New SS integrated choice....Rotel 1572Mk2, Audiolab 7000A, Exposure 2510

OK, got sick for awhile and off course on buying a new integrated to replace Marantz PM8005 to be moved to office. Looking to upgrade my sound quality overall.  (Was looking at Belles Aria but got off the record feedback units have been having some higher than average issue rates so I am moving onto other options.) Reviews online got me focused on 3 in particular, none of which I have heard before namely Rotel 1572MK2, Audiolab 7000a or 9000a and Exposure 2510. First two are readily available and I can get shipped to Hawaii free which is attractive as it saves $150-200. I want new because it ups odds of satisfaction especially as no techs in HI. Will drive Kef R300s or Ohm Walsh 2-100s in 14 x14 LR with arched 9 ft ceilings rising to 20 feet. Looking to keep costs below $3k new. I dont know what the "British" sound really means...only have heard Rega Brio which was fine but sideways move. Interested in feedback from anyone familiar with these brands, sound characteristics, reliability, etc. Aloha.
