Quads 57 -

No, actually 8 Ohm is the correct setting for the stack as the impedance curve is not flat. It is a compromise and it depends on the amplifier being used.

I just picked up Wayne PK rebuilt quad 57's. Have been listening for only a couple of days. The panels were sent to him to rebuild by the previous owner. They do not have the protection circuits.
I also own Acoustat Spectra 33's and Model 3's as well as other cone speakers.
I am impressed so far. I admit I am very timid about over driving them though from what I have heard. As Wayne told me - when it happens it is without warning - and once done it will happen again more easily.
The highs sound fine to me and I am getting 40 HZ - they are 5 feet from the front wall and about 7 feet from me.

A few years back I had two pairs of Quad 57, stacked the way Peter Walker said to do it.

I used an AtmaSphere S30 and the Atma Sphere MP3 and my friends told me that the sound "draws you into the music".

I really enjoyed the set up, and one of my better attempts at the "last great system".

But you know, after awhile you start to focus on what you feel are the systems shortfalls(lack of top and botton freq)so you start to bulid another system to address those issues, but you find that few if any set ups ever have the mid range magic of the stacked 57's.

I would suggest you buy the 57's, they've been rebuilt and should last you for a long time, and if you start to focus on the lack of highs and lows, don't sell them, just find a substitute pair of speakers and listen to them for awhile and then go back to the Quads and you'll appreciate them even more.

Lacee - when I brought them home they were bought already.

I have multiple speakers in two locations.

I already look forward to listening to them every week and enjoying their sound.

Even my teenage son picks up on how special they are. I have them in a room with Acoustat Spectra 33's and switch between the two.

On the advice of an audio friend who has multiple 57 pairs I put a 6" piece of 2 x 4 wood under the rear leg and wow -The image rose about 3 feet and the soundstage improved dramatically.

It's not hard to make nice DIY wooden stands for the Quads and they do sound better off the floor.

Just take the side trim off and use long screws to the DIY wooden stands.

You place the speaker between the stands, it's a two man job to set them up.

The stands are simple "T T" stands, the "T T" is upside down in this case.
