High end stereo preamps? Worth it?

Not going to dig out the references, but I used the Lamms as an example bc reviewers in Absolute Sound, Stereophile, and several other journals have said it—repeatedly—about every iteration of the Lamm SET products. I chose the Lamm example bc they have relatively high THD graphs and pros said they sound better than pretty much everything else out there. 

Benchmark LA4  Line stage device sounds interesting to simplify whatever a stereo preamp does.   For streaming only, seems ideal and wonder about amp matching issues.
Wish it came with a ht bypass.

Not going to dig out the references

Yes they have their following, but not among "vast majority of professional reviewers".

Ok

@sokogear-@itsjustme - no - I was talking about going straight from a phono stage to a power amp.

Not clear what you are saying "no" to.  Precisely what i was talking about.  RIAA --> Power amp is "no preamp".

No matter just a bit confused.
