Raven Osprey vs Octave 110 with low sensitivity speakers


I’m wondering if anyone out there has experience running the Raven Osprey into low sensitivity speakers. I have a pair of Boenicke W5’s that are some of the most amazingly life-like speakers I auditioned in the hunt, and with breathtaking soundstage—in an amazingly small solid wood cabinet. The price you pay is that these 4 ohm speakers are extremely hard to drive: 83-86 dB sensitivity—and I have them in quite a large, open room. Right now they are driven by a Parasound Halo integrated which does a fantastic job in powering them, but I’m in search of even more resolution and detail, and also did want to give tubes a try. My choices are used Octave V 110 SE vs Raven Osprey. The Octave definitely has the power, but I’m told might not be quite as resolving in the upper registers. The Raven Osprey is a lower power unit, but does have the subwoofer bypass that allows me to take some of the load off of the amp (a digression on Boenicke customer service: Sven Boenicke was kind enough to personally go through my room characteristics and set-up to advise on speaker placement and sub integration—although he seemed a bit sad that I’d risk corrupting his sublime bass characteristics with an outboard!). The Octave is a known, the Raven would be unknown since I can’t audition and would have to deal with the hassle of returning/restock: is it just asking too much of the Osprey to power these little beasts? Is the Octave a no-brainer?

@twoleftears,@twoleftears,
I just did, Mr. Miller has a Melody tube integrated. Apparently he has no direct, first hand experience with Raven equipment. That is odd!
Then how come he goes around highly recommending these integrateds?
I mean no disrespect to MC. It is just plain weird!

thanks for your suggestion. I listen mainly to symphonic music and jazz. I believe 30 watts would be better. I tried a 12w/c integrated and was not enough power/headroom. My room is 11x20 ft.
