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?

" If it is clipping on rock then it will clip on jazz too... "

Wrong.

A primer on clipping and other challenges in faithful reproduction of musical peaks was written by Simon Thacher of Spectron and published in EnjoyTheSound:

That's a nice article.

My technical intuition tells me that fast and highly efficient Class D switching amplifiers like the Spectrons or Icepower are tailor made to accurately address the issues associated with dynamics, transients, and clipping better than conventional SS or soft clipping tube amps. What I hear on my BelCanto ref1000m Icepower monoblocks support that. For my application and speakers, in that I want realistic dynamics and transients as much as possible with minimal fatigue causing distortions, none of the power or current available in the ref 1000ms are optional or unneeded I believe. The OHMs in particular are capable of very good dynamics, articulation, detail and and muscle (a tough combo to achieve together) if provided the power needed fast enough and the BC icepower amps have set the bar in regards to that for me.
Food for thought. I recently produced a hard rock album that was master at sterile sounds in NYC. We sat in with the engineer and after about 4 to 5 hours of listening to the same few songs we left. In the mastering studio is sounded awesome, like yes right there drum hits perfect, guitar loud and controlled.

So we get in the car modest stock car stereo sounds terrible.

So I bring it home and put on this one song and on my Primare I normal listen with the volume on 25 or 26, 40 is half. Well the recording was so HOT is blew my right tweeter and just before it blew the sound stage just disappeared. So as much as I want to agree with MAPMAN that there is never anything wrong with the recording this makes me disagree but at the same time under powering a speaker is just as bad, so what it comes down to is process of elimination. I don’t think either one is a 100 true argument.

Oh MAPMAN DEATH MAGNEGTIC Metallica’s latest album play that and report back. Oh and don’t listen to the one from Guitar Hero it’s a different recording, there are bootlegs around of that one.

Ted Jensen doesn’t even what credit for mastering that one LOL
TGE,

But you say it sounded good with realistic dynamics and loudness in the studio, right?

So the recording would not seem to be the issue. Sounds like your amp clipped and blew the tweeter. Clipping is usually the case when a tweeter blows. Loud, dynamic passages are usually the culprit.

When I used to sell audio years ago, with vinyl as th emain source, many more tweeters were blown by 15 or 20 watt amps tha 80 or 120w/ch ones. Warped records in particular were problematic in that the low frequency noise created used up the power and left the actual music to clipp fairly easily. This is not an issue with digital and I believe fewer tweeters get fried these days in practice due to clipping with digital sources, even though clipping is still a common occurence and affects the sound quality otherwise..

Overdriving a speaker with too many clean watts without clipping can occur also and limit or distort the sound perhaps somewhat, but damage to the speaker is less common than when clipping occurs.

I'll try to check out the Metallica. The Metallica I do have (S&M, Metallica Black album) finally sounds about as good as it can sound these days since moving to the 500w/ch Icepower "monster" amp.
