Horn speakers are really bright?

I went from a Squeezebox Touch to a Pi (Allo Digi One), then to a Node 2i and now a Lumin U1 Mini. All of them sounded different. In order:

SB, Node, Allo, Lumin

All are used with separate DACs. All the streamers sounded different on their own.

I do have ALLO USBRIDGE STREAMER with power supply I don’t hear any difference either 

to me the difference is able to pick in blind test yes there’s micro differences but doesn’t stand out
