Let us know your early impressions.
It sounds like you are buying them, so I'd suggest giving the Alphas time to break you in by keeping them playing whenever you are around.
The transition to and from a wave guide often reveals a heavy bias towards what you are familiar with. IME, after giving both plenty of time to burn me in, it ends up a "robbing Peter to pay Paul" proposition.
IOW, I can usually find content that plays better on each of them, to my ear.
Ha. Haha. Hahaha. Well I received them today. I cautioned the seller to take care in packing them and that if they were not sure about it to let me know. They of course ignored the message, sent the speakers, and despite the advantage of not having to go very far (less than 200 miles) they packed them them poorly enough to damage the tweeters. The only thing between the front of the speaker and the outside of the box was two layers of cardboard. Idiots.
I plugged them in and the bass is, erm, boomy? Side by side with the Interlude 10 (a monitor) they have such a boominess in the upper bass that they don't even have the illusion of extension.
They are significantly brighter than the IL10s and the midrange is understandably more "present" bordering on shouty.
Soundstage depth and width suffer, but now doubt that is in part due to their current positioning.
In short, easy listening the Alpha 40 is not.
Maybe I'd just be better off (not necessarily wiser) to conclude that my IL10s are as close to perfect speaker for my ears. Their faults don't destroy my enjoyment of music.
Side note. The Amrit Logos dig deeper and sound vastly superior in the bass region to the Alpha 40s in the same position the Alphas are currently in. The Amrit Logos have slam and authority. In this regard they beat out the IL10, but the bass of the IL10 is still very satisfactory for their size. The Amrit Logos have a narrower soundspace with less depth than the IL10 which gives way to my preference to the IL10s.
