Crown Studio Refrence 1 - $2,200 (amelia)
QR Code Link to This Post
It is an outstanding amp when run in stereo and in mono. The dampening factor is <20,0000. Over 2000 watts in mono 2 ohms and handle 1 ohm with ribbons (Apogee Full Range) and electrostats. These are great sounding amplifiers.
I am the 2nd owner, the box, packing, amp & manual are in great shape, no shipping labels on box. I have the FX card for xlr input.. Will include the 30 amp adapter plug for standard 15 amp outlet,
It was into a factory service shop for a turn on transisitor. that needed updated. and again for a hum that ended up being my cable, not the amp.
I prefer to sell as pick up.
I have a 2nd in equally good condition that can be offered for sale if interested in a pair.
