Tekton Double Impacts

Just because 1 watts seems to work doesn't mean it is "best". I don't see how you can say that 51 watts is overkill. From a physics standpoint, this makes no sense.

There's another way to look at power and the DIs. Eric specifies the power handling of the speakers at 400 watts. That's what I use to judge how large an amplifier is required.

@porscheracer - I agree now that I'm listening to another amp and have a decent amount of headroom.

@mac48025 - I will try out the ZOTL40 next.

Agreed, overkill wasn't the right word to use, but 40 watts certainly isn't necessary with the DI's......that doesn't mean having more wattage is a bad thing either. The ZOTL 10 would be plenty for the DI's, yet Terry London prefers using the MZ2 alone over the MZ2/ZOTL 40 combination and prefers the MZ2 with the Triode Lab 2A3 SET amp the most. Until living with one watt driving the DI's I would have never believed it would suffice let alone outperform the 220 watt SS monoblocks I was using before going to tubes. While the big amps were certainly louder, more dynamic and sounded very good, to my ears they didn't come close to the musicality and realism of the MZ2......especially with good NOS tubes.

Youre right Craig, Eric prefers large SS amps with his speakers. I believe he recommended Bryston to me. I don't dislike SS amps, I especially like the dynamic slam they can provide, but over the years I've gone from the likes of the ARC D400, Levinson 333 and Odyssey Kismet Monoblocks to small tube amps. Eventually I'll have an SS system for HT and rocking out to in addition to my DI/tube system. 

Mac: The power handling figure provided by Eric is not his preference; it is the result of the drivers chosen and his computation of those drivers sounding within the crossover design. It is clear that you like small tube amps and I have read and benefited from your perspective. But let's distinguish between facts and preference. Porscheracer is correct in referring to Physics and Eric's specifications are facts.
