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.

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... 
Thanks for the feedback. Yes, the Sunfires will stay in the collection for now. There is a 600 as well. I think the 300 is 1200w at 1ohm. Quite remarkable. Will check out Magnus and TNT. 

I tried a McIntosh MC7270 and it did not get close to the Sunfires. The Mc has a 1ohm connection terminal that is achieved through the autoformer. Ran fine, cool, etc. but did not have the punch of the SF.

Scintilla’s for $900 a deal for sure. But most likely would have required some work. Could have cost you 5-6K in the end, without a fancy finish. Based on what i have heard (which may be limited) worth it. Of course my Dynaco A25’s i picked up at goodwill for $35 sound pretty sweet...:).
