are "LONDON" pressings made in the UK, inferior to the Decca pressings


Are "LONDON" pressings made in the UK, inferior to the Decca label originals of the same record? Anecdotally
 I 've heard mixed responses to this. Anyone have a lot of evidence , having heard both?

@wynpalmer4, thank you so much for sharing this information. It really is most valuable to get first hand confirmation that UK pressed SXL and CS labels were created equal by someone who was actually there!

But in your experience the SXL's are still often sonically superior. I'm sure this will delight the SXL fundamentalists, even if the reasons are unclear. In your case 'new versus used' might go along way to explain this. Another possible explanation could be that with each pressing run the first part was given the SXL label, while the latter got the CS label. In that case the slightly more used stampers for the CS labels might explain a slight sonic difference in favor of the SXL's. But this is pure speculation on my part and it's probably not very likely that Decca would stop halfway a pressing run to change labels. Having been there, can you shed any light on this? 

I've never been able to detect any generic difference between UK pressed SXL and CS labels with the same lacquers and stamper codes. In some cases the SXL sounded better, in others the CS. Because all my copies are previously owned, I tend to attribute these small sonic differences to their past playing history. This will always remain 'the great unknown' in collecting used records.


First off one big difference is a lot of changers in use in US, not the case in UK. Also many times the Decca LP was put out first, so more likely to have fresher stampers. Charm has all the details on which LP came out first for most titles:

Here is a sample entry:
>0974
Pr: James Walker (m) Eng: Kenneth Wilkinson (m)
Pr: Erik Smith (s) Eng: Cyril Windebank (s)
15-16 Jan 1957 Kingsway Hall
Ruggiero Ricci (violin), London Symphony Orchestra, Pierino Gamba
BRUCH Violin Concerto No.1 in G minor Op.26
MENDELSSOHN Violin Concerto in E minor Op.64
(Jly57) LXT5334 = (Aug58) SXL2006;
(Sep57) LL1684 = (Sep58) CS6010, (May89) 417 793.2DM.

Here we see SXL2006 in August of 1958 versus CS6010 in September; advantage to the SXL.

Works like a charm for collecting Decca/London!

I'd lean towards SXLs because the LP was more likely played by a good turntable and needle. In the US YMMV with lots of people having nasty changers and needles plus poor LP hygiene habits. Very pleased with British dealers and the quality of their LPs.
I have thousands of records many London i have always found the Decca to have better sound even though they were pressed in the same plant.Go figure.
i have both Deccas and Londons and for the most part, they seem to sound about the same.
