Harbeth 7es3 vs HL5

Does anyone have a recomendation between these 2 speakers for a Rm approx 20' by 20' opening up to a kitchen and dining rm about the some size. I currently have Dunlavy 4a speakers which are untamingly bright. I have several tube and solid state amps and different speaker wires. The accustics are very difficult to deal with realistically and there is no long wall for the dunlavy's. I guess what am asking is would the 7es3 be too small for this size rm.I do have a sub if absoluely needed but I am no bass addict but am looking for a natural midrange sound. Thanks
