Confused About Relative Sonic Impact of DAC VS. Transport


I've borrowed a Heed DT Transport to use in place of my Jollida JD100 CDP and am confused by what I'm hearing. 
My DAC is R2R ladder/non-oversampling Aqua La Voce. With Jolida in system, the sound is on the warm side of neutral without verging into tube-like, euphonics. With the Heed transport, all I seem to notice are the liabilities of every CD I play. 

If the Heed is more efficient at reading data from the CD than the Jolida, does this mean I am hearing the effect of the DAC more clearly, or am I hearing the effect of more information from the disc?

At first, I enjoyed the increased resolution, but with further listening, the sound, overall, strikes me as "thin" (as though lacking lower mids) and the highs verge on fatiguing. 

Switching out footers has some effect, as does tweaking my Schitt Loki EQ, but I'm still not very happy.

Excuse my French, but WTF is going on, here ?

BTW, John Darko, when reviewing the Aqua, recommended it as a particularly good choice for harsh-sounding CDs.

itzhak-- I have one more coax to try next week, then I will order the sim transport. I've wanted to try the 260T for quite some time but until yesterday, was unable to locate a dealer willing to offer a return policy on it. BTW; how long was the "long" break-in ? ? ? 

lowrider57-- No dedicated lines. I have two outlets and an audiophile power strip at my disposal. To be honest, I never paid attention to what was plugged in, where. It could very well be that analogue and digital are "currently" mixed up. Components are sitting on a fairly massive, built-in book shelf unit, not a rack, which means I have certain limitations regarding cable arrangement but I will definitely see what I can do about this. 

In terms of footers, I've tried old-style Stillpoints, Cardas blocks, EdenSound brass and nothing under the Heed and none of these have yielded consistent improvement, as CD SQ with the Heed is all over the place. I haven't tried mass-loading. 

I'm using the same Audio Art power cord on DAC, Integrated and Transport. I can ask my dealer friend what I might be able to borrow. 
Good power cables are not exactly cheap and as the Heed is the only transport I've tried, so far, I'm reluctant to invest a lot of money into the system to accommodate it, without trying another transport first. 
Have you tried a good optical cable instead of the coax cables you've been using with the Heed transport? I'm currently using a Sony CD player as a transport, but it does not have a SPDIF output so I'm using a Lifatec glass Toslink. The sound is very good and not harsh at all. Just another possible option to help narrow down the cause of the fatiguing sound you're experiencing.
The Simaudio 260T needs about 200 hours break in period but my impression is that you'll hear immediately that it's better than the Heed.
SPDIF cable is inferior to coax I don't recommend to change it but quality coax and rca cables are a must to allow your system to perform at its best.
