Magnepans VS MartinLogan for detail and sound staging

I am not sure if those Maggie’s can deliver what you are looking for, I have not heard them outside a showroom. But assuming that they can, I think you are limited by the all in one Peachtree solution. Getting to the next level would require some budget, avoid making a lateral move. 
 

In the meantime, you did not mention what you are using for a streamer, and very importantly what you are using for digital cable. Both can make a big difference. 

Hears a vote for the Maggie 2.7i’s.  I upgraded from the 1.7i’s about 3 months ago and am very happy. I have a small (16 X 12) room that is audio only. Just my Human Touch Perfect Chair (bad back, disabled) my audio gear and me. I have added 2 SVS SB- 1000 Pro’s along with the 2.7i’s. I have never been a “louder is better” kind of listener. I have measured my average listening volume, according to my phone app anyway, is around 80 dB. I drive those with a Carver Crimson 275, PrimaLuna EVO 300 Preamp and my media comes thru a Cambridge Audio CXN100

Go enjoy your music!

I was wondering the opposite thing. I've owned a pair of Martin Logan Advantages for over 12 years now. I love them. Originally way back when I owned an entry level sets of Maggies before swithching to ML's. Decades later I was curious about the newer Maggies and bought a pair of 1.7i . They now have at least 100 hours run time. I kept the ML's. Still doing comparisions, but no matter how I tweak the Maggies (more power, added in my ML sub, upgraded speaker cables to Nordost Frey2), the ML's still win out. The 1.7i's sound great but do not have the depth of soundstage, full background, and clarity of the ML's. The ML's are indeed a worth the investment, IMHO. Will likely sell my Maggies eventually. Don't know where you live but if you are in CO, I highly recommend seeing Rick at Audio Alternative.

Good luck!

Maggies all the way, provided you have enough amp for them.  There is no higher definition I have heard from a pair of speakers.  You can hear people talking in the background of Beatle recordings.  When I bought some Maggie 3.5r's something like 20 years ago, I listened side by side to some martin logan.  Amps were McIntosh.  I even remember what I was listening to sample; Dire Straits, Love Over Gold.  You can only speak for you own ears though.  Whatever amp you have may pair better with the one your own ears pick. 

@ baconboy: At my local high end audio shop, I just recently got a chance to audition a pair of Magnepan LRS+ speakers, augmented by a pair of high quality REL subs, and the sound produced by that combo was nothing short of spectacular!!! The Maggie LRS+/REL sub combo could easily do justice to any genre of music, if set up properly. No need to move up to the larger true ribbon tweeter offerings from Magnepan, as the LRS+ are truly something special, and can give you everything you ever dreamed of, if you add a couple subs with them, and, also, set them up properly. Ditch the Peachtree Audio, as you can do a lot better in amplification, in regards to getting the best sound quality out of your Maggies than with the Peachtree. About 3 years ago, I drove a pair of Magnepan 1.7i speakers with a top of the line Peachtree Audio integrated amp, and I was thoroughly disappointed. My suggestions: (#1) Keep your amazing Maggie LRS+ speakers, as the quasi ribbon tweeters on this particular speaker are magical and are out of this world. (#2) Replace your old and antiquated sub with a "PAIR" of quality modern subwoofers (REL subs would be perfect) (#3) Get yourself a more high quality sounding class A/B amp (250 WPC+). If you make the changes that I’ve recommended, I truly believe that the sound quality that you'll achieve, in your size room, will absolutely knock your socks off, as it did mine at the audition!!! Happy listening.
