Can I Even Play Non-Compensating?

Yes.  A non-comp euphonium is like a single rotor bass trombone.  Plenty of music can be played and any note can be lipped in tune.  The euphonium also has several slides that one can pull to prepare for an exposed note that otherwise might be less in tune with only valves.  For a low Eb that must be right on, if 1-2-4 does not spark joy, pull the 4th slide and play it 1-4.  Your adjacent C and F notes can be played 1-3.  For low C near the pedal BBb pull 3rd or 4th slide some and it's 1-2-3-4.  Low B, no one writes those, but you can fake it 2-3 and be stronger for it.

Though many non-compensating euph players and tuba players may be more used to the 4-on-top and all-right-hand valves, this 3+1 setup lessens the struggle with awkward fingerings by moving the 4th valve duties to the left hand.  Once you get used to it, things are easier.  Example:  low Eb to low F with 4th slide pulled as above:  1-4 to 1-3.  This is easier with 3+1 than 4-on-top.

Adjustable Receiver

The mouthpiece receiver is adjustable so you can find the perfect insertion depth with any mouthpiece.  If you experiment for a few minutes, you'll find the sweet spot where the instrument resonates and responds better.  Why not have this exclusive Adams advantage?

Compared to What?

The Adams Sonic costs about $1000+ more than the King 2280SP or Yamaha YEP-321S. That's some cheddar, but you get flawless European craftsmanship, adjustable receiver, Bauerfeind 3+1 pistons, and a very light Bonna backpack case.  It's about $3000 less than the E1.
