Replaced CDP w/ Transport; Now, Soundstage Changes Dramatically w/each CD. Why?

What I think Geoff was referring to is that with 3 or 4 points the existing cdp sits upon you would ONLY need to shim 1 or 2 to change level.

Would be crazy to shim ALL existing points although you certainly COULD!

Actually my point was, for a component with a foot on all four corners, if you remove one foot the component could easily topple over. You can get away with three cones only if you can arrange them in an equilateral or isosceles triangle. Three points may define a plane but four points are usually more stable.

geofkait: you left out tiddlywinks. . . and whether genuine tortoise shell,  ebony or titanium 'winks yield superior sonic benefits ! 

I've had the Heed DT in my system for a couple days, now, and am really liking it a lot. Although the resolution is, in some cases, dramatically improved over the Jolida CDP, I've encountered no listening fatigue or etched highs. I'm assuming this is due to a particularly fortuitous match with the Aqua La Voce DAC.

PRaT, a factor crucial to my listening enjoyment, is simply amazing.
Overall, I definitely have a sense of entering more deeply into the music. Instruments have more dimension, timbres are more colorful and vocals more palpably real. 

I'm looking into the possibility of purchasing a back-up drive for the Heed. Is there some sort of database that lists which drives are in which units ? 

You should be a reviewer. 😬

The bad news / Your Heed is not on it
