The weight of an amp results from the philosophy of the designer. If the goal is to have an amp that will linearly increase its power into low impedance loads then it's likely to be heavy. In addition, if the designer prefers Class A bias then that will also add to the weight. For example, I have a Krell KSA 300S that provides 300 watts @ 8 ohms, 600 watts @ 4 ohms, and 1200 watts @ 2 ohms. Very few amplifiers will do this. There is also a automatic biasing feature that causes the amp to run in Class A mode up to high wattages. It weighs 185 lbs.
So why do I need all that power into low impedance loads? Because I run Thiel CS6 speakers that have low sensitivity (87db) and their impedance drops to below 3 ohms for parts of the audio band. This is a brutal load for an amplifier. For a speaker load like this the amplifier's capabilities will make a big difference in how the speakers sound.
Your Klipsch speakers are on the other end of the spectrum compared to my Thiels. They have 102db sensitivity which is very high. You would be fine with an 8 watt Single Ended Triode tube amp if you wanted to go that direction. Because your speakers are easy to drive you have a virtually unlimited selection of amplifiers.
If you had a bias toward tubes (pun intended) then you could go with any number of beautiful tube integrateds or separates. You don't need any more than 30 or 40 watts to shatter the windows unless you have a very big room.
If you are smitten by the appearance of gear then I have a word of warning. Don't look at the Line Magnetic LM-845 Premium integrated amp. It's necessary to see it in person to get the full effect (by the way it's really heavy). It's a little fat for your price range but you may sell the dog and take out a second mortgage to buy it. It wouldn't run my speakers but it's perfect for yours. The LM-845 may be the most beautiful piece of gear I've ever seen.
