Preamp necessary? Questions

[zumbo]

What I'm wondering is if the amp will have an easier time running a 4 ohm speaker than an 8 ohm one, or will it not make much difference? Of the little I remember from electrics class, it seems like at 8 ohms there would be less power put out readily. Would it still put out a decent enough amount of power at 8 ohms compared to 4? Pretty much everything I'm looking at is rated at 8 ohms, so I'm fairly curious.

Oh, and the headphone situation is not a problem. I have a portable amp that I use for now, and am planning on getting a HB1 to sit in the office alone soon enough.

It will be easier on the amp running 8ohm speakers. Look at the speaker sensitivity rating of the speaker for loudness.

It isn't easier to drive the 4 ohm speakers. Speaker with low impedance require the amplifier to give them more amperage than higher resistance speakers. So a 4 ohm speaker requires that the power supply of the amplifier be up to the task to deliver large amounts of amperage, so it is not easier. But you say you won't be blarring it, and 4 ohms is within safe operating range. You should be all set now.

Klipsch may work well with the BPA-1. They have swinging impedance, and excellent efficiency. The amplifier should be able to take the work. Only thing with Klipsch is the revealing factor, they may show faults in compressed audio from a computer, only good MP3s would do here.

Klipsch $u(k!

Arg, you guys are killing me!

Someone please look at the link in post #9 that way we can progress on this thread,...PLEASE!

Forgive my impatience gentlemen, but it is like you are just reading the OP and answering the question without research.

Most amplifiers, unlike the Emotiva BPA-1 have fixed inputs that when paired with fixed outputs from sources such as a DVD player or CD player would result in catastrophic damage to your speakers or amplifier. But in the special case of this BPA-1, it has volume control. The amp can be used as a stereo integrated amplifier with no tonal controls or switching abilities, or you can bridge the amp and use it to power one speaker, or you can use it as a complete subwoofer amplifier (it has a selectable, variable low pass x-over) and also can be daisy chained to other amplifiers using the output.

I thought you were being sarcastic for a second, then I read your post.
