    Blue Fox, I would like to think we all have much to learn, so maybe you can help by shedding some light on this issue for me if you don't mind.
    What would one significant difference if I used a CD input source over a tape input source? Thanks!

    The inputs are exactly the same on the preamp/receiver, but tape is significantly more noisy than CD, and not at all my preferred material.

    Off the top of my head.

    1. Tape hiss.
    2. A CD contains digital files that are converted to analog via the DAC in the CD player. The quality of the DAC determines the sound quality of the file.
    3. A tape is an analog recording that is only as good as the tape heads, recording speed, tape format, and the associated circuitry.

    Just for clarity; I was referring to the actual RCA inputs and not the actual device.

    So if I plug my ipod into my CD input or my Tape input would there be any significant SNR issues????

    Ok, I'm not sure how you are measuring, but they can't be 10 feet apart on a 16 foot wall and still be 3 feet from each side wall. Measure from the inside edge of each speaker and set them up at 6 feet apart.

    Question; Do input sources have any impact on sound quality? CD vs Tape vs DVD?
    You mentioned in your other thread about having the best iPod library. Is that what you're using as a source right now?

    What kind of a iPod dock are you using? Where did you get the files on your iPod? What type of encoding format is used for these files.

    Plugging your iPod into either of those inputs is a moot point, since they will both suck. I guess you are interested in which one sucks the least. Try it and find out.

    The reason why it sucks is because doing that means you are using the $1.99 DAC chip in the iPod. Plus, I suspect your files use lossy encoding which increases the suckiness of the music.

    As a starting point, read this.

    Ah, you answered my question while I was typing. You need a better source.

    They're 7 feet apart from inside edge and not 10 as I originally stated.

    Yes, I'm using my ipod into my CD input using song I downloaded from itunes.

    Thanks for the insight.

    Summer, all this time I thought you were using a CD or a Blu Ray player to test these speakers.

    For two channel I prefer a simple system like I now have with a preamp and a power amp. I had an AVR before I had the separates and it was too complicated just for 2 channel listening. There were so many settings that even when I was listening in "Pure Direct" mode I was always wondering if I was still hearing a signal modified by the AVR or not. Don't get me wrong. I'm not a purist and I'm not above tweaking the bass or treble knobs every now and then. On my Pioneer AVR you had to make sure the front speakers were set to LARGE and it was set for NO subwoofer. Otherwise the bass would be weak.

    And using CD too.

    Thanks for all the feedback but I have yet to get an answer to my original ask; do RCA inputs (not the devices) CD vs DVD vs SAT/LD or Video have any significant SNR issues??? or as someone said which one sucks the least

    Thanks again.

    F1nut is right..first off the speakers are too far apart. No matter how your measuring them.

    I have SDA 1C's set up in a little over 13' wide by 28' long room. Plus i sit over 14' back.

    They are set at 8' apart if you measure from the outboard side of both speakers. They are also 1' off the back wall. Now that seems to work best in MY room....but if you move them farther apart..things don't work right. If you have a really heavy rug..you need spikes.



    Well the fact your using an AVR..not so great but again..put it back to 8ohms.

    The fact your trying to run a Ipod..with downloaded stuff from itunes. Well..that i have no answers for. You need to talk to the digital people.



    I have a separate Pre amp, amp and tube CD player..I have no problems at all.

    Default Adcom w/Sda 2bs

    My spred from outer corners of my 2bs is 7' and 1 foot off the rear wall. No side walls to deal with and my seating pos is at 9 ' center of my couch almost an equilateral triangle.Straight on,no toe in and I get great stereo seperation.I also share most of my sources w/ the exception of my tt.The Adcom 555, Sda 2bs and Yamaha rx-v665 works as a combo. Where the avr is lacking if just an avr are those sound fields that do nothing but add echo and or delay and it sounds terrible and is never used.Even in pure direct 2-channel it had nothing going for it.

    Good job.

    I had a Wadia 170 (still use it at work), and later upgraded to a Wadia 171, which sounds even better. I also have both the Bryston BDA1 and BDA2 DACs. In order for the iPod to be an excellent music source the files need to be copied from a CD as either uncompressed, or use Apple lossless compression. Any file bought from iTunes is a lossy file (musical data is removed to create a smaller file size), so you will need to build up your muscial library from scratch. However, I suspect that even the iTunes files will sound better through the Bryston DAC than the internal DAC in the iPod.

    I replaced my iPod wth the Bryston BDP1 digital file player, which is much more versatile than the iPod. It sounds a bit better also, but the iPod is still a great source with the Wadia and a good DAC.

    Same for the 667. Garbage for music, okay for HT and gaming.

    To be blunt IT DOESN'T MATTER there all line level inputs and should sound the same.

    Just don't use a phono input.
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Thank you, gimpod. This is one of those times where I had to read the answer in order to understand the question. It happens more often as I get older...or more senile...or more medicated.

    Update: I was finally able to access the GUI room set-up on my AVR with all effects off and settings flat.
    And for now Im using my Blueray player as a CD source. The SDA's sounds fantastic @ 25% vol.
    Now I can start tweaking.
    Thanks for all advice and support its much appreciated
