Spendor Bc1 what is a good upgrade mod ?

I have a chance to get a pair of B&W DM 620i speakers , would they be a good alternative to modding the Spendor BC1 ?

I am still looking at a pair of TDL monitors , due to the same type of drivers , a bit like BC1s on steroids.I dont think i will sell the BC1s whatever i end up with , i got an e.mail from cicable.com regarding the BC1 crossover upgrade and the price was through the roof so Marigo VTS bands could be the go , the BC1s will only go for loose change on the used market so whats the point , they still sound great with more laid back music and also i have discovered they sound much better with vinyl than cd but i guess thats no surprise :-)

Hi John
Thanks for the e.mail and advice it is much appreciated , the hifi shop where the TDLs are for sale is a place i have been dealing with for some time and the owner really seems to think that a more modern design is the way to go , i can see his point but hey the BC1s are a lovely sounding speaker so the TDLs are not to be overlooked , it could be for a sale figures but i dont think he would go this path as i have been dealing for many years with him and he see's me as a client more than a blow in of the street , its just hard to depart from the warm Spendor sound , i guess its like an old friend , i will post what i decide .
Cheers. Phil.

They have been sold so i may look at NHT ST4 or Triangle ?

How about the B & W cdm nt 7 floor standers ?
