No, there was no reason for me to go back and forth because the impact of the replacement was obvious. The last 4 years (since the time I bought my Forte III) I was trying to figure out how to get rid off some kind of resonance which I had initially attributed to the wooden floor and generally my living room or the placement. I always had hoped that changing into a more powerful amp could help so after reading several reviews of class D amplifiers , I decided to buy the Hypex and connect it directly to my RME ADI 2. Now there is no resonance, it is like everything is more clear and detailed.

Being equally or even more ignorant, I just wanted to contribute to your discussion with my experience. It might be more beneficial for someone instead of getting involved in an endless technical dispute, to go the other way round and do a test powering the speakers with a powerful (at least 100W/ch) amp. Of course ,if you are certain that your Forte perform according to their full potential powered by a 2* 8W amp with any type of music then you do not need to do any test at all. But I think that we should not confuse the gain and the SPL with the power of an amplifier. The transformation of my speakers is much more "obvious" when listening to music at low volumes.

Good morning to everyone. Since the beginning of the year, my Klipsch Forte III are powered by a class D Hypex 2*250W (8ohm) and I can honestly admit that the speakers never performed better in the past. Compared to the class AB 2*50 (high quality) amp I used for the past 15 years, now there is a completely different (neutral) tonality ,much more detail in high frequencies and absolutely controlled lows. Make no mistake. The Forte ,the Cornwall and the Heresy speakers may be efficient according to the specs but their (12'' or 15'') woofer is conventional and not a horn. This means that they need power (the peak power according to specs is 400 W and not 100) and class D provides VFM power. You can have the same result using a powerful AB or A class quality amp (such as Accuphase, McIntosh etc) but not for the same cost.
