(...) I recently read this review of a DSP active speaker:
" First impressions were of a considerable achievement, as a result of the time-corrected bass, the smooth phase control, and the sweet sounding digital replay filter, but then some doubts set in. While greatly enjoying it at first, I found that it could not fully hold my attention, and I began to imagine subtle errors, colorations, and frequency imbalances, as excuses to explain my mild dissatisfaction.
It somehow sounded too too polite, even soft, and while there was still much to admire, I began to feel that it also verged on a kind of musical wallpaper. My objective senses fought my emotional response, leaving me in some confusion over the sound of this speaker.
I now recognised some observed lack of dynamic expression as a significant flaw. The sound was somewhat soft and slow with a slight lack of contrast, and I was sure that this was not due to the new apodising filter which had sounded so good when using Meridian’s CD player in a conventional system."
Fortunately just changing the digital input from the Meridiam system to ordinary SPDIF changes everything and the speaker become wonderful.
Considering the shown measurements it seems to me that the great sound qualities of the GBP 17500 DSP 7200 are due to many other factors than just being an active. As said by the reviewer:
"At last we could clearly hear the balance of engineering design guided by Bob Stuart’s view of important psychoacoustic weighted parameters – and it works. " For me this is part of part of high-end and considering Bob Stuart long time credentials and resources involved in this speaker I am not astonished with the result.
