despite my often finding @secretguy 's commentary here cynical, spiteful and crass, in this case i agree with everything he is saying about the maggies
as you know, there is much much written here on a-gon about maggies big and small, old and new - i trust you have read through those posts carefully
my short advice is you must try them in your home, as much as share my thoughts here, i would be the first to admit that others’ words cannot convey what these speakers can do, especially when one’s prior reference are speakers such as harbeths fritz's other nice box speakers...
maggies are very very special speakers when given a room environment (and amplification) in which they can shine -- they have a level of beauty, fullness, coherence, wholeness and purity/clarity of sound that is a simply level (or two) above
i would say start with a nice used set of 1.7i, get them on magna riser stands (many used sets are sold with them) outlay is quite reasonable,resale not difficult, try with and without subs (which i think you already have) - done right current gen maggies do not lack bass... though they don't produce the kind of pistonic woofer midbass in your chest 'punch' that some rock/edm listeners want
... and like pretty much ALL speakers extant, a pair of rels underneath bring them to a significantly higher plane of performance
get the speakers don’t worry about trivia like mods etc etc (those are minor and easy).... you’ve got a good amp for them now, as impassioned as i know you are in this hobby, experiencing maggies is a bucket list thing for you... one which might open a door to a new level of musical pleasure
