Class D is just Dandy!

There is no way an Apogee Scintilla will sound anywhere near it's best driven by ANY class-d, and they could just switch off or blow up.
 
Not only is it 1ohm @100hz, but it has a massive -90 degree phase shift at 100hz also, these two together mean almost a dead short as see by the amp.
Only the biggest heaviest Refererence Monoblock Krells of yesteryear can drive those sort of loads and sound good.

To quote a great Australian movie (The Castle)
"Tell'im he's dreaming son."

George,
If I'm not mistaken,do you still have a pair of ref600m.
If so what amps do you like better and what speakers do you use.
Just curious.

George,
If I’m not mistaken,do you still have a pair of BC ref600m.

No don’t own them, but of all the D’s I have heard they were the best, "BUT" only when they drove an expensive Raven ribbon tweeter’ed two way bookshelf. This Raven has a very benign flat 4-6 ohm load and not much -phase angle to contend with, the whole speaker was an easy drive.

If so what amps do you like better and what speakers do you use.

A pair of these ME1500’s the one for the esl panels in 100w class-A mode the other for the bass in 25w Class-A mode.
And highly modified bass Martin Logan Monolith III with the newer aluminium vapour deposited Neolith esl panels.

I also loved the sound of these on a pair of Quad ESL57's, but you've only got 25watts.

Where do you get your data on the Scintillas?  I owned a pair and measured the impedance magnitude and phase (scroll to the bottom):

No 90 deg phase shift at 100 Hz.  A very well behaved 1 ohm in that region.

George,
I bet that combo sounds spectacular.

If I owned Martin logans either past or present,I don't think I would use a class d Amp of any kind,just my opinion.

I personally have gone a different direction,usually a person buys the speakers that they like and then pairs the right amp for them.I like my class d amps so much that I'm gonna find and pair the right speakers for them.Kinda unusual but that's me.
