The key is to get a high voltage output at the AVR pre-outs with low distortion. Otherwise the amp is just magnifying an input full of distortion. This beats the purpose of using an amp.
When I had my Rotel RB-1080 with my Denon 3010 and Klipsch speakers, I noticed no difference between using the Denon as an amp or using it as a pre-pro for the Rotel RB-1080
One reason people use separate amps like for the front L/R/C and use AVR for the surrounds is to take some load off the AVR. But in a 2ch set up, the difference is going to be very subtle as it was in my case.
I understand what you are saying........ My Cornwalls are only 6.5 feet away from my sofa and 6.5 feet apart. I am looking for a 5 channel amp that will deliver the same loudness as my meger AVR amps.
I don't hear any distortion at 90DB/100 peak special effects when watching a Bluray movie. I just did a test with my DB meter and my display on the AVR shows -10 at 90 DB This Yamaha goes to +20 MAX that in
4 years I have never gotten close to. So my point is if I only use 75% of my AVR pre amp that it will send to a 5 channel amp it should be distortation free. Yes I see that I will not be sending 1V to the amp at this setting. And miss out on some of it's power(that I don't need) in this small room.
I hope someone that has my AVR and 5 channel amp for HT will post up on my thread on AK forum and give their thoughts on how it sounds at 90DB. Lets say I don't notice any difference with the XPA5 at 90 Db......this means
I will have the same GOOD sound I have now. And my AVR will not get so warm after several Bluray movies with the amps not being used....
When this AVR finally dies I will look at a seperate HD Pre/Pro for the 5 channel amp. Upgrade in two stages is what I am trying to do.
I wish I could afford a new high quality HD Pre/Pro and a matching 5 channel 200watt amp at one purchase. I have to save up and get them one at a time. For the money the UMC1 was a great deal..... too bad it soo many bad problems. Maybe the UMC2 will not have any HDMI switching issues. Time will tell as I am in no hurry... saving my $$. I almost had enough for the XPA-5 that was on sale now they are gone and the price is higher for the gen II. I will look into the Shearbourn 5X200 and their Pre/Pro for a future purchase.Edited by Louis Bartay - 7/10/13 at 11:46am
