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.

“Constricts” is what I meant in the previous post

Jackd, I did not think about this but you are correct. Very important consideration in my mind. Do you have any suggestions as to other tubes that would make the bhk a tadd more tuby/warm?

Thanks bigkidz. My mind is pretty set on replacing the super magnum 99 at this time. Although, I am curious about the reliability of Rogue. It worked fine for 10 years but in the past 3-5 years I had to return it 3 times for various malfunctions.

It's another factor on my mind when I consider the two replacement options - the RP-7 versus the BHK preamp from PS Audio

Thanks irrenartz. I too am interested in PS Audio’s trade in, hence inquiring about the bhk preamp. May I ask what other equipment you use in your system to get a better sense of the brightness of sound you mentioned?

Thanks Mike. My speakers are Triangle signature delta (high sensitivity) and the Bryston 4B SST is 300W into 8 Ohm, so I think I might have the same hiss you are talking about. I have a low level hiss that is not noticeable when you play music with my current Rogue magnum 99 and I certainly would like not to have it in the new preamp. Others have said that the RP-7 is dead quiet, so not sure. Maybe the tubes in the RP-1 are different? or the fact that it is balanced helps?
