Super integrated vs equivalent +$$ for new main system


Just upgraded my main speaker and would like to upgrade the overall setup, room is a 20’’x30’’, listening to variety of music from jazz, vocals, classic, and a bit of pop. Speaker are M30.2XD and a Rel T7i, Streaming only, Qobuz mainly, and might add a tt later on. I have a lfd and qutest laptop in an other room with the P3s, main was a Uniti atom. Tried the lfd IV with the m30, sweet mids but lack on the lower and composure, dont want to go with a ncse as there is no remote and want something simple. From those of you who did these upgrade. Is it better to go for a super integrated, (thinking of 1: Audio Gold Is 1000 deluxe(150w- 2: Naim nova 80w) or going separate + fuss with cable, keeping qutest, going with a Auralic Aries G1 to stream, and choose an integrated amp class AB, ( choice I looked at and listen to 1: Supernait 3 $, 2: Luxman 507ux ii $$) luxman would stretch my budget but would be a keeper, I prefer a limited number of box if that is possible

Naim Supernait 3 is inadequate for the M30.2. It may sound good but not great. My experience with Harbeth speakers is they need current / power to sound great. Those who opined that Harbeth sounds great with flea-powered amps may be predominantly listening to mellow stuff or vocals. Play some dynamic music with bass and it will all fall apart.
You need a real good high current amp with the harbeths i would say that a good set of solid state separates would be the best for them considering that my large british monitors love the sound of big solid state they just do not come alive on current starved amps.
OP, please post your listening impressions after you've had a chance to demo the amps on your shortlist.  Those same amps are on shortlist of many looking for a good integrated, so all comparative data is helpful.
