Confused About Relative Sonic Impact of DAC VS. Transport

itzhak1969-- per your advice, I was able to re-arrange cables. 

Now the integrated has its own own audiophile outlet to itself

The other outlet is supplying the DAC and the Cullen Power Box.

I've got the Transport and the 2 wall warts (for the Synchro-mesh re-clocker and Schitt Loki EQ) plugged into the Cullen. 

My first impression, having listened to several good-sounding CDs I habitually  use for evaluation purposes, is that the SQ is now smoother than it was before the cable re-arrangement. In fact, the sound of these CDs is now very close to what it was with the Jolida.  

I will have to do more listening to verify this impression, but it seems promising. ;o)

. . . or was it lowrider57 who first suggested separating digital and analogue cables? I'm starting to lose track of who's said what. Whomever it was, I appreciate the suggestion. 

mooglie: in response to your suggestion that I might need "more copper in the system" I've ordered a set of Audio Art Statement IC's.

Although some CDs responded well to running analogue and digital cables to separate outlets, I'm still hearing fatiguing highs with other CDs that were not evident with the Jolida. 

Perhaps swapping out the silver Audioquest IC's will address this.   

@stuartk , yes, there is a benefit to isolating digital from analogue. Well done.

You probably know that wall-warts are an inferior power supply. They introduce noise into the signal path and have a greater chance of contaminating the power line and other components.
I asked about how you were powering the Synchromesh for two reasons. The first is due to the noise factor of the wall-wart. The main reason is performance. A linear PS will provide clean regulated power, thus improving performance. It may also improve the leanness coming from the transport. 
 Every time I have upgraded a wall-wart to an LPS, the result was increased SQ; eg, better dynamics, imaging, soundstaging. When you’re ready to upgrade, may I suggest a Swagman Labs LPS as a high quality affordable PS. I’m using an upgraded unit on my reclocker.

Changing to copper conductors in your cables is worth trying.
You’re making progress trying to improve the sound of your digital, but after all is said and done, your best move may be to try a different transport. For the CD format which is supposed to be dying, there are many new transports coming to market.

Good morning, lowrider57:

Thanks for recommending Swagman. Their units are certainly more affordable than others I've looked at. Still, I'll have to see how things shake out. I hadn't anticipated having to buy new IC's and my budget for audio is relatively modest. 

I'm not going to bend over backwards in order to accommodate the Heed, especially knowing that I can order the Sim 260T and return it if I'm not happy. Yes; I realize there are a variety of  transports out there, but I'll only consider purchases that include a return policy. Demoing gear in showrooms is a form of gambling I can't afford.  

Thanks again for your input.
