I have read a lot about this speaker, and i studied it's ribbon design. It has an excellent ribbon suspension designs and very good engineering and i very much wonder, why it (the drier itself) would need 'smoothing out'. I know the Maggie QR designs and the Ambience ribbons intimately, and the B-G and other drivers too, and i think my guess at the potential of the drivers is well based: It is an outstanding design and has the potential to sound this way too - at least in the upper ranges :-)
The crappy part in the design of the speaker seems to be at least the transformer used for the ribbon. If you want the best and are willing to pay the price: www.audio-consulting.ch for a custom transformer design. Or do a search. The transformer is severely substandard in this speaker and creates distortion, which was measured for Hifi News and Record Revview by Martin Colloms. The ribbon itself is most probably close to perfect.
Most probably the crossover design is not - but that's a never ending story.... if you understand it completely you'd be the most sought speaker designer!
The one thing to look at is the crossover parts: Auricaps and Jensen foil coils will help very audibly, also in the bass.
You'll live quite happily with a new transformer and the crossover updated. Celestion is probably quite willing to provide you with the crossover circuit diagram.
