Scott,
You need 2 devices:
1. The Piccolo (this will provide the 10-fold gain needed by the Denon.
2. A phono pre-amp. I highly recommend the Cornet2. I built mine perfectly and did not have the experience you have. I understand the Bottlehead stuff has a lot of point-point. None with the Cornet2, a high quality, large pcb. Very nice!!
You could just build the Bugle w/60db gain and do away with #1 and 2, but the above path is far, far better. Good luck.
