Just one more small example of the murky nature of all this. In a recent listening session in a very evolved, very high end system not unfamiliar to some here, we changed out the support "cones" underneath the power supply for the motor controller for the turntable. How much more removed from the signal chain can you get? Well, the difference was between very good and unlistenable! So which is the sound of that component?
I can testify to the truth of Tim's statement, it was my system we were testing on.
Even more odd, it was NOT the Walker Black Gate controller and matching Walker Proscenium Black Diamond table responding violently to footer swaps under it's power supply. It was my rather ordinary Technics SP10 MK2 and it's factory supplied outboard AC/DC box.
What Tim did not hear are the interconnect cables I've compared since then, running between my SME 312S and Aesthetix Io phono stage. Each of these cables can seem as big a sonic swing as switching between the Dynavector XV1S, Air Tight PC-1 and Koetsu Jade Platinum cartridges.
I'm not saying you can make each cartridge sound like the other by just swapping cable, but rather the differences BETWEEN these cartridges are drastically altered by the tonearm cable. This to the point, that a wrong decision could easily be made about an arm, cartridge or even an equipment match.
Another variable is loading. If you terminate the Air Tight PC-1 into the typical input 47K ohm load, it's performance is very disappointing. Too much high frequencies, no bass and obvious distortion. Reset the load to 240 ohms and it's one of the two best cartridges I've ever heard.
I wish it were not so complicated, but it is. This is exactly why I am so hesitant to type in absolute answers in threads at Audiogon. There is much to consider to get remotely close to absolute. It turns out to be a continual learning process with small gains eventually adding up to big ones.
