@soix I have 803D4’s (not D3’s) but you are correct about the upper registers. I’d like as much imaging, 3dimensionality and life like presentation as possible. I find magic in the small details and how notes can hang in the air.
@audphile1 I would consider a Ref6 SE but (maybe because of my lack of knowledge) thought it would be best to buy a pre amp which has Home Theater Bypass as 60% of the time the system is used for that.
You can turn the Backert off for HT , also it’s much more affordable than the VAC. Have not found a store that had both so I can so listen side by side.
