Tvad, I agree with your comments as to what constitutes an analogue front end table, arm, cart, phono cable etc. etc. Many folks conveniently leave out items such as cabling and phono stages in their costing.
I mentioned earlier that you have to spend more an analogue than digital for analogue to start matching, never mind outperforming, digital. However, I found that the 5K mark is a threshold where a carefully assembled analogue front end will match digital and start beating it sonically. Disclaimer is that I do build my own amplifiers (pre, phono & power) and often purchase used, so the $5K number is relative.
I own two Technics TTs and like them, but I am somewhat surprised to hear that you use an SL1200 as basis for a $4500 analogue setup. Long story short, a cart will only perform as well as the arm that supports it will allows it to. An arm can only support a cart as well as the turntable which it resides on supports it. IMHO you have over-carted both your TT/arm and your phono stage.
I am not surprised you prefer your digital setup I am sure I would also. However, you may think differently if you were exposed to a more evenly constructed analogue setup.
That said, the appreciation of sound is as subjective as anything out there. Im always sorry to see somebody turning away from analogue, but whats good for the goose is not always good for the gander.
