Which amp of these two is best for the Elac Debut Reference DBR-62?Edit: Prerequisite, starting point that the amplifier is able to reproduce the signal as linearly as possible together with the speaker in question.

In this case, remove the amp power (or rather start from the test below for Aiyima, i.e. power supply: 32 volt, 5 amp switching power supply) as a part of the equation.
Just consider how these amps handle the Elac Debut Reference DBR-62 best.


An older NAD amp but based on the results in Amir's test:

How should one interpret the measurements in these tests in order to determine which amplifier can handle the Elac Debut Reference DBR-62 best? Observe in reality? FR deviations is the most decisive criterion.

I see FR deviations in these cases as the most problematic part. Or do both amplifiers handle FR deviations equally well?

"However, note the area I have circled. Impedance is high at about 8 ohms but the phase angle is quite acute at nearly 50 degrees. This means the speaker will ask for current when the output voltage is very low. So you better have a beefy amplifier to drive this speaker."

Selection of the Elac Debut Reference DBR-62 made because it is a (the most? ) recommended speaker on the ASR.
