Apogee Scintilla Power


I know this is an old topic but here in 2019 has anyone come across any “new” ideas for driving Scintilla 1 ohm’s?  Just looking for some options. The obvious ones i know/heard of are old Krell, H2O, Lamm (big money) and some pretty wild european amps? I currently have a pair of Sunfire 300’s (with Scintilla mod) that actually sound pretty good and it is amazing what Bob Carver achieved here but looking for the next step. Thanks for any ideas. No need telling me to sell my Scintilla’s.....:). I am all in and really do like the Apogee stuff. Maybe its nostalgic or the journey. Thanks very much.

Thanks for your update to the thread about using the H2O amps and Fire preamp. No doubt this is a proven, winning combination for Scintillas (and sounds like your D-Sigs as well). I am currently using my Plinius SA250iv on my D-Sigs and it is really good. Can’t wait to try the Plinius on my Scintillas when they are done with refurbish. I still think about getting Henry to build me new S250’s but just don’t have the money. And I have money into my Motif MC10 preamp (which is a giant killer) and moving to the Fire Preamp would mean a change here. If he would build it I bet a new Henry Ho build would be even a step further with what he has learned along the way. I am really curious what the new Emotiva mono-blocks sound like. Doing some research it appears they may be able to handle the Scintilla load. Agree on the Duetta Signatures. While many will debate the older ribbons are better, etc. I can say that with new ribbons, XO work, etc., my D-Sigs are quite good. 
Not sure the BHK’s can handle the 1ohm load but have not asked PS Audio directly. Certainly that would be a great option with some hybrid magic. Would love to hear if anyone confirms a thumbs up. PS Audio also has some really great class D amps now. Never heard them but folks seem to really like them...
If you ever get a chance to audition the Classe DR3 VHC I mentioned earlier in the thread, do so (hard to find as less than 200 made). The pair I have were driving the heck out of Scintillas when I bought the amps.

Run in stereo they put out 40 watts into 8 ohms.  Run as a pair of bridged amps, the put out 500 watts into 1 ohm.
