Has anyone compared Rogue RP-7 to Cary SLP05 and / or Audio Research Ref 5se?

I hear everyone. I don't plan to change tubes until I feel every thing is broken in.  I know from experience what a regulator tube can do.  As far as the "front end" tubes are concerned I agree I have to hear what I'm working with.  I all cases, I'm excited about rolling the SLP-05 into my system.  

Just to be fully transparent I lived in Cary, NC for 34 years and know Dennis Had. Even with that connect I believe the SLP-05 is an end game piece! 

Everyone thanks for all the great information.  I guess what really interests me is the "6" series tubes.  Sounds like a number of great options.  Now to find something I can try out.  Additional opinions, suggests, recommendations aways welcome. 

Thanks again. 

Thanks for all the great input.

Atma-Sphere makes great equipment but out of my reach cost wise but thanks.  
 

Sounds like the Cary might be my best bet.  Now to find one on the used market! 

Pull the trigger on an SLP-05.  Now what tubes do I need to roll? 

The Cary is very nice.  Breaking in some NOS tubes but very happy.  I think it is my “end game” preamp, which was my goal.  It is a great balance between detail, midrange warmth, base and sound stage.  Sound stage is actually very good.    I’ll follow up after a few hundred hours more of listening.
