How to tell if Acoustic Treatment is Needed?
What Jax said! If the system/room interface provides you with what sounds like real/satisfying music to YOUR ears; COUNT YOUR BLESSINGS!! 
Variac differences and use
A unit like this(10A) would suit your purpose nicely: (http://cgi.ebay.com/PowerStat-3PN116B-Variac-Variable-Transformer_W0QQitemZ220451775080QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3353f32268&_trksid=p3286.c0.m14&_trkparms=65%3A12%... 
Suggestions for 'filling the port' of bass reflex
If you want to, "tone it down a little"; Go to a fabric/upholstery shop and get some (loose-not "felt")bonded dacron(http://cgi.ebay.com/Upholstery-Bonded-Dacron-Quilting-Batting-Padding_W0QQitemZ350220762258QQcmdZViewItemQQptZLH_DefaultDomain_0?h... 
Compatibly between Tubed and Solid- State Gear
Some tubes are noisier than others. I've made it a habit to only install tubes that have been tested, and certified/graded, "very low noise" for use in any stage before(or in) a preamp. Lector also hand picks low noise and matched tubes for use in... 
What do you see as the downside of tubes?
Exactly Fernando- I don't see ANY downside to tubes AT ALL. Your perspective will be based on your love for the sound of music. 
5AR4 rectifier tubes - Chinese or Russian?
If the Mullards are beyond what you'd like to spend, you might look into those Japanese Mullard copies. I've no personal experience with them, but if Kevin gives them his endorsement- that speaks volumes.(http://www.upscaleaudio.com/Japanese-5AR4_... 
5AR4 rectifier tubes - Chinese or Russian?
Your rectifier tube will have a marked effect on the overall sound of your unit. By going cheap there, you'll be ripping yourself off for a lot of music. If you went with a pair of NOS Mullards (GZ34/CV1377, from the Blackburn plant), they'd proba... 
Bad Hum Coming Through Amp, What Happened?
DITTO what Almarg said about a possible ground problem. Maybe a loose star ground, or a cold solder joint at a ground point. Definitely not output stage, because it varys with volume control. 
Aftermarket pickup tube felt
Valuable tip!! 
Aftermarket pickup tube felt
(http://www.musicdirect.com/product/74560) I haven't seen the felt separately. Here's an option:(http://www.walkeraudio.com/vortex_vrt.htm) And a review about it: (http://www.positive-feedback.com/Issue40/vortex.htm) 
amplifier needs
How loudly do you intend to play these extension speakers? If you won't be using the receiver at it's higher output capabilities; it's not going to have any "thermal runaway" issues. If you just intend to provide music at moderate volume levels, y... 
What amp do I need to power my Acoustat 1100
I agree on all points. It seemed the OP was leaning more toward SS, and thus my first response(regarding MOSFETs, high output, no thermal runaway). Knife fight? Bring an M-16(why waltz when you can rock 'n roll)! The AVA amps I suggested would sti... 
What amp do I need to power my Acoustat 1100
By, "wonders" I meant what I said in my initial post. Obviously eliminating noise is not a, "wonder". Here are some others that have found what I have with regards to the benefits of tube rolling in pre-amps:(http://www.6moons.com/audioreviews/tub... 
Dissapointed with my new speakers
You'd certainly think so, wouldn't you? Are they in the same room as the Klipsch system(living room)? Perhaps they are sensitive to their placement in the room? Have you tried moving them, with relation to the room boundaries? If they are in a dif... 
Dissapointed with my new speakers
Krell man is correct. The woofers' break-in can be accelerated by facing the cabinets toward one another(closely) and reversing the wires on one's input. This will put them out of phase with each other and cancel some of the sound. Pick some music...
