I was thinking something like a fixed value attenuator , but I'm not sure if they can be used in this way or not(maybe call PE).

I never seen those before. I like them a whole lot better, much easier to work with. I'll probably order a few in a couple of weeks to play around with.

Sure, Brian; even a half dB difference over such a wide frequency range can make a perceptible difference. That's why one of the requirements in a blind test is to match levels to within 0.1dB so that a slight loudness difference isn't misinterpreted as a quality difference.

in my experience, changes as small as +- 0.05 dB are distinquishable (.1 dB overall)

I went to do some more adjusting to the EQ setting. I noticed that my Harmony Logitech 1100 was not responding on every button press on the touch screen. After rebooting it about 3 times, I noticed that most of the time it is the button to the right of where I touched that got activated.

Great. I bought from Best Buy on 04/15/10 and the 1 year warranty has expired. I guess tomorrow I'll need to pull about $350 out of savings and go buy another one. I use the stupid thing a lot, probably wore it out, but for $300 you'd think you'd get more than 13 months of use out of it. Next time I'm buying an extra year or 2 of warranty.

Or you can get the harmony one or the 900 if you need RF. The buttons will be more durable than any touch screen.

But, can I access all of the AVR, TV, and BR functions with it? With the 1100, I see all of them on the touch screen? I can even program it to turn my fan, and heater on or off. As long as it has an IR remote.

My equip is in a different room, so I definitely need RF. I already have the remote unit for the 1100.

One think I very rarely use is the numerical keypad. I don't use cable TV. That's one of the things that take up a lot of real estate on the 900. It looks like the price of the 2 are about the same now. I'll probably get another 1100 with extended warranty unless there's a really good reason to go with the 900.

The only good reason that I see is to have the hard buttons. The 900 controls up to 15 devices so it will control your equipment the same as the 1100 does. You can program any of the hard buttons to do any function so if you don't use the numbers on the keypad, you can program them to do something else. Even if you don't watch TV, I'm sure you press a lot keys like: volume, play, pause, forward, back, arrows when you go into your AVR Menu, etc..
In the end it's a matter of preference, I just prefer hard buttons and the way the 900 can be handled with one hand.
One thing to keep in mind is that if you switch to a different model, you're gonna have to reprogram most of the remote. When I went from a 720 to the One, it kept all my devices and activities but I had to reprogram the functions of each button.

Too late. I already bought the 1100 at BB today. It was still priced at $399 in the store. When I told the sales girl that it's much cheaper on-line, she said she could sell it at that price. I got one for 272.99 + 40 for 2 year extended warranty.

That was a good price and obviously a wise decision on the extended warranty.
