Opinions Needed: Hales vs. Tannoy


I currently have Hales Revelation 3 in my two channel system.  They are powered by a Krell KAV 400xi integrated amplifier.  

My question is whether a switch from the Hales to a pair of Tannoy D700 would be an upgrade or just a lateral move.  I’m looking for more authoritative bass.  My complete current rig is listed in my virtual system.  TIA

For god’s sake, if you sell your Hales Revelation-3’s I’m your buyer! The only speaker purchase I ever walked away from that I regretted. Just let me know if you go crazy and want to sell them.

The Hales will remain in my possession in my collection of classic equipment lol
