Für 2024er Konzepte habe ich mal ein neues Thema begonnen, denn hier geht es ja vornehmlich um den 2020 . . .

Wer oder was ist schon Naim?!Übrigens selbst Naim Audio verbaut jetzt die tripath chips, hier.
Grüße,... We should all thank Adya Tripathi, Ph.D, for bringing the first real amplifier innovation in over 50 years — Class D — into the audiophile realm.
His trick was to pulse the signal almost a million times per second instead of the typical Class D's 100,000 per second. This made it easier to design high quality output filters that have very little effect on the audio band. He christened it Class-T® amplification and introduced the Tripath chip. With the audio fidelity of Class AB and the power efficiency of Class D amplifiers, it was the beginning of an audio phenomenon! ... ©diykits.com.hk
Hi there Jost,
I go the amp today, and i checked the funtion, and yeah its dead... and its the dreaded grounding sensativity of the IC that has caused the logic part of the IC to fail.
Ive replaced the input capacitors on the new board with the ones that where on the old board, and tested the PCB with these caps, and it sounds good!
The new design PCB has much more soldering space than this one, they will be available soon.
ill send the package back to germany the second of january.
Please connect this board as LAST, FIRST connect the source, and then swith on the PCB as last.
if you have any questions, please let me know.
