As much as some of us like to flatter ourselves as Super Experienced, the wisdom we have built over the years tends to be most relevant to ourselves and our tastes (and perhaps for those that share that taste). It’s not discovering The Secret Key Of Satisfaction for others.You are right speaking of taste and choices of gear....
But there exist simple practical facts which can tranform the experience with any gear....
How to embed a piece of electronic equipment in a relatively controlled mechanical, electrical and acoustical dimensions ?
This is all i learn along my way.... Others will suggest better ways to me that those one i created for myself, but these 3 embeddings are key and NOT secondary problems ....
For any choice of gear you are right....
Nevermind the gear, or forget upgrading before embedding anything right....
This is what i learn and say.... Very few really know this transformative truth and experience and experiments on all forums....They all speak of their last or future upgrades....Without knowing.....
