Please recommend a $1500 SS or Hybrid integrated to pair with Silverline 17.5 monitors


I'm seeking more power in my system (Jolida 302B 50 watt tube integrated , Jolida JD100 tube cdp and Silverline 17.5 monitors) and have $1500 (used is OK) to spend on an integrated. I've got a Peachtree nova 150 on order and am wondering what other units I should consider that are tipped toward the warm side of neutral (non-fatiguing highs, better-than-lean mids). While I may, in the end, wind up staying with tubes, at this point I'm interested in exploring alternatives. I tried a 100 watt Margules ACRH-1.2 and liked it very much but it had a ground problem and I've heard from others who've had similar issues, so I'm looking for alternatives. I know Vincent makes a 50 watt hybrid but I suspect it won't rival the quickness and exciting dynamics I heard when the 100 watt Margules was in my system. I also tried a Parasound Halo but found it rather uninvolving. I guess the Rogue Sphinx might be worth a listen. Has anyone compared Sphinx and nova 150???

I've used my Anthem 225 Integrated with Silverline Minuets and it sounded nice.

Different speaker, but I've been happy with the Anthem across the board. Plenty of power, sounds great- not a lot of bells and whistles.
czarivey; I see there are currently two used 400xi's for sale for $1400. What's the difference between 400i and 400xi ?
