For (nearfield) listening the ABH2 will be the best. And, the transparency will enhance the ’British roots’ of the Harbeths as pointed out above whilst keeping tight woofer control. Oh, be sure to get the inexpensive Benchmark Media cables especially if you are in a home office environment with I assume with computers and so on. Finally, it has the best volume control of the bunch - 0.5db increments. Makes a soundstage difference. BM has a 30 day money back trial and no-one sends them back.
Which preamp are you using? You can tailor the ABH2 to the source output. It runs cool and sounds like it is not there.
