Urbie, the reviewer at 10 Audio has very few known reference components that one would normally compare any component to, his opinions are interesting but no more valid than any other reviewer.
His rating of components is based on what sounds good in his setup, and sometimes, a particular components or loudspeaker may require you to change certain items in order to make that particular component shine with the rest of the components
If you understand the industry, and have experience there are two types of loudspeakers.
Many people in the industry refer to an easy to get a particular loudspeaker which sounds good in many setups a drop and plop, kind of loudspeaker.
Loudspeakers which tend to sound "musical" Vandersteen, Harbeth, Verity Audio, many Sonus Fabers, Vienna Acoustics, these speakers tend not to have the ultimate resolution but are always enjoyable.

The very high resolution camp are way more critical of setup in order to get the speakers to sound magical, Radiho, Persona, Rockport, etc.
One could argue that you shouldn't have to work hard to create great sound, however, the same argument can be made with any truly cutting edge product that doesn't hold back.
If you are driving a Porsche 911 Turbo you better make sure if you are driving the car at the track with very high octane gas and your tires are properly inflated and balanced, at 60 mph you wouldn't notice, at 160 mph any difference in inflation, or balance or lack of correct octane and you will not be driving the car without having a very different experience.
The Personas are quite magnificent when they are setup correctly when they are not they are as you describe.
