Considering the New Tekton Design Encores? AND Owners Group - Experiences/Questions

jcarcopo,
"Thank you" doesn't do justice to your detailed (and much appreciated) response!. You have answered my questions very well indeed. My only concern left is... what about bass? As I understand it, that is a weakness of SETs. That'll be my own little first-world problem to solve. Never heard an SET - ever.
As of now, $24k and up is out of my league.

mapman,
Pre is W4S. All is working well now that I have the 5000s located properly with the help of Ohm tech.

Thanks for your response. Yeah, room is limiting with left wall solid, right with 4-ft archway. Rear is mostly open which helps. I had a bit of boomy bass so installed a DSpeaker Antimode which takes care of that pretty well. SQ is good for now, but I still want to go to Encores.

Ok good to hear.  Is the soundstage and imaging better now?   That will always be different than others but elements of the recording/performers should occupy specific locations in the soundstage with most decent quality recordings.  
Do  good mono recordings  have a solid focus in middle of rear wall?   That is usually a good indicator things are set up well for proper imaging and soundstage with Ohms. 

That device sounds like it provides a lot of flexibility matching speakers to room. 
Having had an audition of double impacts safe to say Tekton will be a different beast. 
Cheers!

@coot Well, bass is subjective. I'm not a bass head to begin with. My Allnics provide ~10db of feedback and possesses ~10db damping to produce very tight, accurate, and even prodigious deep bass on thunderous deep house or on kodo drums for instance.  It's quite gut punching good. Most SETS are zero feedback designs, so they may approximate the deepest bass without the absolute control and slam that solid-state has to offer.  If your budget allowed I'd highly recommend the Line Magnetic 508ia 48WPC 805 SET amp for about $4600.  It's a premium quality piece with gobs of SET magic and way more power than you'll get from most low powered 300b SET amps.  Again, the Encores are 96db sensitive and 48wpc will get you plenty of amplitude whether it be bass or otherwise.  I really enjoyed that piece and at its price point its a relative bargain for such powerful SET amp.  Taylor at Goldprint Audio can help you. He's near me in NC, but maybe theirs a dealer closer to you.  If I can get by with 15wpc, you could be in hog heaven with 48 glorious watts per channel.  Regardless which way you go, I'm sure you're going to love the Encores, regardless.

I read lots of good remarks about the LM508 but I'd really like to stay with made in America or at least not made in Communist China.
