Thanks, very much appreciated!
I wonder why so many variations of all those parts exist. Whenever I ask if using one instead of the other matters, one of the more experienced users will tell me NO. 😀

Variations exist for engineering reasons other than will make any differences at audio frequencies.
I think I may have to recase my Bugle2 as, in the standard plastic case, it picks up a lot of interference from Wi-Fi.
Some aluminium ducting is a quick fix and more attractive than wrapping in aluminium foil. Maybe lining the plastic case with foil would help ?

haha - good one! 😀
I suggest a metal case which has an earth terminal (connected to the metal of the case - not the anodised or powder-coated finish) is a better idea. Then a wire can be taken off that earth terminal to the earth on a wall socket or a mains-powered component (whose case is earthed).

Should work fine!
I use Modushop cases on all my gear - although not that one.
You know you can get them to drill the holes ... and engrave words?

uhmm ... i've heard about it but been too lazy to find out how to do it. does it require autocad or similar to create the files for it?
after spending the weekend reading "small signal audio design" by d. self i actually have to agree with you. in theory at least as i don't really know how this would affect my listening experience. but the bugle will be built very soon and the design suggested by d. self in the book will be next. so a real life comparison will happen - give me a few month. 😀
I was itching to try to make something and I saw this thread so I ordered up all the stuff. It was super easy to get everything and I spent a few hours over weekend making it.
My skill level is amateurish at best so it was a good one to try out before I did something more serious. When I first hooked it up it had something wrong in the right channel. After closely inspecting each of my not so very professional solder jobs I found one where the lead (is that what it is called?) wasn't trimmed down enough and it was bent and touching another solder point. I was able to trim that off and hook it back up and boom! It works great.
I have only used it for a few hours and I don't have enough experience listening to vinyl in general to say how it sounds or how it compares. I don't have any ground issues at all. My previous Rega Fono A2D had a ground loop issue that requires some monkeying around but this one works fine for some reason.
Overall I'm real happy and maybe I'll sell off my current phono and buy a new cartridge or something.....

Please explain.
I do not see "overload" in the published specifications.
The schematic alternates gains of 11 with 10:1 loss networks. If cascaded properly there "should" be no overload until the output.
What am I missing?
I think kamis refers to Doug Self's observations in "Small Signal Audio". I think Self says that passive RIAA usually allows for less overload margins than active RIAA.
I'd also be interested in a more detailed explanation of kamis' view.

"Usually" is a weak assertion.
_I_ compute (for 40dB gain) the Bugle2 will take 400mV at 20KHz, FAR more than any record or cartridge could throw at it.
The book goes into more detail of course .... the unscientific summary is from me. 😀
Can you share your knowledge on how to compute the overload margin for various frequencies?
Also i tried to look for useful information on how much overload margin is needed. I really didn't have a lot of success. What's your opinion on this?
