Quad 2905 versus Quad 2805 plus subwoofer

I have owned a pair of 2905s for nearly 6 months. Properly setup the bass is awesome not in the Wilson Watt Puppy way but deeply satisdfying. By setup I mean apart from placement, the speakers should be rock steady using the supplied spikes.I would love to hear a Quad/Rel combo but suspect that some element of smearing can't be ruled out given the relative differences in the speed of the REL driver and the ESL diaphgram which is ultra fast. Anyway its an interesting idea and am really curious how you get along.
All the best.

I need to update my earlier post( March,2007) in which I had mentioned some reservations/doubts about pairing subs with the 2905s. I have been running my 2905s with a pair of REL 505s for over 5 years and couldn't be happier. There are absolutely no issues regd. smearing etc . My room is approx 14'x23' with a 10' ceiling which opens into a smaller 400sq ft space. If at all I would like to upgrade the REL 505s to the G1s.
Cheers
