FWIW, I purchased a pair of Tekton DI's after reading reviews here and elsewhere. People were genuinely impressed and surprised by their capability while others were doubtful. I took a chance on these knowing i could send them back and be done with it. I set them up and was very impressed right off. After 30+ hours and a number of different CD's I have found them to be very very good in a number of ways. I also have tinnitus and I do not find these speakers to aggravate that at all. There were certain cd's I have played with my Gallo 3.5 reference speakers that my ears would not tolerate but played with the DI's they are spectacular. They are round tones, warm, natural sound to the ear. The tone and timbre are marvelous. The soundstage and imaging are, to me, impeccable. Very real and life like. The bass is rich and textured even at my lowest listening volume, which is 1!!!. I still can't believe it! I stay up too late now listening, and nobody in my small wooden house can hear it. There is nothing about this speaker I don't like and everything to look forward to. I will change some cabling to tweak the sound a little here and there. My wife, who is not an audiophile, but loves music, was never really engaged with the Gallo speakers. She is thoroughly engaged now with these DI's. Actually, we sit and listen together and we talk about life. We have been affected by the music. What blew her socks off was a James Taylor Live CD. We are literally in the room with all of the people. It is truly astounding and to be honest I didn't expect them to be this good. I feel lucky to have read these threads about the Tekton products and I feel even luckier to own a pair of DI's. I have the upgraded version. I have auditioned other speakers in the past, i have heard some other systems. I still remember the best sound I ever came across on Martin Logans with Mac tube gear. My system sounds as good, if nit better than that. I have a hz meter app on my phone and heard 21.53 hz on a classical piece. Very detailed, clear, balanced. Never is the bass, or any other instrument, out of scale. I am keeping these! It will be this speaker that I build my system around. BAT VK 500 amp, VK 51se pre tube, VK5dse tube cd, speltz silver IC's, speltz reference speaker cable, zu power cords. Zu was better than speltz power cord and it was my wife that could hear the difference when I switched it out.
There it is!
