Paradoxically , i owned my Tannoy dual gold concentric mallorcan , paid 300 bucks in 1976, for 45 five years... I even owned two pairs... In case...
They were more than good...
But Alas ! I sold them 1000 bucks each pair ( they now sell a few years later 3,500 bucks ) BEFORE I LEARNED SMALL ROOM ACOUSTIC... Then i never listened to them really at their real peak potential at all ...
😊
Now i am in headphone by fate , which are so good when well optimized , i console myself...
Lesson one :
Nevermind the speakers you own, it does not matter so much as you think ...Even if they are good for the "long haul"...
Lesson two:
You dont know them if you have not put them in an acoustical environment for them..
Lesson three :
Most headphones for me are bad compared to speakers , even to speakers in a living room in many case... Then stick to your speakers and think about your room ...
Alas! i dont advise to buy an AKG K340 , because it takes me 6 months of experiments before being satisfied... A complex technology to handle well...
Audio is acoustic knowledge not brand gear knowledge...
