Hi, please let me know if there is another thread that I should check into.  I just got my brand new XPA-9, and I am wondering what is the first thing I should do in terms of getting the full potential of the amp.  Should I redo an Audyssey calibration (via the Denon X4100W) using 0.0 db as volume or is there a different thing that I need to do?  How about breaking the amp in, is there such a thing or is it necessary at all?  Any recommendations and advise are much appreciated, thank you for your expertise!!

Hi Thomas. Congrats on the new amp!

You should see a big improvement in sound quality and control with the addition of a power amplifier to power your speakers through your AVR.

I remember my first power amplifier was the XPA-5 that I connected to my Yamaha receiver pre outs. What a difference. I haven't looked back. It is certainly the way to go if you want the full featured and stable platform that the big name AVR manufacturers put out. Once you get a taste of that sweet sound, you may want to try the full upgrade to separates with a home theater processor.

I'm glad others helped you out with your setup. There are some great people here.

Enjoy your new equipment!

Guys, I want to further calibrate my system now that I have my Emotiva set up. I also went and got myself a SPL meter, now, I read a lot online regarding this procedure, there is one thing I am a bit confused and hopefully some of you can set me straight on it. Once you have Audyssey did its thing with the initial calibration, then I setup the SPL meter (C weight, Slow, and Range at 75db), place it on a tripod at the MLP, now, do I go to my AVR's Test Tone screen (Denon X4100W), and turn the volume knob up until it is at 0db, then adjust each channel (another word, adding or reducing output that were previously set by Audyssey), so that they all read 75db on the SPL meter? Please advise if my understanding is incorrect, thank you all in advance!!

There are some videos online saying you have to set all the channels to 0db initially then adjust with the SPL meter; wouldn't that erase everything Audyssey did?  Or are they skipping Audyssey completely?  This is the confusing part!

Actually if you had just inserted your new amp into the mix without doing anything else the only thing different is where the volume display (in db) is when at your normal listening level. With the new amp it may have been up by a few db since the XPA has more power. It takes double the power each time you want to crank up another 3db of volume. And since your Klipsch speakers are quite efficient I wouldn't expect to hear much difference, if any, in sound quality. You might hear some difference in 2 channel for music.

Yeah, I did notice that I need to crank it a bit higher to hear the difference.  But that's not what I am seeking help for, I just want to do a refined calibration now that I have a SPL meter so that every channel is at 75db.  My query is should I do a Audyssey first then go into Test Tone with volume turn up to 0db then test every channel with the SPL meter and adjust the Audyssey results?  Or is there a different but correct way to do this?  Thanks for any advise and recommendations!!
