Since you are obviously a vinyl lover, can you explain why on most of my
large collection of LPs there is a very noticeable change in audio quality
between the start and end of the LP?

Philips? Not exactly renown for top end audio equipment. Apart from the
co-development of the CD far more interested in the mass market than
quality.

Sure, you've obviously got *no idea* how to set up a
turntable/tonearm/cartridge.....

Dave, have you already forgotten DCC?

Define loudness as you mean it.


OK, as I mean it: All my sources are routed through an SS control amp
which has two 'pre outs' - one goes to a valve power amp with a volume
control on my Lowthers, the other goes to an SS power amp (no volume
control on the inputs I'm using) on multiway TLs. To match any given
'sound level' at the same distance (loudness) I have to *turn down* the
volume control on the valve amp - say about a third of the way from full
volume. IOW, with both power amps at max volume (no attenuation),
switching from the SS to the valves (even only 9 Watts' worth) results
in a tremendous increase in loudness from the valves/horns.

Does that do it for you??

What is far more revealing is to compare the analogue master to the LP
produced from it. No argument there - they sound totally different...

I was probably setting up quality arms and cartridges in the days you
bopped to your Dansette. And if you've not noticed an LP quality
deteriorating as it nears the end it says much about your ears and or
equipment.

Hardly - since I've got one somewhere. But Philips were more about
inventing a standard to get the royalties from it than actually making the
highest quality equipment to use that standard. Compact Cassette being a
prime example - they actually tried to prevent improvements to the format.

Heh heh. It just shows your complete lack of understanding of basic
electronics.

Bet you look at car speedos too to see which is the fastest...
