Rogue audio RP-7 versus PS Audio BHK preamplifier

I have an old Rogue Audio Super Magnum 99 tube preamplifier that I will be replacing in the not too far future. I really liked the sound of the magnum 99 except for the tube hiss. It’s not audible when playing music but still bothers me, particularly when the volume is low. It also constructs the soundstage, an effect that is evident when I connect the external DAC directly to the amplifier. 

from what I read both of these models should be a significant improvement over the magnum 99. I am wondering if anyone who have heard them both has any opinions/thoughts on how they compare.

Have had a BHK preamp in my system for a week now. Replaced a Rotel RC-1590.  It was a very noticeable change in sound. Only 35 hours on it so far. I am using Bob Carver VTA-180 mono blocks using all Gold Lion tubes. I have tried 4 or 5 tone tubes in the amp. Came to me with medical grade 50s era Mullard tubes. I found them too bassy and no high end detail.  Of course, I have Klipsch Cornwall III’s with a 15” woofer.

BHK preamps are shipped with Gold Lion tubes. Depending on your system, it may sound bright. Like jackd said above, the beauty of tube gear is that changing tone is just a matter of finding the right tube. I like that the fact that as I upgrade, I can adjust the sound as I go. 

Happy listening.
