What Harmonic tech cables should I used for CD

It will depend on which DAC you think sounds better, If you use the RCA analog outs from the player then it's DAC's will be used..the digital out will use the DAC in your pre/pro. I use the digital out from my player because my Sunfire pre/pro sounds very good IMO. In some cases people report that they hear no difference between the two, my guess is that both DAC's are of equal quality in these cases.

I have a 1.5m run of HT Truthlinks. In both my system as well as my friends they don't sound as good as the Cardas Crosslink which is Cardas's entry level cable. I do like the HT speaker cable though.

I agree with Dave above as to what DAC sounds better to your ears as being the one you use. Often in mass market receivers the DAC isn't the biggest consideration when designing the unit. As you say, for DVD-Audio, RCA is the only way to go as your receiver will get a converted PCM signal if fed the digital from the DVD-Audio and you will likely lose something in the translation. Invest in some good IC's and you can move them to your next equipment purchases as you move up the food chain. Oh, you think you've bought your last equipment? Guess again. You're here on Agon aren't you?

Mr Cosmic, could you expand on your cardas/ truthlink comparison a bit...i had hoped the truth links would have done better than you suggest.

I have a pair on my CD and between the amp and pre. I've also used pro silway II in both places. I prefered the silways between the amp and pre but since in needed a 20 ft run a good deal on the truthlink drove me that way. on the CDP though the silways added some detail, tightened up the bass nicely, didn't adversely affect the mids but added a nasty high end glare that far outweighed the added benifits. CDP is an ARC CD-2, amps are VTL 185 monos with a VTL 5.5 pre

I had hoped the Truthlinks would have done better as well especially condidering what I paid for them. The largest difference is that the high frequency and upper mids are smeared and grainy on the Truthlinks in comparison to the Crosslinks. I use the .5m Crosslinks presently between my Cablebox and AV receiver. The Truthlinks are between my AV receiver L-R outs to my preamp surround pass through. I run Virtual Dynamics Audition IC's between the CDP and Pre and Amp. The Audition cables blow the Truthlinks out of the water. They are more balanced top to bottom and much quieter. Having said all this I am on the lookout for a 3m pair of balanced silver IC's for between the pre and the amp at some point. Apparently the Silways are out in a MK III version now and are supposed to have cleared up some of the glare. I have tested the Truthlinks in two different systems between the Cardas Crosslink and the Virtual Dynamics Audition IC's. My friend and I both rated the HT's as the worst of the three with the Crosslinks better, and the Auditions much better still. Some of this may be system dependent but as I said his is using quite a bit differnt gear from mine and the results were Identical between both. YMMV. I am glad that the Truthlinks are doing good for you in your system but would suggest that perhaps you explore some other manufacturer's cables if only for comparison's sake.
