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.

Once you reach a certain level of transparency in the system, all of the cables become very important. It seems to me there is always a bit of trade off between getting a high level of detail, yet retaining warmth and liquidity so many of us enjoy.

In general, and I mean very general, I have found the following to be true. Power cords can be very important, particularly the cord to the DAC. Try to avoid nickel plated connectors anywhere in the signal path. Silver, silver plated, and rhodium cables/connectors can add detail and air, but can “thin out” the sound, and lose some warmth (mids and bass). Copper and gold can be your friends. Gold plated connectors will add warmth. A power cord with a connector like an Oyaide P-079 might suit the DAC.

I have not listened to a Blue Jeans digital cable, so I can’t comment on it. But, I listened to a number of digital cables and they all sounded different. I ended up with not so cheap Jorma digital cable as it was the first cable in my system that rendered high details, was not grainy, and had some warmth.

Audio Bacon has a nice writeup on some digital cables. The article includes the Audio Art cable you mentioned previously (looks very similar to the DH labs cable I suggested with better connectors).

With the newer Heed transport it’s more than likely you won’t need to use the reclocker. The reclocker can’t necessarily fix the sonic characteristics of various cables. Different digital cables will sound different, and not just due to jitter. Also some CDs just sound better then others. Depends on the recording and mastering.

The Cardas digital cable may help. Cardas has a reputation for having warmer sounding cables.

Well, you have a lot of silver and silver plated cabling in the system which can tend to highlight the upper end.  The Belden is supposed to be "musical" and "tonally rich".  I have not tried it, but many have.  I think you may need some more copper in the system.  Gold, too. 

 Look at your power cord and see if it's a rhodium (silver) or gold connector(s).  Rhodium can tend to sound a bit hard and thin out the mids - at least in my experience.
You might try a Belden 8402 interconnect.  They can be picked up pretty cheaply on e-bay.
