Question regarding adding a poweramp to an integrated amp


Greetings, 

If I added a powered amplifier to an integrated amplifier via preouts, would the internal amplifier on the integrated turn off? Or will it still run and generate heat regardless?

 

I have a Lexicon RV-5 and love it and it’s functioning fine, but I am concerned at the age and the fact that nobody wants to touch it in regards to servicing it.  I wanted to get it recapped and even pyramid audio won’t due it. Basically I’d feel more comfortable buying a poweramp if I knew I’d be preserving the internal amplifier.

Well, one way to look at it is, if it can't be serviced anyway and you want to run an external amp, what would you be preserving the internal amp for?

Does the owners manual show anything about this?

To answer your question, the amplifier portion will NOT turn off.  I believe it is class AB power, so it will still continue to continue to generate some heat, but not to the level of a class A unit.

What you don't mention is if you are using this for 2 channel or multi-channel/home theater.  If only just for 2 channel, you are better off just putting the money into a new (or new to you) integrated amp.  Most likely it will have a better preamp section than Lexicon's bottom line home theater receiver. 

Also, I seem to remember, but don't hold me to it, that Lexicon got criticized for the RV-5 because they just rebranded/borrowed the internals from someone elses home theater receiver, similar like they did with Oppo's blu-ray player.

I have a Cyrus integrated amp.   After buying new speakers 50 watts wasn't quite enough so I picked up an amp and ran it off the Cyrus Integrated amps RCA preouts 

The integrated amp runs my REL sub via it's speaker jacks and runs super cool.  The new amp drives the speakers , worked out great.
