I like their sound. Wish I had a place for them.

Well, I ended up with a silver Yamaha R-N600A. It nicely compliments the Heresy IVs and does lots of streaming and looks *almost* 1975, once more! Sick of black.

Hand made.

Yes. Among others, Crites Speakers sells a diaphragm mounted on its carrier for an easy no solder replacement. Klipsch may carry replacement diaphragms as well. Some say some of the diaphragms on ebay are substandard, so watch what you buy.

There's your sign! Made by Eminence.

Look up her performance with Jeff Beck!

Most likely. Look on the back of the cone for an ink stamped part number for the cone. Then, look for the EIA date code, usually 6 digits, like 67-YYWW, on the magnet, to verify it was made by Eminence (67). Then call them and ask.

You want to use high quality film and foil capacitors. Metalized film capacitors can sound harsh/gritty with that tweeter. A darker or recessed/distant sound is a common description of caps that are old and have gone off-spec somehow (probably ESR).

The short horns in a Forte are unlikely to benefit at all. But, ..... I can't see how it could hurt anything but your wallet. Longer, larger horns of other materials do show some reduction in edginess.

Sorry Duke, you left out the "L".

I got a quote from Audio Classics to make for boxes to ship the McIntosh gear. They want $150 (shipped to CHI) for a box for the MR74, MI3 & C26. They want $175 for the 2505. The buyer will pay for further shipping, but at least you can have a high expectation they will arrive undamaged. I looked them up and the prices Gil is asking are very nice. See page 6.

Anybody going from Chicago to Denver and able to transport a pair of Quartets?

Put here for Visibility. Anybody want to loan/rent/sell Quartet boxes? Gil McDermott has a pair of Quartets he may need to ship to sell. If they survive, we'll ship them back to you.

I'm sure they could, but I wouldn't recommend it. My H IVs were safely shipped in their original boxes, on a pallet and wrapped with film. We don't have the original boxes and Miss Amy does not have the capability of taking them to a trucking company to be packed and shipped. If you are serious, we can try to make that happen. It will not be cheap. I can try to have boxes made and we might use UShip. My experience with them has been good for 2 shipments. Anybody want to loan/rent Quartet boxes?

We strongly recommend personally picking up the McIntosh gear as the glass faces are somewhat fragile and difficult or impossible to replace/repair. Audio classics.com has or makes shipping boxes for McIntosh gear and we recommend getting a special box for shipping these. I have asked them for a quote on the price for each box. See pics on page 1.

Got mine today, too!!!!

That sounds like a protection circuit activating. That amp has more than enough power at 150 watts/ch. It's hard to diagnose from a post, but I'll bet the tweeter protection is saving your tweeters. Turn down the volume. All things have a physical limit. You've found one.

Feed the Sixes with the preamp outs on your A11 or trade it for a preamp only. Keeping the A11 has more flexibility.

None of that sounds off at all. The PrimaLuna should be excellent and it has plenty of power. It sounds like you may have 2 issues. The woofers are new. Woofers really do need some time to loosen up. After I first heard them, I was disappointed in my new Heresy IVs thin sound. So, I ran dub-step with full bass boost through them for about 80 hours (not too loud). Just shut the door. At 40 hours they were much better and probably didn't change after that. Give that a try. You can experiment with using the 4 ohm speaker outputs, too. Older La Scalas ran about 6 ohms in the woofer's range and I expect the new ones do, too. The other is that the La Scala's don't reproduce the lower 5 or 6 bass notes of a double bass/bass guitar very well. Cornwall's will, but also add some distortion that will "fatten" the sound.

How about a nice pair of Belle Klipsch? In Chicago? Or even 3 for a center-fill?

Heresy driver magnets are not that kind of magnet. Sounds like an ignorant decision made without data.

Magnet too strong?! For what? Who, that was qualified, made that statement? How absurd. Probably you should look at FedEx or DHL and just ship them back to Oz.

I'm working on that. There are some pics in a PDF on page 1 of this thread. I just talked to Gil. He said he'd be glad to go with someone to the location where everything is stored and talk "turkey". You'll need to come with a truck or van for the larger stuff and pick him up where he lives. We will pack and ship the smaller stuff, at buyers expense. Contact him at w.f.mcdermott@gmail.com or PM me and I'll give you his phone number.

No speculation whatsoever!
