resolution and imaging

As my system has evolved over the years, I've noticed a change in how I perceive resolution. Resolution and imaging now seem inextricably linked to me, in other words, maximized imaging is absolutely necessary to maximizing resolution.

Prior to the last couple of years, I heard increases in resolution the way most reviewers describe it. A lowered noise floor allowed more detail through, I was hearing more background (low level) information than I heard previously.

With more recent upgrades, I now hear greater detail/resolution due to enhanced image density and dimensionality. Each upgrade brings more spaciousness, and with more space between all the micro elements that make up sound I hear more detail/resolution. I would not be able to hear as much detail/resolution without this enhanced imaging.

And so now I hear of audiophiles who claim imaging is not important and/or not on high on their list of priorities. I theorize that without high imaging capabilities one cannot achieve maximum resolution from their system.

I recently saw a thread on holographic imaging, some argue this is not present in live music. I totally disagree, live sound lives in physical space, physical space is defined by three dimensions (at least three we've been able to detect), sound is by definition, holographic.

IMO, audio systems must maximize image dimensionality in order to be both high resolution and more lifelike. While I agree that other aspects of audio reproduction are critically important, ie. tonality, dynamics, continuousness, etc., so is imaging.

My last statement about bad recordings sounding worse may in fact be wrong. My view on higher resolution and sonically challenged recordings has evolved over the years. I'm finding that high resolution may in fact improve the sound of many lesser recordings if that higher resolution is accompanied by a coincident improvement in the other sonic parameters. Lesser recordings can actually sound better than before.

If the higher resolution you're extracting results in a more palpable, organic sound, its all to the good for the lesser recording. I can't think of a single cd or album I've tossed in the past couple of years, I tossed perhaps 10% of my recordings prior. I've returned a number of times to these previously trashed recordings and found new life and interest in them. Perhaps there is no downside to properly balanced high resolution.

Sns, I agree totally with your last post. This has been my personal experience as well. I won't bore with details, but I have so many CD's of great performances (thats why I bought them) that are quite listenable now than I did just a few years ago and this is all related to an honest re-assessment of my real goals and expectaions. I keep digging out these old remastered analog and early digital recordings. Like having a gold mine of new unexpected treasures in the closet. :-) I have not found any that sound worse, or even as bad, as before and the ultimate resolution qualities of my system have made a major leap since I put them away.

I agree that some CD's thought lacking...are now listenable. The increase in overall resolution has given new insight for me into the engineering of the recording. As example...Ampex 300 3 channel recordings are obvious as are most or all recordings where Ampex electonics were used. Interesingly they are among ones I like best....along with Studer 800 series.

soundstaging is not real. when listening to a symphony orchestra from the last row, there is no localization. it is difficult or near impossible to hear individual violinists in the string session. rather one perceives a string ensemble.

regarding resolution. there is a roundness and defocus, when listening to an instrument from a distance. there is such a thing as too much resolution.

as an example, consider a photograph of the human face. 8i am not interested in observing the warts, wrinkles, scars, etc. . i would rather see a smooth face. applying this idea to audio, a defocus control is most useful. it is not a matter of frequency response. it is purely the desire to create a roundness, smoothness and plesantness to the sound of all recordings.

thus, i view a stereo system as an instrument, not a reproducer, just as an artist interprets i want to create a pleasant structure to whatever i hear.

most stereo systems sound very unrealistic and unnatural when compared to live music, and a focus control would be most helpful to redress the discrepancy between live and reproduced music.
