If I wanted to spend $5k on a new turntable, just the table without tonearm and cartridge, I would be in trouble, I guess, because I wouldn't really know what to get. It would be very easy for me to choose if I could compare them all, not always necessarily side by side, though preferable. In any good system the source is heard quite clearly, it sets the pace and tone. Besides, I know well how tape sounds, I have this reference in my head.
I will sort of paraphrase Jefferson - there is more than one way to skin the cat.
