Congratulations on the new Adams, Marco!! It is gorgeous. I never get tired of looking at new Adams euphoniums. You are going to love it!!!!
As for the adjustable gap receiver, here are my observations and findings after having my Adams now going on a year (in May). If you make just a half turn or maybe even a whole turn one way or the other, you won't notice a whole lot of difference. To really see what is happening, I screwed the receiver all the way in and played a bit with that setting. Doing things like wide interval slurs and playing notes with wide intervals and leaps between them. Basically trying to land on the notes I was aiming for. I think you can call this slotting. Trying to land on notes at various dynamics and articulations. Then once you have a feel for the horn and receiver in the all in position, try screwing it out a whole bunch of turns, maybe 20. Here is where I really saw a difference, with the two extreme settings. Things could get sloppy and very hard to land on notes accurately. I think having the adjustable gap helps you find "YOUR" particular setting that works for you along with the mouthpiece that you use. I suspect I might have a little different setting if I used another mouthpiece(s). I talked with Dave Werden, who also plays the Adams (is an Adams Artist), too, and he and I both have the receiver in the range of 2-3 turns out from all in. That seems to be the "sweet" spot for me, and I think for Dave, too.
Now another thing, there are two different receivers that I know of, one is the nickel-silver that comes standard (I think that is still the case) and the other is a stainless steel receiver. I have both, and am now using the stainless steel receiver pretty much exclusively after long experiments with both. In truth, there is not very much difference in sound. There might be a little more difference in which receiver makes the player feel more secure.
As for the Marcus Bonna case, I have an E3 and it is fairly snug putting it in, but not overly. The E3 I think is a wee bit wider than the E1, so I would think yours would fit ok. I don't have any extra pads like Dave had in his for where the 4th valve goes. I think yours would be the same.
The sterling silver lead pipe is new to me. I did not know that Adams had that as an option, but I suppose being a custom maker, anything might be an option. Did Miel explain the reasoning behind the sterling silver lead pipe?
When I saw the springs, I was surprised at how "small" in diameter they looked. I thought these couldn't possibly do the job, but they have been just fine for me. I have not thought about switching them out as they seem to work just fine. I play some fast stuff, and I have no problem with them. I use Yamaha synthetic, I did not opt for the Monster oil that came with the Adams.
Anxious to hear your thoughts and experiences after playing it for a while.
Congrats again and welcome to the Adams family!!
