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.

How about Jim Strickland's big TNT amp that he designed to drive his paralleled Acoustat electrostats? 250 watts @8ohms and double that as the impedance drops! I have one in my collection. Now I wish I had bought that pair of second-hand Scintilla's offered to me years ago!
Keep the mono-ed Sunfires! Those are great amps, for sure! Anything else will only be a marginal advance, if that! Honestly! And if I remember correctly, didn't Bob Carver make a Sunfire 600 Signature? Today's "boutique" amps are way overpriced and built to attract the gullible and neurotic!
If you don't want to go money-crazy with brands like Block, look into Magnus. They have some really powerful and well built amps that have been well reviewed. Then there's Mac of course, but I realize that is a polarizing subject...
