Matching digital input impedance of dac with cable

Since we're on the subject, I've seen DACs with 75 ohm inputs & others with 110 ohm inputs. Is there a performance difference between the two other than the 110 ohm input is easier to drive for a transport?

Tplavas & Audiofeil,
Thank you for the information. There is no such thing as too information until it starts to get confusing.....

I currently have a Classe CDT-1 transport connected to a Krell Showcase Surround Preamp/Processor via a Monster 600 digital cable; I'm using the Krell's on-board DAC. At times & with less than great recordings, it sounds abit edgy. Does anyone have suggestions on a good digital cable < $300? Any experiences with active cables vs. standard?

Tplavas,

I am going to try the Chimera Advantage Series II Single Ended Digital Cable. After I let it burn in, I'll let yuo know how it goes; probably sometime in August.

Thanks for your help.

I've been breaking in the new Chimera Digital Cable for about 3 days now and it has absolutely put the Monster 600 digital cable to shame. I'm hearing components of the music that were just hinted at before but now are more defined and forward. Some of these notes/instruments I had never even heard before. WOW! The notes sound more real with that "air" everyone talks about. And the soundstage, Gadzooks! It has almost exploded in size & depth and, get this, the detail has increased. I sit about 9' from my Martin Logans & there were notes coming out at me. One instrument felt close enough that I could touch it! It was coming out at the 2 O'Clock position about 4' away from me. I have never experienced that with my system. The bass is so much fuller while maintaining the punch. The highs are much easier on the ears, but still have alittle work to do.

All in all, it was well worth the investment <$180. In fact, I'm so pleased, I'll be budgeting for addition chimera cables for my amp.

The cables are continuous copper core 25ga multi-strand Linz-based topology.

Tboooe,

Sure. I have a Classe CDT-1 connected to a Krell Showcase Surround Preamp/Processor; Using the Krell's on-board DAC. I don't know what Burr-Brown DAC Chip is used but it's 24-bit with upsampling to 192kHz.

As for the cable, I had read several reviews & description of Litz Braid cables. From what I understand, they help with the high freqs that travel along the outer surface of the cable conductors. Here are a couple sites that make these types of cables (one silver, one copper).

Dennis Boyle of Chimera was very helpful & responded to all my questions via e-mail in a timely manner.

If you're happy with Acoustic Zen, why change. There's comfort with the familiar.

Hope that helps.
