Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

Henry,
I would be more inclined to measure the in room response of your speakers and see what you get.

John,

It is very rare to find a Scintillas owner.  Are you located in Texas?

Kenny,

Unfortunately, I am not very well equipped with instruments to perform such tasks.

Erik,

Just to add a bit about the Scintillas. Sure, they are closer to a short over the entire audio frequency spectrum than any other speakers to date. It is not that hard to design a conventional linear class A amp to deal with that which I have done. But what compounding to the low impedance problem is their efficiency, and if I remember correctly, Stereophile’s measurement came up with was in the mid 70 dB or so. And Here is where it is an equally challenging task to deliver substantial power into such low impedance and inefficient load.

Former owner I'm afraid.  Parted with them many years ago - the original owner wanted them back.  Today I have a system based on the BG72 ribbon and 6 Carver hex cone woofers, and I just finished restoring a set of Carver Amazing Platinums with NOS ribbons and new woofers.

P.S.  Yes, I'm in Texas, the DFW area.
