven AC chassis, machined from our well-known proprietary custom compound with a screwed-in stainless-steel plate. The Anniversary’s platter is a composite construction consisting of 40mm thick copper fixed to a 20mm thick slice of our proprietary compound. Consequently, the platter is basically equal to that of the Black Night.

Our anniversary model has a very solid armboard machined from 30mm thick aluminium. We can provide the relevant adaptors for every tonearm. To achieve the correct mounting distance, the position of the adaptor for your particular tonearm can be adjusted steplessly in the slot in 1mm increments. To facilitate this we have etched a scale on the armboard showing 210–310mm. Should you wish to install more tonearms, extra swivel bases can be installed as before with the original Raven AC. From an acoustic point of view, the Anniversary offers the same advantages as the Raven AC, but thanks to the modifications keeps a firm eye on its bigger brother the Raven Black Night. Similar to the Black Night, the Anniversary lets the music flow, yet remains composed and pairs dynamics with incomparable transparency.

It is rare in this class to experience such resolution and dynamics in music. With the Raven AC Anniversary we bring you a big step closer to the ideal of real high fidelity musical reproduction.
