    current vs. voltage amp output

    could one of the "engineer" types out there help me to understand what the difference is b/w an amp with a current and a voltage source on the output stage, what it actually means and how it effects speaker performance? I am referring to the Sunfire Stereo Signature amp. It is being used to push...

    component sub driver choice

    OK, Brian, I will be more specific. The Sunfire amp puts out about 2,00 watts into 2 ohms. 10^ft is bit large. I am thinking more on the line of 2 - 2 1/2^ft ported.

    component sub driver choice

    It will be used for both movies and music. Cost is no object, and the amp is a Sunfire Signature Stereo which is quite powerful. I would prefer a ported box.

    component sub driver choice

    Here is a question that should bring about a wide variety of opinions. If you were going to build a sub for your home which driver would you choose and what type of box would you put it in,i.e., ported or sealed? Thank you for any feedback you have to offer.

    A/C power cable upgrade

    I have been trying to locate a supply of A/C cables for my CD player, pre-amp and amps for a while now. I have seen the mega $$$$ cables on some other sites but they are beyond my means. I do want to upgrade them, why else would they be made removable? I would not use the RCA cable that came...

    Best Pre-Amp in the 3-5k range

    Why has no one mentioned the NAD S-170? I use it and so far I have found it to be a pretty good unit.

    TV can't handle S and coax video at the same time

    There is a switch box available that has 4 a/v inputs, L-R audio,composite video and s-video with the same options on the output. This should solve your problem for less than $50.00

    denon 3800 info request

    after reading the response from the prior thread I ask myself - why would I buy a $1,200.00 dvd player (denon 3800) when I can get a $500.00 (denon 1600) that does not have "the bug"

    Pre-Pro choice HELP!

    Would it make sense to anyone if I used the above Elite unit as a pre / pro? It does seem to have all that I need, I just wanted to get more power so I figured an external amp (ATI) with 165w/ch would do it.

    Pre-Pro choice HELP!

    Thanks Angelo and Bob. When I mentioned the x-over I meant an overall setting as you mentioned above. As far as cost goes I figure about $2,000.00 would cover what I need. This would have to be after I sold the Elite and Sunfire units!
