Tekton Double Impacts

Hi Tom  (Mac48025),
I'm happy for you,  it sure seems as though the Aric KT 88 SEP amplifier is going to be an excellent choice with your Double Impacts.  I'm very interested to see what you think of them.  If you don't mind I'll invite myself over to hear this pairing 😊😊.

Vitop - Ribbon tweeters sound great and when integrated with cones, seem to provide wonderful air with dynamics, so going with the Tekton DI's as opposed to hybrid ribbon/cone speakers like the Salk HT2-TL or Legacy Signature for a bit more $ has been a tough pill to swallow. The Seas drivers used by Salk with RAAL ribbons are great and the "get what you pay for" feeling is ever present. Perhaps the sum of expensive parts in one speaker doesn't always have the synergy a well designed speaker has with cheaper components.

Listening to DI's has not materialized, unless someone in the L.A. area chimes in. My "case closed" comment was coming from a position of having read the entire thread full of rave reviews and feeling like I may be overshopping this. Your right though, I shouldn't just take your word for it. These forums have been fun but they really can take time. Valuable during upgrade season.

@brotw   Thanks for the added perspective. It's very helpful. Always good to know and hear more about takeaways based on what we are communicating and reading in these posts. As all of us are different our interpretations will be different as well. In this case, I can see myself coming to the same conclusion as you did. As @vitop mentions, you'll have a really good feel for these aspects of the speaker for yourself, apparently in short order! : )

Like mac48025, I'm also using Herbie's Gliders. I went with the 1 inch length for the threaded Giant Gliders since I didn't need to adjust height or tilt and wanted stability...the Gliders are flush with the speaker base. If you want the flexibility for tilt and height, the 1.5 inch that Mac is using would be the way to go. I also find that raising the speakers off the floor improves bass.

I'm using a set of the non-threaded Giant Gliders under an isolation shelf. The speakers with the threaded Giant Gliders sit on this shelf/Glider combo.

@david_ten I was thinking taller feet as well as I had similiar results with some large Jamo Cornet 100's back in the 90s. There were no feet, so used brackets and JB weld with threaded rod and caps, a college upgrade. Bass tightened up nicely. 

Your comment on doubling up the isolation with shelves and additional gliders had me recall the Townshend isolation speaker platforms. The price has me looking for other tweeks. Is your isolation shelf basic mdf or something fancy?

What are those speaker stands that @teajay uses? I forgot. I should have bookmarked the site.
