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

Hi testrun,

I owned the RP-7 and currently own the SLP-05.  

I usually love rogue audio products having owned the cronus magnum ii, RH-5 linestage / headphone amp and stereo 100 power amp.  

unfortunately the RP-7 was a disappointment from the start.  i was good but not great and I actually liked the sound of the RH-5 linestage better, momre neutral and dynamic.  

the RP-7 sounded less dynamic and more rolled off and no matter what I did I could not get the sound to open up to where it was worth the investment icluding trying all sorts of the best NOS tube swaps that i had on hand. 

the SLP-05 was instantly a big, bold dynamic sounding unit and improved even more with a NOS rectifier and some NOS sylvania 6SN7 tubes. Smooth ad transparent the SLP-05 is a big winner and I love the sound.  

Never heard the audio research.  

I had an RP-9 and it has no bloom - more SS like in its presentation. ARC Ref 6 has just a *little* bloom, is technically amazing; nicely positioned between tubes and SS, sonically. VAC preamps have bloom, a romantic sound, and gorgeous mids with increasing levels of articulation and soundstage as you move up (just watch gear pairings so the bass doesn't get a bit tubby). I’d expect any good preamp designed around 6SN7 to have great tone and good airiness. 6H30, 6922, and 6SN7 are all great preamp tubes. 12AU7 not so much.

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.

As I stated I'd lean more toward the Cary SLP-05. Since you are entertaining other options I suggest to also consider the Atma-Sphere preamplifiers (Do you have a particular budget range?).The MP-1 is superb in my opinion. this or the SLP-05 over the ARC.
