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.

The RP 7 will sound very good with the stock tubes (which are also the stock tubes supplied in new McIntosh hardware.  

They take quite a while to smooth out though, some say 500 to 700 hrs.

The RP 7, RP 5 do require a good matching amplifier.  With the Rogue Stereo 100 for example the sound of each is quite special, all with stock tubes. 

I found the RP 7 did not respond well to my best NOS tubes but the Stereo 100 sure did. 

Using random solid state amps all bets are off.
