Tekton Double Impacts

@almarg Ha, no, thank you Al.  As always, great information.  The Franks just provided very little bass output on the PREs.  My Super Eclipses (2 8" woofers going down to 28Hz) provided way more bass than the PREs (2 12" woofers going down to 20Hz).  Unfortunately I never got to make a real decision about how much I liked the PREs since they always sounded unbalanced without any real bass output.  

I was considering passive bi-amping because it just felt like limitation was just with the Franks driving the subwoofer units.  

Anyway, sorry for moving the conversation outside the DI topic.  I appreciate all the useful commentary... great thread.

mac48025,

Al and grannyring are spot one with their advice,

I have measured my DI speakers in room and I got,
95.3 db with a 1 watt input at a distance of 1 meter at the industry standard frequency of 1 K.
 
Even though both of us have definitely enjoyed the 1 watt of our MZ2S driving our DI's It's just not enough pwr for me overall considering my room size,types of music,and volume levels.

I got some new tubes for my Yamamoto Ao9's which is a 8 watt per channel 300b pwr amp for those who aren't familiar with it.So in the next few days I will be seeing for myself how it does with my DI's in place of my Zotl40.

Speaker and amp pairing is highly subjective as grannyring mentioned and It's up to the individual to find his or hers cup of tea so to speak.

Mac,
If you and I can ever coordinate our schedules I’d bring my Frankenstein (with its 8 and 16 ohm taps) and we can simply listen to how they interact with your DIs from their 8 ohm tap. I’ll be back in Michigan in a few days.

Cal,
The Frankenstein works wonderfully with the Coincident Eclipse line of speakers and their Triumph Extreme monitor speakers. It seems that the other Coincident speakers need the Coincident Dragon mono blocks or suitable amplifier with more than 8 watts. I truly believe that the Line Magnetic 845 or 805 tubed SET amplifiers would be excellent with your Coincident PRE speakers.

If Mac and I are able to get together I’ll surely report to you how the Frankenstein and Double Impacts fared as a pairing. Grannyring (Bill) you’re right, this is all about subjective preferences. I do believe Terry in that the Double Impact and Triode Labs sound better than "any" other amp/speakers match he has heard in his review/main system and this includes many fine audio products over the years.

Hi Charlies,

Please remember that I just ran the experiment of driving the Triode Lab SET 2A3 amplifier with a very good tube based preamplifier through the Ulf's and this combo was very good, but did not have the ultimate magic of the combo of the Micro-ZOTL/2A3.  Yes, for me the 2A3 tube is even more natural/musical then my old favorite 300B.  However, the Micro-ZOTL adds the overall kick/dynamics, pure tonality and 3D imaging and the 2A3 adds the colors and even more air and space between players.  One more time, on either the DI's or Ulf's, regardless of the type of music, I can shake the walls and pressurize my very large acoustic with ease.

Just submitted my order for a pair of Electrons this afternoon.   Cautiously hopefull.  Would have loved a pair of double impacts, but their visual/size dominance is just too much for my room.  Praying the Electron will approach the level of play reported here.
