Local stacked ESL demo night....

[Rug Doc]

That’s clippin’.

That’s clippin’.

If so and on digital maybe of the 44 if it was an early one. Pre-grey Quad preamps can be a tad startled by the 2V signal unless its going through the tape input, plus the way the gain staging works in the 44 & 34 (as I understand it) it gets worse as the volume control is advanced, i.e. its more complex than just clipping the input stage.

I actually bought a new 44 pre. to power my RCA mono's back in the day, having had its awful predecessor. Yes, the 44 was dull as ditchwater, as I discovered. It disappeared in a house move a few years later, so it wasn't even reliable enough to stay around !

I'm surprised, like you, that such crappy amplification could produce such a result.

Sorry, but you must have missed the and all of the ' '

Perhaps they had inserted a CD module.

I looked up that singer and listened at home, and I definitely don’t get the same sense of being at a performance, sadly. About 90% certain it’s down to room size/type, but also I felt the stacked Quads imaged better. I’m telling myself it’s due to various reflections that I don’t get in my (much more heavily damped) room. Or maybe I just still hold a candle for ESLs….

I have a pair of stacked quads just sitting here ,not used for 6 months

£600you can have them i need the space

 

[JTC]

Very tempted! Just doubt I’d get them past the FPO…

 

[RichardA]

This thread is a nightmare. I am v happy with my 63s but I have started measuring my room for the size of stacked 57s and I’ve never even heard a set.

You say you need the space but £600 for TWO pairs of working 57s seems insanely cheap. Are you feeling ok?!

 

[chartz]

They must have little charcoal spots all over

 

[piccadilly]

I don't have the space. But I would give £600 for TWO pairs of ESL 57's

 

[JTC]

One thing I could potentially do is borrow the stacked pair and try them chez JTC

On paper the Luxman should be more than up to the job but nothing like an actual test to be sure….

 

[ToTo Man]

Are stacked 57s supposed to be wired in series or parallel?

I assume you’d just bi-amp them, as in this case. There were two 303s, each driving two ESLs.

 

[chartz]

In series doesn’t make sense I think.

 

[Darren]

I looked up that singer....

Can you please share the singer's name and album title - I very much want to try this with my Maggies now.

JTC mentioned his Luxman so I presumed he was contemplating driving both pairs from that. I don't think this would be a good idea in conventional parallel wiring due to the 57's impedance curve. Wiring in series would present an easier/safer load to the amp but would presumably half its maximum output power. I suspect bi-amping would be the best way to go.

Are stacked 57s supposed to be wired in series or parallel?

From Quad Technical Information, No. 021:

"It is important that the ESL's are connected in parallel and we would advise that each speaker is fitted with our clamp protection circuit kit QELCLPK - see TI 001."​

Well, I went from stacked 57s to 63s and never regretted it. Still have 63s and a single pair of 57s in storage.

This thread is a nightmare. I am v happy with my 63s but I have started measuring my room for the size of stacked 57s and I’ve never even heard a set.

 

[al2002]

Back in the day Quad recommended parallel connection. I used a single 303 then a 405 with the limiters
