Dear @enginedr1960: Yes, always near field live MUSIC is the perfect REFERENCE for audiophiles and yes listening to other audio systems ( as many we can. ) always helps and is a main part of the audio learning curve.
Yes, there are not only " so many variables " but I think that are to many and we have to live with more trade-offs that what we like it. The audio and especially the analog experience is way imperfect and through those imperfections is where the trade-offs are generated and the critical issue here is each one whole abilities to choose exactly the ones that overall does less harm to the MUSIC enjoyment.
All those is a continuous quest to be " there ", it's a continuous day by day learning till we are really/true satisfied with.
Always a challenge for any of us and that's why many of us are buying new audio items ( cartridges, tonearms, cables, TTs, electronics, speakers and the like. ), we mantain this kind of behavior always looking for the " new kid on the block " and we can't stop to do it ( and always we found out some fun in that looking of " self satisfaction ". ) and we can't stop because our system is far away from that elusive " THERE ".
Take a look on some today threads where even people with what we can think " dreaming audio systems " the owners ( wealthy ones. ) are buying all the new cartridges ( always. ) and everything on the topic.
All those gentlemans have a problem: they don't even imagine that their audio systems are really aways to be not " perfect " but not even near that perfection. Many times their systems are even several steps down yours or other humble systems.
When I came for the first time at Agon ( many years ago. ) I started to post several " new " topics/audio subjects that ( like even today ) gone against what almost all audiophiles learned through their audio lifes. They treat me as if I was some one with out experience and no understanding of what surrounded the audio experience.
They ask several time that I disclose my audio system and I did not because I thought it can't help too much but finally I did it and many gentlemans said: wow ! . They thought that I was an audio items collector with out understand the why's of that and today ( almost same. ) system.
The real subject was that even on those " old " times I was near that " there " and needs not any more to look for the new " kid on the block ". I already passed for it and after that
I " only " was an am fine tunning very fine tunning the same system and today I'm almost " THERE " and the level of MUSIC enjoyment is something really dificult for me explain it.
Today I'm not even for curiosity to listen this or that new item " designs " because in reality exist no true " new designs ": " new " tonearms are more of the same, " new " cartridges are more of the same, cables too and TTs/everything. Exist nothing really NEW. No single audio item shows something real better but only different ! ? ! ? ! ? !
Have fun been truer to the recording.
Regards and enjoy the MUSIC not DISTORTIONS,
