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

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 good news / Here's a list:

The bad news / Your Heed is not on it

boxer12: thanks; I'm familiar with it. . . unfortunately, it doesn't include Heed. 

geoffkait; Hah !  I'm afraid I'm not very good at explaining what I'm hearing without resorting to cliches. Usually, the only times I step back and focus upon sonics are occasions like now, when I've just introduced a new component into the system and my ears have yet to fully adjust to the change. In other words, the element of novelty is still very fresh. I welcome the intellect to the listening room when the focus is gear but if the focus is music, I want to be IN the midst of it, not sitting off to the side, analyzing. 

back to cables. WireWorld knows what it takes to make outstanding cables. The higher up their product line the better the sound, but whatever they offer in your price range you can count on for excellent value
