Sideways move. Different technology with very different presentation. Obviously will sound quite different, but not a slam dunk improvement.If you’re talking about the Proacs vs. Maggie 3.7s plus subs, no argument. I was just trying to put Audiolover718’s comparison into perspective--comparing some new $11K Proacs to 20-yr-old budget Maggies is hardly fair. Compare current Maggies plus subs (e.g., a *pair* of JL E-Sub e112s) in the same price range and it’s at least an even contest. Actually, that would be a *very* dynamic setup and still be $400 cheaper than the Proacs.
The BAT will not provide enough power to open up the Maggies fully unless it’s a higher current design. You likely will be disappointed in the dynamics, but enjoy the soundstaging properties of the Maggies.
The BAT *is* rated at 200 wpc into 4 ohms, so it is absolutely a good match for the 1.7s. My amp has the same rating. I will admit that the 1.7s on their own might sound a bit thin on large scale music in a space as large as SJ’s, but a quick sub or two with the right blending controls (continuously variable crossover down to at least 50 Hz, and continuously variable phase control 0-180 deg. or more) will get those Maggies with the 100/200 wpc amp to fully occupy a fairly large listening space. I’d say a JL Audio Dominion d108, Gallo TR-3D, or GoldenEar Forcefield 3 or 4 would do the job nicely.
