Sad news, although I'll admit to not going in their local store any more. Nothing there for me, the jazz racks seemed to shrink more at every visit. I've bought one or two things online when the price was right but the jazz inventory was never that good. Nevertheless their presence on the High Street will be missed.
Then there's the nostalgia, the record label (Impulse albums came out in the UK on the HMV label) and years ago there was the wonderful shop at 363 Oxford Street.
