Tekton Double Impacts

What is the law of physics and "facts" that proclaim that the High power transistor amplifier will sound superior to the low power tube amplifier? There is no such law or fact. What is true is each genre of amplifier has its strengths and weaknesses and individual listeners ultimately choose what suits them best
Teajay clearly preferred  the 3 watt 2A3 SET Triode Labs over his Pass Labs XA 60.8 amplifier. I strongly suspect that Craig and Porscheracer would opt for the big Pass Labs. Each of these fine amplifiers have unique attributes to offer and will obviously attract different groups of listeners.

I would choose as Teajay, nothing to do with physics, rather plenty to do with how we hear and interact with music,. This isn’t a right or wrong choice, it is everything about how people listen and what they key in to,.

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.

I would respectfully but emphatically disagree with the use of the word "required." A more appropriate interpretation, IMO, would be that the specification of "400 watt power handling" provides a rough ballpark indication of the maximum amplifier power capability that is recommended as being reasonable for use with this speaker.

Also, as Mac alluded to, for a given amplifier type and topology it can be expected that everything else being equal more amplifier watts = more amplifier $. Therefore for a given amplifier budget paying for watts that will not be utilized would in general mean that a higher percentage of that budget than necessary will go toward watts rather than sound quality.

One of the reasons I chose my Daedalus Ulysses speakers, which like the DI have a very benign impedance curve, fairly high sensitivity, and high power handling capability ("recommended power 5 to 300 watts, peak power 600 watts +") is that I wanted the majority of my amplifier dollars to go toward sound quality, rather than watts. And even though I frequently listen to well recorded minimally compressed classical symphonic recordings which reach brief dynamic peaks of close to 105 db at my listening position, I have been very happy with my 70 watt VAC Renaissance amplifier. And perhaps its 30 watt smaller brother would even have been suitable as well, but I wanted to be sure that the margin between necessary power and power capability would be comfortable while not being excessive.

The implication seems to be that because the DI can accommodate up to 400 watts this means that this is the preferred or optimal power requirement for this speaker. There is also  the skepticism raised concerning the adequacy of 1 watt of power driving the DI despite the (by now) numerous testimonials by owners who attest to this outcome.

Again as I have written previously in this thread, clearly the DI is quite sucessful paired with amplifiers from one end of the power spectrum to the other. If my inference to the several posts above is misguided then I stand corrected.

Hi Al, You posted while I was still typing 😃
But yes I picked up on that same comment regarding speaker power handling capability. As usual your point was well made. The"required" used by Craig was not factual IMO.
