nuforce 9.02se/belles ref./ moscode 401hr?

nuforce 9.02se/belles ref/moscode 401hr/McIntosh 402 or 602/parasound jc-1's (concerned about the heat) as amp for my piega c-8ltd ribbon hybrid speakers. Other recommendations welcome. My budget is up to 5k used or new but prefer used and less than my upper range. My goal is to extract as much performance from the piega's as possible at this price point (top to bottom). My musical tastes are ecletic but I listen to acoustic (bluegrass and folk) nearly half the time. My room is medium sized and dedicated. Current amp is an aloia 15.01 and it sounds very, very good but I feel like there is much room for improvement. Amp has a low level hum that I can hear during quiet passages. Preamp is lector zoe with premium genelex tubes. Source is aloia cdp as transport partnered with the scott-nixon tube dac. I have used odyssey extreme monoblocs and liked them also but not as much as the aloia. In what way? I don't have the audio vocabulary to say but it just sounds better to me. All suggestions are appreciated and don't hold back. Thanks in advance.
