Well when the harbeth 7 were in your to big list would you consider the smaller model? Also you might want to look at the neat speaker line. I would start at the motive line not the iota. You can go up from there as well. If I am correct you have both a tube amplifier and a solid state. Are you thinking I biamping these new speakers? Tube running the top and solid state running the bottom? If that is the case you need to find a speaker with two sets of binding posts. Also you might want to think about a pair of ls3/5a speakers from one of the manufacturers that build them. Thinking about that is the same as the small harbeths. The smallest pair of made in Italy Sonus Faber speakers would likely be wonderful as well. Does totem still make the model one speakers? Those and the Mani twos were in my opinion the best that they made. Mani two s you would not need a sub! They are small but might not work for acceptance factor. I have a set of dome phase standmounts they might be to big for you they are about Beauty. Tonal richness and great tonal balance. The importer here has a set new in a box he was clearing out they were 5500 Canadian retail. Lol no one will know what you have almost nothing online about them. I would bet you could get that pair for your budget. The thing with speakers in my opinion is they are highly personal likely the most personal decision in setting up a HiFi. I have a friend who always said there are larges numbers of speakers available and very few good ones. I would agree with that. I would agree with your list of what you don't like and would add to that! Lol.
