Take a look at Srajan Ebaen’s 6moons audio reviews. For example check out his speaker reviews for the Cube Audio Nenuphar v2 and Qualio IQ. Two speakers made by the same principals that have two different approaches, requiring different considerations, and resulting in very different amp choices. He’s very good and consistent in his review approach and you can glean a lot of useful information from them.
I know stylistically he’s not everybody’s cup of tea, but if you can get past that, then there’s a wealth of information on offer.
