Just to be sure:
1. Are TRS inputs regular 6.35 mm (1/4 inch) stereo female jacks? All the information I have been able to collect in this thread and elsewhere refers to TRS inputs but does not mention whether they are 6.35 mm / 3.5 mm or stereo / mono
2. What is the input voltage used in Amir's measurements? 0.5 V?
Yes. Normal 1/4" headphone jacks. 6.35mm. Nothing special, but incredibly inexpensive, reliable and strong.
The input voltage Amir fed for the 5W@4R test would have been ~500mV. For rated output, I believe 2.5V (2500mV) is needed.
