Hi Dracule1,
Yes, there seems to be a thought collective out there subscribing to the notion that accuracy equals a ruler flat anechoic frequency response from 20Hz to 20 KHz.
Objectively this may be true  but there is a world of difference between what is measured in an anechoic chamber and what we actually end up listening to.
For one thing, and as you point out, our listening room acts like a big tone control. Many audiophiles are not aware of how badly their room damages sound quality. No matter how much one has paid for their loudspeakers, amplifiers and source and regardless of their published specifications, as soon as you put them into a typical living / listening room they will exhibit a horribly skewed frequency response. Without some form of correction, much of the sonic benefit therefore derived from more expensive hardware can to a large extent be masked by poor room acoustics.
For another, while our listening rooms are non-linear [with some exceptions like the terrific work of Stereotaipei] so are our ears! Not only are our ears less sensitive at frequency extremes they are also more sensitive in the 2-5 KHz range and have maximum sensitivity at around 3-4 KHz.
For these reasons I earlier wrote that criticizing the performance of a loudspeaker solely from a review of select measurable parameters is a bit like writing a restaurant review directly after reading the list of the food ingredients .
To your second point, yes, the Raidho D-Series is special. They are unique and by all accounts they are selling very well. Last weekend both Lars Kristensen and Michael Børresen of Raidho Acoustics were in Singapore to exhibit at a modest local audio show. Sales for Raidho have climbed rapidly in Asia so it was no surprise to see them both present. The Raidho D-1 held centre stage in a massive 110 square meter room and judging by the post show commentary was very well received by patrons.
I was also pleased to meet Sabai at the show. He was collecting new RaidhoÂs to replace his Joseph Audio Pulsars.
