Well, music is enjoyed from everyone in a different manner. When you hear something you like, it can be played via car stereo or MP3... it doesn't matter. Same with audiophile units...you find for everything raves and enthusiastic recommendations.
Next step is, when you think about technology and compare...it is normal that there are differences...brain is different too. Some have better solutions than others. Does it mean that they are automatically more successful? No. Not in the audiophile world. The reason is very simple, knowledge is replaced from marketing. It is much more easy (and cheap) to write a few lines than to develop something serious.
I wrote about the Sutherland Timeline 2 years ago, when nobody did even know to spell it correctly and wrote about the differences in speed. Most Turntables are simply mediocre.
Can you hear the difference? Yes, of course. But it depends on your knowledge, understanding and quality of System. A female singer with a guitar in the background sounds ok with 35rpm too:-)
Now, some may think, going back to old DD is the solution...well, they have a proper motor management but they are not able from construction to be named as "High End". Let's say, they work, they accelerate and that's it. You can compensate their weeks with colored cartridges but they are the way they are...
Their electronic corrects the speed permanently, "...accelerate--reduce---hold---accelerate--reduce---accelerate---ans do on and on" based on that, listening Piano with it is a pain for me. There was a demonstration about that in the Munich High End Show 2013. All visitors rated the DD negative compared to a regular running belt Turntable...but that is only one technical point, there are much more for a good reproduction.
The Timeline should be used normally from Dealers to select a product before they buy it to sell it to their customers. Same for Manufacturers btw.
But it is ignored from all. All want to sell the stuff they produce and when no one asks for "quality"...well...then we get what we deserve.
It is much easier to shoot the messenger (I know that very well from the guys who think that black color with a few motors has something in common with quality)
Ah, btw, yes, I solved "that" Problem long time ago :-)
