Thanks, I'm so glad the whole thing is finally over. It took right at two weeks for the whole project(a lot of that was waiting on parts to arrive). But this job was really a pickle. Just to give you one example....the eht board in the power supply! The board is in-cased in  bees wax, so that involved slowly bringing  the heat in to oven to 300 and baking it for around 20-30 minutes. It was a very fine line between all of the wax not melting and the board and housing itself melting. Then the diodes that were on it had very thin leads with very thin holes to mount them through. So I had to carefully drill out 16 holes per board(would have been 32 if they weren't laddered) while not damaging or lifting the solder pads.

 

And it became more difficult from there with most of the soldered parts being a combination of  wire-wrap and solder. So just unsoldering a part took a lot of time, and patience. If one would become impatient and to to force a lead loose, solder would splatter with a good chance of it getting into the panels which would mean  replacement or a complete rebuild from scratch. So on the technical side, it wasn't too bad. It's just very time consuming.

 

But it was all worth it!!. I know these quads have many fans, and  many claim these to be the best speaker ever made. Well...I completely disagree with that. No way could I ever make that claim about a speaker with two serious flaws. The first one is bass. These sound like there's a  low pass crossover at around 70hz. The bass is very defined and perfectly intergrated but there's both a serious roll off and and attenuation down low. The second flaw is the beamy treble panel. On axis, the imagine is pinpoint and precise. But off axis, it's like there's not much treble at all. Many try to compensate for this by adding ribbons, but fortunately for me, it's a non issue since there will only be one chair sitting dead center in my listing room. 

 

But I will say, for the frequencies they do produce, they are just superb. The mids are if not the best, at least among the best I've listened to. I do wish they had the dynamics, depth, and sound stage width of my acoustats, but they are still very good in that department. Now the research and modeling begins on a good matching sub. I'm probably going to end up going diy with that project. But tonal wise, I will say I haven't heard none better.

Great impressions Moody. Tonality is very important to me so I'd probably like them. To be fair I'd probably love them! The depth will most probably improve when you get a sub.

That's the most important thing to me as well. The others aspects I consider a nice bonus, but I will take a speaker or headphone with great tonality over one that only excell when it comes to other aspects. That's one reason why I like the w3000anv over the hd800, but that's a discussion for another forum lol. But the quads and my 500c are a great match, and I'm very fortunate to already have an amp for them. These things are known as amp killers.

Quad ESL 57 is the only loudspeaker to challenge and actually match/beat the Beveridge in the midrange - and yes, it falls short in the areas you described so well. I would try to match it with NON BOX subwoofer - dipole of some sort.  Depending on size of your room ( and piggybank... ) that can range from some small DIY job up to Carver Amazing Loudspeaker - used as subwoofer only...

 

Gradient of Norway Finland ( used to ? ) produce dipole SWs intended specifcally for the Quad 63 - doubling as a stand to elevate the ESL panels to eye height when listening seated. Unfortunately, never heard a Gradient assisted ESL 63 - but those who did have high praise for the combo.

There is a succesor to the original SW57 ( made to complement the ESL 57 - discontinued) :

Thanks, that's great info. I'm very well aware of the amazings and they were on my short list before grabbing the quads just on my intrigue of the open air woofers. Ultimately that would be the way to go, but these are going in my small office, so that may be overkill unless I can find a small but elegant design. But I'm glad you reminded me of the concept and my first goal is to try to make that happen on a smaller scale.

 

The fisher is really showing what it can do with the quads though. I really love this combo. I really can't wait until I get the sub thing solved like I did with the acoustats.

No problem - I just wanted to remind anybody about the most important property of any loudspeaker - interface with the room.

Some more DIM ( Drooling Inducing Material ):

For a small office, I would just dispense with the subwoofers...

 

ESL 57 is not power hungry, in fact one has to be careful not to overvoltage it with too powerful an amp when reproducing high dynamic range material. But it definitely is showing what anything preceding it in the chain is doing - meaning your Fisher IS up to snuff !

I figure here's the best place to put this out first-

I recently bought a large stock of parts from a radioshack service department that shut down a few years ago. One of the boxes had about 450 vintage N.O.S. IC's. Many of the year dates are from the mid 70's to mid 80's. I know there are people out there that need unobtanium parts, so if you need something, send me a PM and I'll give you my inventory list.

THAT is a very generous offer. No idea what RS could have been stocking in those days, I will shoot just the general question : anything from Matsu****a/Technics ?

A very few. I have them sorted by part number and didn't catalog the manufacturer, but I remember seeing a few of their manufacturer codes.

post #12238 of 13302
If you happen to have any, STV-3H, 4H, etc bias diodes are hard to find NOS. They are easy to damage if you screw it in too tight or pull on the brittle leads while recapping/servicing.
A stash of these would be great to have.

I'm finally getting my Pioneer CTF-1000 cassette deck operating.  Bought it with the Spec rack system and tho the lights came on the wheels would never move. 

 

My question for you guys - would you keep it to preserve the "silver face" legacy and keep the rack mount system "full" of Pioneer stuff or would you sell it after it's working properly for from what I see on eBay and from a prior conversation with Skylab for upwards of $1000 and invest that $$ in another killer system. 

 

Have a 1280 and 1050 locally for sale for $800-900 so in effect I could trade the cassette deck for an amazing receiver. 

 

I will likely never use the cassette deck so the value is keeping the rack looking "period correct".  I could see both points easily.  Have no intention of selling the system and in fact will pass it on to my daughters some time down the road (20+ years?). 

 

I'm wondering what would YOU do?   Thanks for your input. 

post #12240 of 13302

I personally wouldn't keep a $1000 piece for cosmetics/completeness only.  There's just a lot of other cool stuff you could get for that kind of $.

 

If it's not already out of your rack, I'd take it out of your rack and see it and imagine it gone.  Would it bother you?  If not, I'd sell it.

 

If you're not sure and don't need the $ (or whatever gear you could get with the $), then take your time, because it may not be easy to get again.
