How often should you re-calibrate your ears?

Yes in deed. And if you can situate yourself right in front of the mixing board in most cases you'll get the best sound. We did that at www.magmusic.com just this past weekend for some truly great american roots music. And the absence from your system for a few days makes it sound even better when you get home.

Nrchy is correct. Live performance and recorded music are two completely different things, from an auditory standpoint. Audiophiles have a false sence of real if they think that what they hear from their system is a live or real sound.

I stand before live musicians every day. From my observation, live is certainly not the same as what comes from my system every night.

Recorded music is so much more controlled than live music. Even recordings made from live performances have more controlls put on them than one tends to realize.

It is simply my hope that music lovers, not necessarily audiophiles, will continue to support live performance. Without support, live performers will cease to do, what it is that they do....perform. :-(

I try to get out at least a few times a year to experience live music. Live is live and IMO no amount of money can buy a Hi Fi system that can equal the live experience. Last year I went to a Jazz concert and the next day I visited a local Hi Fi dealer who had a system set up worth about $150,000.00. I heard a CD played on that system of the Jazz group I had heard the night before and it was NOT the same. It seems to me that once a recording is made something is just lost in the process and no amount of money worth of high end audio equipment can bring it back. The biggest difference I noticed was with the drums, especially with cymbals. They just had such a sweet metalic shimmer that was NOT there when the same recorded CD was played back on even a system in excess of 100 grand. It's like comparing a photo of a certain place or event, just not the same as being there.

We may be missing the point RCPrince made ...

NJPAC/Avery Fisher/Carnegie are concert halls playing UN-amplified, live music where your ears get to hear an instrument without any mixing board in the way. I would think this is in fact, a reference - even though we all do not necessarily like classical or "pop" music.

Listening to any amplified music thru a mixing board and amplifiers/speakers etc is, as has been pointed out above, not a reference at all. In these cases we are subject to the choices made by the mixing engineer, and the effects of transmitting and amplifying the music electronically (even when standing right in front of the mixing panel).

most every recording is meant to sound like a recording. even most live recordings are remixed and overdubbed.
