Need suggestions on preamp

@g2the2nd - I plan on getting a Sublime 531. I plan on setting a -24db slope for 50hz. I want to pair it with dual Rel T Zeroes. I know also upgrading the crossover with better components should improve clarity.

@saboros - I’m kind of the same point. I think the Mark II has more power but the 545 was so good. Detailed and only when driven hard does it sound harsh and Maggie’s are meant to be driven hard. I guess stuff like Monitor Audio would have been more detailed but I would have had to spend 2 or 3x more to get the naturalness and soundstage these guys have.

@skiznfliz - I’ve heard Martin Logan Tweeters and those are exceptionally detailed but I find they get fatiguing after a while even with a McIntosh front end but maybe if I paired it with some like a Conrad Johnson it would be worth looking at again. I’ve heard the Philharmonics are a great value. What amp do you have paired with them? I feel like you need something more lush to counteract the tweeter. 

Depending on your location, you might be able to find a used Benchmark LA4 for about US $2,000. I'd consider that a strong contender for detail and exceptionally low distortion.

Check out my system … Everything is listed…
I had Maggi’s for 3 years…I tried and I’ve got an Ok set up and they just didn’t cut it.
If you’re experiencing the issues you mentioned, I really don’t think swapping out a preamp is going to give you what you want. The Maggi’s have a distinct signature and the few people I know that had them who got rid of them have told me the reasons I got rid of mine were pretty much their reasons as well.
I’ve got one buddy who likes his 1.7’s but of one of the others I know actually said to me they were the speakers that had the shortest time in his listen room… At the beginning I though they were great, then after some time realized their shortcomings. Hey, LOTS of Folks Love ‘em, just feel if you’re comparing them to the sound you get from headphones, they’re be short lived with you to.
A properly crossed over speaker will not be fatiguing and once I heard a properly crossed over speaker utilizing a Beryllium tweeter I was sold ! Buying an off the shelf speaker and hoping it’s going to work in your room is a long-shot, esp if you’ve never taken measurements of your room’s acoustic values so you know what and how to address in order to achieve synergy with your room & system. Your room is probably the most important factor in achieving good sound from your rig.
You have a lot to think about, AJ at Sound Field might be able give you some insight helping you make a better decision for your situation.

I just sold my LRS+ that I loved in my small office. I lost the office to my kid's new bedroom. I used the Benchmark HPA4 preamp with it. It is the quietest preamp you can find and lets you hear the rest of your gear. 

I used to own the Parasound A21+ and it was great with the HPA4.With my LRS+ I used a CODA #16 and a Sanders Magtech amp with the HPA4. The weakest link in all of this was the LRS+, which is a steal for the price.

I also suggest a sub-woofer with the LRS+ and a preamp that can support a sub. I used the KEF KC62 sub.

If you like the coherent soundstage of the Maggies, consider a used pair of ProAc 1SCs or Tablettes, or larger ones if your room will accommodate.  It's odd to me that people around here rarely mention them, but years ago I replaced my small Maggies with ProAc Response 2's and I've never looked back.  They have the same seamless presentation and "disappearing act" but better bass and MUCH easier to drive, which opens up a whole different range of amplifiers in the 20-40 watt range.  A truly "classic" speaker like the LS3/5 and the Maggies, but more satisfying.  Beautiful vocals and solo instruments, and capable of full-scale classical as well.
