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

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.

coot, here are your amps:

i have an older pair w/o some of the upgrades these have, and they're very nice.  with power to spare; they can probably drive almost anything except really inefficient speaker in a big room.. 

if you want to bi-amp, the way to do it is with an active crossover set at 40-100hz, (depending on room and speakers), and a pair of subwoofers driven by solid state or class-d amp.  unless a conventional speaker's normal bi-amp x-over point is 100hz or less, i'd stick w/identical amps if bi-amping...

imo, of course.  😉  and, if you have room, i'd recommend going to actively crossed subs even if your main speakers go deep.  that's because most speakers that can dig even into the 20 hz frequencies have their first x-over point anywhere between 300hz-1khz.  and if they don't have to see that last 40-100 hz, the mains themselves will sound better, as well as the low bass sounding better.  and the amps driving the mains will also thank you!  probably a lot, if they're set amps?  😉

@cooThe Audio Mirrors @Sedond/Doug recommends are another high powered SET option as well. They're made in the USA at a very fair price. I've not heard them yet personally to offer any input on them delivering SET-like goosebumps and magic especially utilizing that russian 6c33c pentode being ran in triode mode. They are very beautiful amps though and definitely are a well thought out design considering their necessary protection system to prevent malfunctions if the tube decides to malfunction. 
I considered a similiar pair using that tube made by a one-off manufacturer in NJ. The amps were made in Vietnam, unbeknownst to me, and were very poorly made, even after a tech went through them and getting them working he just looked at me and told me to return them because they were of a poor design and were highly distorted way short of their rated power.  It was at this time I noticed the Audio Mirrors.  I reached out to the builder's Audiogon ad, but didn't hear back and around that time I discovered the Allnic A6000 Monoblocks and I decided to pounce on them.

If you go that route please chime in and let us know how you like them!
