If you had to choose...

Thanks everyone for all of this fantastic advice.   This is all very helpful.

I hear you all on the efficiency.  Yes, I listen at around 65db, for many hours a day and night. So, sound quality at low volume levels, and avoiding fatigue are top considerations.

@oddiofyl thanks for the review on the Revivals.  FYI, fellow Audiogoner nonoise wrote up an awesome review of the Revival Audio Atalante 3 for anyone interested entitled "Shout out to Revival Audio Atalante 3 speakers" 183204-355

@hilde45 - Thank you for the reviews and for the heads up on Carrera's bright tweeter.   That sounds like a non-starter for me.  I am listening easily 12-15 hrs a day.  I will speak with Fritz and get his thoughts as per your suggestion.

@zlone, @soix  Yes, I have read similar comments about the Alyssa's, so maybe not ideal given my current environment.  And I have added Reference 3A MM de Capo BE to my list!

@mofojo - Yes, I have been eyeballing the Heresy IV.  I forgot to mention that, so thanks for reminding me! This company has haunted me ever since we'd cut school and sneak a listen to Bowie on a friend's dad's Klipshorns (AK-6?) in the mid 70's. Blew my teenage mind!

@knotscott - Agreed, I will initially keep my ATCs for comparison, then if all goes well, then maybe sell them.  Yes, it is such a personal choice. So I am very appreciative for everyone's perspective.

@mashif, @celtic66   -  I have thought about staying in the ATC family. When researching ATCs for my purchase a few years ago, I seem to recall that the 19s just had a larger woofer than the 11s, otherwise very much the same, but I could be confused. I can't fit floorstanders, so the 40s wouldn't work. The ATC 20's are over my budget, unless I could find a super used deal... I do think though that my 11s prefer a bit of a higher db level than 65db to really shine.

I have been very happy with my ATC, just wanted to see what else is out there, given my listening space and volume levels.

Maybe I should just figure out a way to keep my ATC in addition to getting new ones!

Thanks again everyone.  I really appreciate it!

Cheers.

Thanks jastralfu.  I saw the Rev 7 SEs and the Ls7s on his website and was wondering about them, in addition the the ones above.  I will discuss these with Fritz as well.

Hi everyone, thank you again for all of the suggestions.  So, I recall now one of my considerations in selecting my ATC.  That they were closed port.  I have no flexibility on the placement. One speaker rear is about 12" from a metal locker , and one side is about 4 "from side wall, and the other speaker rear is about the same from a metro shelf that contains equipment, etc.

Should I be concerned about a rear port, need to plug etc in the speaker options discussed above?  I do have a sub woofer...

Also, does anyone have any experience with the Zu Audio DWX and think that they may be a viable speaker  "contender" for my situation?  I noticed that Jerred and company (Black Ice Audio) have been using them at the audio fests lately to highlight the Black Ice equipment.  

Thanks grislybutter.  

@steve59:  Thanks.  I will have a look at the Meridians.

@celtic66: Thanks.  I hear you on proper stands, room treatments etc.  But I am far from that nirvana in this room at this point, unfortunately.

• So, the speakers are sitting on Elfa tall (41 inch) drawer racks, which rest on my carpeted floor.  These drawers house all of my cables, adapters, computer, photo and guitar stuff, etc. So, very functional for the space constraints that I have.  But no room for stands.
• The speakers sit atop the Elfa's on studio monitor isolation pads and are not currently angled.
• The woofers are currently at ear level, toed-in just wide of my ears.
• I sit at my desk with my speakers behind me.  My equipment rack is right next to me at my desk.
• My side walls have multiple large photo frames on each side, and on the wall in front of me, along with a small basement window. I assume reflection horror.  

Anyway, that is my setup currently, and slowly trying to tweak it within the room constraints that I have.   Everone's tips greatly help!

Cheers.

@celtic66

Thanks a lot.  Agreed, less than ideal.  But, hey, at least this room/cave is all mine.  The family avoids it like the plague!
