Good amp for Tekton lore s speakers?

Agree with the room treatment suggestions. But how old are the Lores? Not looking at the website just now but my recollection is these are pretty high efficiency speakers. Bass lacking might just be a function of needing longer time to break them in. Someone once said, "bass is the last thing to show up". Let the Lores break in. Do what you can about the room (DIY panels you can hang and take down?) then start looking for a better amp. For $1500 (and if I'm right on the Lore efficiency) you should have a nice range of options...especially if you are willing to buy used. Tubes aren't out of the question.

I had the standard Lores and loaned them to a friend who had a pretty much untreated room. In my room they sounded much better than in his room, particularly the relative lack of bass (too much hi freq sounds a lot like not enough bass).
I don't think a tube amp will do anything. I think the EQ idea is a very good one. I was thinking something with tone controls, but an EQ will probably do a better job.

Amarra has a nice EQ,Try the 15 day free trail.I have Audirvana and am pretty happy with it,,but I sure like the EQ on Amarra.

I have a pair of Lore S speakers and run them with a new Jolida JD502CRC. I felt this amp was a great value. I feel they match well together. It took a long time to break in but was worth the wait. I also thought the Decware amps would be a good choice but I liked having a remote. The Lore S is an amazing speaker. Enjoy

I am strongly inclined to agree with the above posters - you're sound is too bright secondary to far too much hard/reflective surface in your listening room. Your options? I think the most cost effective one would be to do something about the room - simply hanging draperies should help a lot. Further, if you can put thick throw rugs or a largish carpet/rug on the floor. Another trick wold be to have soft, fabric-covered furniture - great for lounging and controlling the brightness of hard surfaces as are bookshelves with books/albums on them.

My 2nd choice would be the equalizer...that is a hard one for me as I am a bit of a purist. If at all feasible, I either defeat my tone controls or leave them at the 'flat' setting. But, in your case, an EQ may be necessary.

Regarding amp, if I correctly recall, the Lore's are mid-90s in efficiency. With $1500 to spend and that level of efficiency, you have a large world to explore! Definitely peruse the A-gon amps for sale & auction. As pretty much all of us here are audiophile addicts, we tend to treat our gear as well as our offspring. That translates to being able to pick up well-cared-for gear at prices far less the full retail. Take your time and do the above things first. while undertaking those projects, keep a watchful eye for some candy on A-gon.
