Considering Rogue Audio or P.S. Audio


Currently have Rogue Audio Cronus Magnum Integrated and want separates.  I'm running them into Spatial Audio M3 Turbo S speakers at 4 ohms.  Considering the Rogue Stereo 100 and RP5 or RP7.  Also looking at P.S. Audio BHK Signature pre- and BHK amp.  I am aware the BHKs are more expensive but would like feedback on this comparison and if you have any other ideas (no shortage here I'm sure).

I had a constant low-level hum both mechanically (transformers) and through the loudspeakers from my Cronus Magnum II.  I tried everything under the sun to reduce this--I documented some of my experiments a double of years ago on this forum.  Nothing worked, no different wiring, power conditioners, earthing, etc. etc. etc.  I really like the sound of the CMII, but I ended up listening for the hum during the really quiet passages.  So it had to go.

OP: I'd look at Backert and Raven, or perhaps tube preamp + SS power.

I have heard the RP-5 and Stereo 100 at dealers and shows and it is right up there with the best sounding systems I have ever heard regardless of price.
Hum must be related to the user’s home wiring. I have never had any issues.
I just took delivery of a Rogue RH-5 headphone amp linestage. I am not into headphones and I bought the RH-5 because it has balanced output. My new solid state power amp has balanced connections and the difference between balanced and regular RCA connections is well worth the capability- more dynamic, vibrant, resolving and clean sounding. Worth your consideration.
