Congested sound - more power or resolution?


My sound has improved markedly with the upgrades I have done. One part of my music collection still isn't right though. Previously at higher SPLs all music got bad slap echo and bright, room treatment has sorted that out.

Now with some tracks mainly rock with guitars especially, the sound gets congested, image is lost and it gets grungy. Have I met the limits of my room, or with more power would I have better control of my speakers under a lot of stress? Or would a better quality spinner give more improvement through better resolution in the first place?

My system in in my signature, but breifly Arcam DV27, Meridian 861, Krell Showcase amp, Wilson Sophia.

Both player and power amps will get upgraded, I'm just trying to prioritise my budget.

It's not the room and although one component or another may be contributing to this grunge to some extent, you are probably experiencing the results of untreated AC noise and the bi-directional digital noise generated by your cd player.

Digital noise is bi-directional in that the noise it generates goes back into the AC line, even back to the service panel, and in then infiltrates into your other components.

Before you do anything with your equipment, you should investigate proper line conditioning. I say proper because there are plenty of popular line conditioners that do nothing and worse. Furthermore, some to many line conditioners do not have bi-directional filtering capability.

Once you have acquired proper line conditioning, your system is now resting on a solid foundation, eliminating any grunge or digital hash and therefore should be far more pristine and musical. As a result your present and future components will be exhibiting more of their true potential.

Also, keep in mind that some to many ics and scs induce a time smear that will also sound like a grunge or digital hash.

Dmurfet, your specific issues / concerns could be one or a combination of problems. Still I find your response about line conditoners interesting but not surprising.

My initial response is, what is your experience with AC line conditioning?

You are correct in that some very expensive and beautiful systems have no regard whatsoever for line conditioning. And I'll also bet dollars to doughnuts their systems are experiencing much the same deficiencies you note above.

That's because AC noise is very real and universal and we all have it to one bad degree or another. Furthermore, digital noise is also very real. All this noise left untreated will leave virtually every system sounding fatiguing to one degree or another.

You may have noticed in my first post that I used the term 'proper' line-conditioning, thereby implying that there exists 'improper' line conditioners which are very abundant in the marketplace and often carry very popular name brands.

Sub-standard line conditioners are also very real. There are those that rob amplifiers of necessary current and thereby strip away all dynamics from the music rending it rather lifeless. There are those that do absolutely nothing. And then there are those that, even though they may clean something, they induce their own sonic harm and thus make the sonics worse than without any line conditioners.

With regard to the owners of these otherwise desirable systems, there are those who have never had an encounter with any, much less, proper line conditioning.

There are those who have tried line conditioning but since they've only tried inferior models, they walk away saying or thinking all line conditioning must be bad because I just spent $500 - $5000 on these units and they made my $200,000 system sound the same or worse but not better.

There are those whose systems need so much help that it really doesn't matter what they do.

There's alway those who simply cannot hear any difference no matter what they do.

There are those who own one or more components where the manufacturer (say a cd player mfger) has made their own attempt to address AC Filtering within the component itself. It's usually a half-assed attempt and sometimes with a $5 AC filter that may simply suppress certain offending frequencies. Some of the owners of this type of equipment audition line conditioners (good or bad) and almost always when one doubles up on line conditioning (especially when each employs different filtering methodologies) the end result is almost always disastrous.

So again they walk away saying or thinking all line conditioners must be bad or of no value.

And finally, there are those have acquired performance-oriented line conditioners and fully realize the significant gains that proper line conditioning provides. So much so that rarely is there a system worth listening to that does not have proper line conditioning as part of their system, regardless of the price of the system.

Given the above (assuming it's true), is it any wonder that an enthusiast or reviewer wrote that line conditioning may not be a good thing? Given the sub-standard performance of some line conditioners, the author is correct. But in the end that author is no different that one of the siutations I described above.

I can pretty much assure you this: If you did install 'proper' line conditioning in your system, (and barring any other potentially serious deficiency you may have) your system's sonic performance and ultimately your listening pleasure will meet or exceed almost every one of those very expensive and beautiful systems that use inferior or no line conditiong.

At least your equipment is certainly capable.

Matrix, yes, there are some (actually very few) components built far beyond other's power supplies as you stated. In fact, though there are a few out there, I only know one by name and model and that is the APL modified NWO-1 Esoteric ucdp. But even that unit may not contain much in the way of correction.

On the other hand, it does not appear that you or I have any such components in our inventory. If that is true, then AC noise is definitely a problem we must contend with if we hope for a pristine, musical presentation that also does not induce negative sibilance (when it's not in the recording itself).

And though dedicated circuits/lines are also a necessity, they exactly two things that I am aware of:

1. Help ensure that power supplies, particularly amplifier's, receive the nessarity juice to reproduce more fully reproduce dynamic and/or complex passages.

2. Minimize or eliminate AC noise that is generated within the house such as dimmers, appliances, etc..

But dedicated circuits/lines do nothing to cleanse the AC noise coming in from the street. That is why 99.5% of us are in desparate need of 'proper' line conditioning.

And that is why I made my suggestion to you in my earlier post regarding 'proper' line conditioning.
