How good is to use integrated amp as preamp with the preout feature


Dear Friends,

 

I have the Exposure 3010S2 Integrated and Accuphase Power amplifier. I like the sound signature of Exposure so I am thinking to add the Accuphase Power amp to it. I see there are 2 preout in the Exposure and I will use one of them to accuphase. Please note I don't want to Biamp as the sound singature may not match, hence its just the preout that I will be connecting to the poweramp.

 

Exposure 3010s2 Perout -> Accuphase Power amp -> Speakers

Is there any pros/cons with this setup, I still dont understand why I would need a seperate preamp when I can use the preout.

 

Thank you

The best thing to do is to try. You wont hurt anything. Be sure to have volume down when swapping use of amplifiers.  There are always gain issues. With some preamp/amp combinations there can be too much gain with the result the volume control has too little range of practical use, music getting too loud at low volume settings. 

Does the manual for the Exposure list the gain of the preamp section? What is gain of the Accuphase?

I agree and my accuphase powe amplifier has the gain settings. So should I go for a seperate preamp or this is good enough. I really dont understand why preamp is expensive but the integrated are not even though the preamp section of the Integrated has a very low circuit length as compared to external wires connecting to the power amp.

Your exposure most probably has a decent preamp section and a lackluster power amp section. The accuphase could be an upgrade.

When its power amp section is not in use, i.e., leeching off the power supply for the preamp (assuming they share the power supply), the preamp will also start to sound better.

You can put the streamer, dac and preamp in the same box. Guys like Borresen will tell you that it is in fact a better idea to do so. In many cases, having a seperate everything (streamer, dac, preamp, power amp strung along with unnecessary cables) will sound lousier in the end. The power amp is essentially the only thing that should be separate.

 

Given the Accuphase  has gain settings you can find a level of gain that matches well with the preamp stage of your integrated. I also believe the Accuphase should prove to be an upgrade.  Much will depend on how the Accuphase mates with your speakers sonically to provide the presentation you desire.  What speakers do you have?
