I was prepared long ago about this drawback ...
The title of my virtual page in the last 10 years is : "Audiophile experience for the poor"
I discovered that the three embeddings controls : acoustic, mechanic and electric, put us far enough on the road to claim audiophile results at low cost...😊
Add to this synergy between the right vintage conmponent and you are there...
What amplifier can beat my Sansui alpha today and at which cost ?
Good luck... It will be way costlier...
For the Akg K340 , to beat it buy an Abyss or a Susvara...
Now add the cost of a new amplifier and of the susvara and you exceed easily 10,000 bucks versus my 700 bucks...
I know for sure that i enjoy music with a very good sound... No need to fool my brain .... Upgrading will for sure be possible...
But as i said there exist a MINIMAL audiophile threshold of satisfaction ...By objective as subjective criteria together...
😊
The only drawback is membership in the prestigious high end audio club will be harder to earn, so better get busy right away on that one.
