Which basic amps can drive 1 ohm loads ?


Which amps will drive 1 ohm loads like Apogee Speakers?

Scintillas? Seadogsl, how much money do you want to spend? Old krells would be your cheapest way out, but if you want to get the best out the best speaker in the world (IMO), then the Pass Labs X600 monos are unrivaled (IMO). Old Krells probably will have maintenace problems. Pass X600 amps are still relatively new, and are fine used. Expect to pay approximately $7000 for used ones (still a lot cheaper than Gryphon.)

See me and the boys + one girl at:

No they won't. There is no reason why they should have to.
There is only one 1 ohm speaker in existance, and precious few of those. No amp builder is making amps for the Scintilla. The Aragon just doesn't have the heat sinks to do the job.
I have no quarrel with chunky class A amps with huge heat sinks being able to run a 1 ohm load. Classe amps of that descriptin do power the Scintilla well. But that does not mean they have the best synergy with the Scintilla. It may have been true a dozen years ago. If the Pass X600 wasn't around, I would have thought seriously about the Classe..
Wow, Sean, I have been an Apogee nut for nearly twenty years, and I have never heard of Apogee mods... home remedy tweaks, yes.

My last speakers were Sigs. Awesome.
Kool, nobody runs Aragons on Scintillas. Duettas, Divas, Calipers, yes, but not Scintillas. Scintillas run on an average 1 ohm, and dips down to .6 ohm. This pulls a tremendous amount of current through the amps, causing huge temp rises. This requires giant heat sinks or fans, neither of which the Aragon has.
Thank you Ghostrider45

Notice Seadog hasn't been back to tell us just what 1 ohm speaker he is referring to?
So, Seadog, how did you come by Scintillas, and what shape are they in?

There is a lot of help available.

I am powering mine with the X600. These are 150 pound monos that idle at 600 watts.
Sogood, thanks for the compliment. You succinctly wrapped up the amp options.

Good luck Seadog. West coast, or East coast?
Ritteri, I am not arguing about whether the Palladium has the current to run <1 ohm. I just would not put my money on them surviving high dynamic peak fluctuations.

There are very few <1 ohm speakers out there. I own one of them. My X600 monos have enormous power capabilities, and huge heat sinks. Even they get too hot to touch more than momentarily.

I know a lot of the <1ohm speaker owners. None use Aragons. Many use Aragons on 4 ohm speakers, mostly in a bi amp configuration, the Aragon being relegated to bass panel duty.

Rit, why are you so adamant? Are you a dealer? Seadog is doing this as a favor for a friend. I dare say he has already made his recommendation.

I own Scintillas. I know others across the world that own Scintillas. My word is backed up by real world experience.
Sean, that was a relief. I knew I was familiar with your name. The JC-1 is a great amp, so I heard.

Having the X600, I don't have to do math (luckily). I just follow the needle.

At <1 ohm, I need to go to live levels to swing the needle into AB. AND at that point, if it weren't for the needle, I wouldn't have ever noticed.

There is a fellow in our Apogee group who has the most advance listening rooms I have seen. There are Apogee Full Ranges forward, Apogee Duetta Signatures righ and left, with Divas in the rear.

This fellow employs a lot of Aragon's as great workhorses. They do the Duetta Signatures, and are on the bass panels for the Divas, and Full Ranges.

He also says Aragons are great amps for starting points. All these are 4 ohm speakers.

For Scintilla, one fellow tried an Aragon 4004 MK11 that overheated.
Ritteri, I own Scintillas, like I have said before. I bought the X600 as an assurance I could not only power the Scintilla, but as well squeeze out the last drop of ecstacy these speakers are capable of.

The Pass X600 has twice the size torroidal as the Palladium, more output devices, Hexfets, and more power storage capacitance too.

Mine is definitely bigger :)

Despite these great amp's muscle, they offer just what the Scinnies need and nothing more. I know there have been others getting by on Classe, Aragon, and Krell amps, but I am interested in ultimate performance, not can do.
I've moved on away and above all of the above amps. I am now powering my Scintilla with the Acoustic Reality eAR 2 MKII amp. This is a diminutive digital powered by the ICE module.
Actually, they are Apogee Divas. They flanked Mozart's piano, giving voice to recordings made on that piano. It is just that the Scintilla gave all Apogees a bad name as amp eaters. This is not so.
If it were true Apogees are expensine, difficult to drive, and require heat-producing amps...etc. I could see your point. ;-)
