Which IC is more important?


I don't know if this has been addressed specifically before, but I couldn't find it searching thru the cables forum. At the risk of being redundant, I'll put this forward to the community.

Looking at a CDP - line stage - amp sequence, which of the two IC's is more critical? Any reason, scientific or other, as to why? What have your experiences been in using different IC's in these places (ie. type of IC, quality, cost, etc.)?

Looking forward to hearing about your experiences.

The interface between all components is obviously critical, I think everyone agrees with that - for me the preamp/amp connection is the most critical and I proved it when I did extensive auditioning of cables. I noticed a bigger difference when swapping out that interface vs. source to preamp. Can't say why but it was...YMMV
A couple of comments have implied that I'm trying to take short cuts to "audio nirvana" by putting up this post. I'd like to make it clear that I am not. I am trying different stuff on my own, in different places on my gear. It's been, and always is, great fun and a great hobby.

If you construed from my comments that I'm looking for advice like "Hey, try cable XYZ that costs ABC dollars at your source because it'll sound good!", then my question and dialogue should've been more clear.

Your input is great, long or short. I don't believe longer is better. I'd love to hear about your journey in getting to where you are today though.

I'd also like to share with you about what prompted me to post this question. I swapped cables X and Y in my gear, and after letting them settle, I concluded it sounded horrible in that configuration. Putting them back the other way sounded good again. Obviously something is afoot...little cable elves got upset???
Thanks for clearing things up Mapleleaf. Sorry if it seemed like i was jumping on you or "nagging". It was not intended that way but may have appeared as such.

As to Pop's findings about the cables between his pre and power amp making a BIG difference, that should be obvious to all involved with this hobby. That specific interface will affect EVERYTHING in the system. Unlike changing the cable for just one source, ALL of the various source signals AND the preamp have to pass through it. That's why i posted a link to "voicing your system" over in the Cable Asylum. Knowing what cables to change and when to change them can make a WORLD of a difference in terms of budget and system synergy. Sean

Thanks for your comments Sean. I appreciate any constructive criticism. At least you didn't resort to juvenile antics to admonish. I would like to be a positive person here, and not one prone to hissyfits or negavitism. Always enjoy your input, and read your link with great interest.

I've got a really simple system. I have a source, line stage, and amp. So theoretically, swapping cables here should be "equal" in terms of impact, right? I've found that this is not the case, so there must be synergy or something here at work.
"The upstream cable is always more critical because it affects everything downstream." No! It really comes down to how each component integrates with the rest of the system. And some links in the chain are far more critical than others. All this said, in my own experience, I can put a cheapo $30 Canare or Belden XLR 1m cable between my phono (ARC PH2) and line stages (ARC LS5II) and a multi-thousand$ NBS Statement XLR cable between my line stage and amp (ARC VT130) and this works incredibly well. If I reverse these cables, all of the magical ambience and resolution brought on by the NBS is GONE! The line-to-amp link is just a lot more critical in the context of my system. It's that simple. Whatever science or theory or salesmen or magazine reviewers may tell me, my ears tell me a different story to what I would have expected. And putting another expensive cable in the phono-to-line link makes a very minute difference....so I don't bother with one in this link. Of course I would love such a cable to bring on another level of performance here, but it just didn't happen. Was I disappointed? A little as I wanted more....and yet I saved a lot of $$ in the process. Maybe it's the output/input impedances between the connecting components, the location of the components in the room, etc., I don't know. But I don't make any blanket statements as to what is "best" or "always". You just have to borrow a few different brands, perhaps many pairs of each, start with one brand throughout and then swap a link at a time and see what cables works well in each link. Some cheapo cables just might outperform very expensive ones or at least be so darn close that you recognize the value. Don't be afraid to put a $30 cable in between $10k of components. And don't be afraid to put a very expensive cable between less expensive components. The prices on some of these products often has nothing to do with their musical virtues so try all combinations you can. And don't be concerned about staying with one brand of cable. That's another misnomer. Hope this all helps.
