I finished building the Bugle Pro a few days ago mainly for playback of my 78 collection.
I found the quality of the PC Boards and the directions nop notch and easy to follow. I took around 3 evenings to put it together and it worked the first time I hooked it up. I own a Rega MM Phono amp and an Ear 834P and found the noise level of the Bugle as good or better.
I tried both twisted pair and Co-ax on the inputs and didn't find much noise improvment with the Co-ax over the twisted pair.
Thanks and I look forward to my next Hagerman Kit.
Take Care
