My personal preference in the Meridian DSP range of speakers is for the DSP33. I used to own the M33's and their short comings are addressed by DSP in the digital version. I've had the pleasure of visiting the Audio Images where they're used most effectively in quite a large (and very beautiful) dem room.

The Meridian data sheet for this product mentions some of the on board DSP processing that is used to adjust the natural (passive) frequency response. Being a small speaker the DSP will be relatively limited, I assume in the 8k's the processing is far more complex...

"The unique Meridian DSP processing is performed on a brand new 100 MIPS Motorola DSP, the 56364. Like the other members of the Meridian DSP Speaker family, the DSP33 Signal Processing includes

� FIFO memory buffer input for the lowest possible jitter from almost any source
� Linear-phase crossover for precision drive unit integration not possible with analogue techniques
� Tweeter delay for perfect driver alignment
� 48-bit resolution volume control
� Minimal frequency equalisation to give a frequency response free from drive unit or electronic colouration
� Transparent tone controls
� Absolute phase control and phase-corrected balance control

The extraordinary big box sound of the DSP33 is achieved using exciting new signal processing developments. Meridian�s active bass extension deepens the response without excessive woofer excursion. At moderate volumes, a psychoacoustially correct extension filter extends the bass still further.
At high volumes DSP bass protection helps prevent the woofers from bottoming. Only the very lowest frequencies are reduced."

When watching a movie and using a system in home theatre mode the brain devotes far less attention to the audio quality. As such, I'd be very happy to have a DSP33 equipped home theatre. However, for two channel I prefer the presentation of the Quads and the unique intimacy that electrostatic panels are known for.

The 33's would be supported by multiple subs placed to minimise resonance excitation in the room. The B&W PV1 is a superb design, again port free - it's only a shame they don't accept a digital MSL input!

If the Quads timing circuits could be controlled by DSP rather than by passive components I'd certainly invest further as the DSP would certainly be the lesser of the two theoretical evils.
