Power Amps - advice needed

Could someone please clear up for me the differences between an integrated amp and a Power amp.

Is it correct that if I attach my CD player to a power amp then the musical sound output is that of the CD player without any 'colouration'.

Whereas if I attach it to a integrated then the tone is affected by the amplifier.

Hi Ian

An integrated consists the pre amp ( Volume control and input selectors ) and Power amp ( which drives the speakers ) in one box... Where ever you need a power amp you need the means to have a volume pot whether from a pre-amp or a CD player with a variable output... If your CD player has a variable output you can use a power amp directly... Although the quality can vary between players.. A CD player like my Quad CD-P2 has a proper digital volume control with digital inputs as well, which does reap huge dividends in sound quality stakes....

A few demos from your local hi-fi specialist shops would put you on the right tracks...


Goodluck

Tim :)

Ian, an integrated amp is a complete solution for amplification. It takes care of volume control, different inputs tone controls, power and any other options you may require. A power amp has only one function: 2 volts in, maximum power out. To use a power amp, as Thekop says you will need a cd player that has a variable output (not too many around) or a pre-amp that will take care of everything an integrated does except for the power. Pre/power combos tend to be 'high end'. You pay more for what can appear on paper to be similar performance. In so saying I did the variable cd into a power amp thing. It was very good!:D

The thing is I only need the one input. It is for a bedroom upstairs.

And hopefully tone control should not be a problem either given the rave reviews that the Unico CD has got and is supposed to be naturally bass heavy which I like.

I have a Nad C270 stereo power amp and although the CD player does not have variable volume control, the Nad power amp has two sets of input r/l sockets.

One set is labelled 'variable' along with a volume dial for said inputs and the other set is labelled as 'fixed' input r/l sockets.

So I am assuming that I can adjust the sound levels using the power amp.

I would like some reassurance that I will not damage the Unico CD player in any way and confirmation that I should get the CD sound 'uncoloured'.

Has anyone else used the NAD C270 power amp in this way ?

Either the power amp needs to have a variable input, or the CDP needs a variable output - something has to control the volume. Sounds like your amp does the trick here.

Don't get carried away with the "uncoloured" bit though. Every component has a sonic character and nothing is entirely neutral. The key is matching the components so they produce the sound you like.
