Hi Alan-
Thanks for the very thorough reply. If i understand it correctly, the Lynx sound card is used to convert the signal to a useable AES/BSU type and the AA still acts as the DAC (and preamp). A very simple solution and the Lynx L22 is a little less expensive and offers only audio functions.

I am new to the Mac world with an iMac now, but will have a dedicated music computer when I get it all together to launch this pc system. It is not quite as apparent how to install the sound card into a Mac, but I am sure I could get the help I need....I may need to use a Mac pro, which is far too expensive for this endeavor.

Is it necessary to use the Lynx cables? I guess the more important question is do different brands of the same type of cable sound differently if they are just carrying digital information?

I have also had the AI Modulus 3, but didn't own it for long. It was a bit thin and a little noisy for me. The AA seems like a logical step, but the idea of using the equipment I have now is also seriously appealing. If I could only afford to have both and a/b them, I'd be set! Why do you also own the Transcendent?

And, by the way, great photos! You should offer them up as screen savers....selfish of me, I know.

Best Regards,
Art

  Hi Art,

  I can't imagine how one would get a PCI sound card into an iMac. I think you would be limited to using an optical out from the iMac, or buy an external DAC which supports USB or Firewire. Yashu's suggestion of the Trends UD 10 looks good also, but I have no experience with the device.

  Regarding cables for the Lynx, other companies do make cables snakes that will fit some of the Lynx connectors, and other Lynx users have brewed their own cables. I have only used the Lynx cables so far. I am not one to get into the discussion of whether different cables sound the different carrying digital information, but the digital cable is not carrying ones and zeros, it is carrying an electrical representation of ones and zeros in the form of a varrying voltage.

  I can hear some differences between differing digital inputs on the same device, but of course using different inputs requires different cables, and I don't know if the differences are due to the output on the outgoing equipment, the input on the fed equipment, or the cable type. I generally stick to purchasing well constructed, good quality cables over using cables as a means to tweak the system sound. A good, judiciously applied subtractive parametric EQ allows me to get far better results over playing with cable configurations.

  I own the Transcendent Sound preamp because I like to build things, and it is one of those pieces of equipment that sound far better than I could ever sell it for, so I keep it for my second system.

  I think I may have given the wrong impression in my earlier note when comparing the sound of the Lynx DACs against the Audio Aero. I said the Lynx was slightly more harsh, but I don't think that is correct. I went back and listened again after writing the last note. The difference is more of a fleshed out midrange and more midbass warmth with the Audio Aero. I don't think the Lynx is more harsh, but has a different balance due to the lack of tubes. I will say that the Lynx is more transparent, and that transparency can lead to a bit of harshness on poor recordings. The Lynx has a slightly more etherial sound, with less instrumental solidity than the Audio Aero, but on good recordings it does sound very nice - much better than the other internal sound cards I have played with.

  Good luck with whatever you choose, and have fun!

  Alan

    Hey AJ,

    Based on your listening, do you think if there were tubes in the system some other place, say a tubed pre-amp, that you would get the added transparency of the Lynx and the mid/midbass warmth of tubes??

      Hi Dawnrazor,

      Most likely. I'll try it. It will be a very easy thing to do. I'll run the digital out from the Lynx into the Audio Aero digital input, and a pair of analog outs from the Lynx into the Audio Aero analog input and make a comparison between the two. The analog inputs of the AA doesn't convert analog to digital and back again so I should be able to compare the merits of each DAC and more precisely see what affect the tubes in the output stage of the AA have. I'll also try going from the Lynx into a different tubed preamp and see what affect it has. I'll let you know.

      By the way, if I haven't made this clear, the bass warmth of the AA is really a trade-off. It is the typical tube / solid-state argument when comparing the Lynx to the Audio Aero.

        Hey Aj,

        Thanks for the info, and let us know how it goes.

        I did think your posts smacked of the ss/tube debate. That is why it would be interesting to see if you could have your cake and eat it too.

        One day, i will get around to making a cable box for the lynx and use some home brew cables to see if that offers and improvement. The stock cables sound good to me, but I think that may improve things even further.

        Cheers.
