Tekton Double Impacts

Thanks to @hobbyhands for this post, on another thread, of the Mini Ulfberth (? not named yet ?) which @jcarcopo is receiving.


"You might also want to see this speaker just went up. I drove down to Tekton and got to hear it. It’s a little larger than the DI, but definitely smaller than the Ulfberht."

Had to share:
Last night, I fell in love with my Di’s all over again. After installing a Bluesound Node 2, I was able to listen to MQA for the first time. Without going into all of the usual adjectives, let me just say that I found myself shaking my head over and over again, with a big grin on my face. I also heard myself say out loud, "My God." Listening to Sting & Shaggy’s 44/876, I could hear the incredible bass that the Di’s are capable of. Extraordinary!

My DIs will be delivered this coming Thursday (June 14) and I am struggling to decide on how best to power them.  It sure would be helpful if there was a way to catalog and post a standing list of components others have successfully used with DIs that includes room dimensions, treatments (if any), component MSRP, and a checkbox that indicates whether or not the reviewer compared different amps and if so which. 

I don't know what to expect come Thursday but I am committed to the 60-day trial to see if they offer something that other candidates I've brought in have yet to.  My only challenge is to try to make sense out of the many recommendations.  One YouTuber says that a MasterSounD Box/DI combination delivers "great Synergy!" while another writes that their SET amp does the trick, another declares that solid state monos are the way to go, and yet another says that integrated are best.  It's therefore difficult to assess the strengths and weaknesses of each combination short of buying and trying (which incredibly, after speaking to several manufacturers, this "buy and try" methodology is frowned upon. When did manufacturers become so boldly self-serving?) but if THAT (buy/try/keep or return) is the bottom-line reality then, okay. 







  

     

@snovosel Awesome that you are trying the DIs out. What are some of the ’other [speaker] candidates’ you have ’brought in?’

The DIs are really versatile with amplification which is why you find folks driving theirs with a wide assortment of both tubed and solid state amplification.

I would start with the amplification type / level / brand etc that you prefer and are familiar it.

You haven’t said what you have been using...sharing that will be helpful for DI owners to provide more specific feedback. Sharing your room size, preferences, etc. will also help.

I personally feel that the DIs do best with some power, though others are quite happy with SET amps and have driven them to satisfaction with just a few watts per channel. I’ve driven them with both tubes and solid state gear ranging from (into 4 Ohms) 40 watts up to 500 watts (my current amp). Despite leaning and now being fully vested in solid state, my first/initial recommendation is to pair tubed components with the DIs, should that be an option.

Take advantage of the full 60 day trial, and run them as much as you can the first few weeks.

Part of the problem matching amplifier to these speakers is lack of a provided impedance frequency curve from the manufacturer. As the owner has stated, it is not required but I find myself gravitating as a consumer towards manufacturers that are more forthcoming with specific component parts and measurements. For ex, Primaluna I think does a good job with this on their website. DI measurements are still lacking and At this point all we can do is hope that stereophile reviews or time tested reports make their way. Although this thread is full of anecdotal reports and at 1500 + posts, it begs for organization.

I ran a test cd, at relatively low volumes , and subjectively evaluated frequency response, using an otl tube amp that is sensitive to impedance challenges:

I found a good response from 40 hz to 10k.
Like a bell curve,  20, 30,  and 11k, and 12k were barely audible

For some reason there was a significant dip at 60 Hz

and 800 through 3150 hz were the loudest frequencies

The unaccounted for variables are overwhelming But the drop at 60 is a bit puzzling. Unless I have 60 hz hearing loss among other possibilities. I wonder if anyone else has experienced this?
