I was the author of that post on diyaudio. I have used my Bugle very satisfactorily to rip LPs to digital.
Others have used separate cases for the power supply and for the Bugle. I have found that the one case I used, with sufficient stand-off distance between the power supply and the bugle and with attention to grounding, lead length, and dressing, is dead quiet with headphones and high gain. The ground connection between the turntable and the bugle is important. If I remove that wire, noise goes way up.
If you design your own case and are pleased with it, why not post pictures so others can learn.
