Default Apogee Scintilla amp

Which Pass design can drive the 1 ohm Apogee Scintilla ribbon speaker? If I bi-amp and play at sound sound levels...

Tough load. Wants lots of power.

X600 is the best bet.

No Pass DIY design, then.

I used to have a pair of Scintillas before buying Divas.
With Scintillas one has to keep in mind not only the 1 Ohm
load but the low efficiency as well.
Anyway I tried Rowloand Model 7s and they didn't last more than an hour before their thermal protection circuit turned them off.
I tried one pair of ML No 23s (passive biamping) and the same thing happenned.
In both cases the looseness of low bass caused me a terrible headache.
The only amplifiers I found capable of driving the Scintillas to their limits and at the same time delivering a tight low end were the Musical Fidelity 570 monos.
But I didn't like the sound of them.
So I sold the Scintillas and bought a pair of Divas.
Now, Passlabs make some of the finest solid state amplifiers
available.
But I really don't know even if the X1000 would be able to control that woofer.
And it certainly is to expensive just to give it a try.

Why don't you get rid of the Scintillas and buy yourself a
pair of "normal" loudspeakers?


Good luck,
Nick

It's not actually that difficult to build an amp that will drive
the Scintillas; you just have to get medieval about it.

Thumbs up Scintilla plus Pass X-600

As a fellow Apogee user (Thomas, you know me, don't you?) I can say with full confidence, the Scintilla is the cat's meow of all speakers, including the Diva. What's more, as the one and lonely says, the X-600 does it well. I say, the two are a match made in heaven. I can top a hundred Hz (though I most rarely do) without a whimper from the Pass. Almost all of my listening is done within the 600's idling current, class A, where the Scintilla cruises in the 80 Hz range. Bass? It ain't no Krell, and thank the pinnacle for that!

Say, I know a guy who powers his Scintilla, Diva, Duetta, Caliper, (almost always Scintilla) with a DIY 85 watter and absolutely loves it. How's that?

This is what a friend of mine wrote to someone with an inquisitive mind:


Hearing the Scinnies would not be any problem. My friend is home during the day and LOVES to show off his Scinnies.

WARNING: LISTENING TO SCINTILLAS MAY LEAVE YOU FEELING INADEQUATE!!!!!! You will be required to sign a
"release from liability" form before you can listen. You must also bring a signed permission slip from wife or SO.

What happened to Apogee, the company? I have always wanted to own one of their speakers. Are their speakers problematic? I know they are hard to drive.
