Is this clipping?


I listen to jazz music mostly, using a 10 watt SET (300b) amp and a pair of high efficiency single driver speakers. Sounds great at any volume with any and all jazz. But when I try to play HEAVY rock music loudly, it sounds like a completely different system: The soundstage flattens, instruments blur, and dynamics are lost.
We all know that a system like mine is not intended for certain types of musics, but I wonder what is the main reason for this behavior. Is it clipping? Is it a characteristic of this particular type of tube or amplifier? Or is it a charateristic of full-range drivers like Fostex, Lowther, PhyHP?

Unsound,

My experience over the years has been that most all rock/pop recordings suffer if the system is underpowered or undersized, among other things. The ultimate quality of these compared to others on the grand scale of things doesn't matter.

Whatever their other issues on the grand scale, the newer louder pop/rock digital recordings out there are more challenging from a power perspective, not less. I think it just follows that louder requires more power to reproduce accurately, for better or for worse.

Modern rock pop along with perhaps big band and large scale classical are exactly the types of music I would expect a flea powered SET running single driver full range speakers to demonstrate limitations with, at least at realistic volumes, although this kind of setup should sound heavenly most of the rest of the time.

Play the drum intro to "Know Your Enemy" By Green Day for example. WHen the song starts and the drums hit, they should sound very real and knock you out of your seat. Other than that, the recording is acceptable for what it is, but nothing special by any stretch otherwise.
Mapman, the way new pop recordings are made, more often than not, leads to the lowering of volume, even in high powered systems, negating the very benefits of high power. These recordings are made to facilitate lesser systems that amongst other things, don't have the power to handle true dynamic contrasts.
Well, if the system is clipping as a result, the results will not be good, that is for sure!

Overdriving the speakers won't help either.

Both together is the double whammy.
Overdriving the amp = clipping. Overdriving the speakers is something else. Either way you stand a chance of damaging drivers.

Many audiophiles believe their tweeters are not in danger with tube amplifiers because they clip so graciously. This not so.

Overdriving the speaker results in damaged woofers.
