"Budget" pre tube with SS power amp


I like the idea of have a tube pre amp with a ss power amp. But I know next to nothing about tubes. What are thing to keep in mind when looking for a tube pre that has to work with a SS power. I know some tube pre have an high Output impedance it this a concern? Some tube pre also have some slight DC output. For tube power amps as far as I know this is not a problem but for SS power amps this could spell major disaster as far as I know.

Some tube pre amps that come to mind are the:
Primaluna Prologue 3
Cayin SC-6LS
Melody SHW1688II
Manley Shrimp

The thing is I am looking for some of the tube magic but I don't want an overly warm bloated pre with last of nice fuzzy/warm mids but no low or high to speak of.

So any advise you have is welcome.

I see the VTL has a high gain 20dB isn't that asking for problems with tubes? I also though 12A tubes tend to be warmer then 6299 etc tubes or is that not true?
If you are able to find Audible Illusions in Europe, it would be worth auditioning for preamps in your price range. Other good tube preamps in that range are the deHavilland and Modwrights; just don't know what you have available to you - of course the VTL is always a solid recommendation as well.
