Not less than probably 200 watts. I know the number is somewhat abstract due to design,
Not jumping on you here so please do not take it that way.
The perfect word in your sentence is
"NUMBER". It is JUST a NUMBER and it does not define, convey, or tell what the product is capable of doing in the way of sonic reproduction.
To base one's choices
PURELY ON NUMBERS is back-arse-wards. The number game is just that, a marketing number game. If someone is looking for very high SPL reproduction along with maintaining sound quality and has the need to listen to music at 100-120 dB's, then the numbers game may become an issue. (The HT geeks are very staunch on their required SPL numbers for subs)
other component compatibility and synergy, manufacturers claims, testing methods etc., but a mid-fi quality product of around that rating.
So less than 200 is "mid-fi" quality? Maybe I did not interpret correctly what you were saying here. Or are you saying with Mid-Fi anything below 200 is not as good as something above 200???
I've tried less and the speakers just are not as alive without it.
Okay, I respect your subjective opinion on this. You need power to make the sound come alive. Do you prefer you music at a louder level?
There is lots of detail, but the presence is lacking. I also know that if you move up the quality chain sometimes huge sonic differences prevail, but also the realism of cost comes into play.
Don't follow you on this: Detail but lacking presence? Do you mean the music and all the details of the instruments are there, but you are not feeling it??
Quality Chain: "Sometimes" is the correct term, as cost comes into play with everything we purchase, not just our beloved audio toys. Cost does not always equate quality.
As much as I lover the hobby, it's isn't a bar-none, end-all money pit for me as that game has no end.
And I believe most of us here are in the same boat. Some have a larger boat and some have a dingy, but we each have what we own and love it. So to categorize or stereotype a component based on numbers is completely wrong in my opinion.
BTW, my lowly, POS amp I use falls way below the 200 number you have proposed for discussion here.
Dave, Joey, Kevin, etc. looks like it is time to sell....
