  1. Who to point the finger at???

    When running full-range 2 channel, you're at the complete mercy of room acoustics at frequencies below 200 Hz and even up to 500 Hz in some instances. EQ is the only weapon of choice. As for the hot midrange two things come to mind: 1st reflections from the squawker coming off the floor (if it's not plush) and if you haven't got the bass sorted out, the mids will always be more pronounced. What are you used to listening to before the big K's?
  2. I can only imagine how well an analog source could sound if we were to put as much time and effort into that format.

    An analog source isn't the problem, it's the analog gain structure during playback that presents the lion share of problems. Keeping it clean, undistorted, and driver-friendly from one side of an amplifier to the other is PFM.
  3. None of the people recommending against using L-pads could give a technical reason for not doing so, and electronically speaking, I can't think of one either.

    See Al's last bullet statement here: http://www.alkeng.com/pad.html

    You have to run the math, but it is possible to drop the damping ratio too low (less than 20) using an L-Pad if a network isn't intended for one.

  4. I never understood 4ft tall 100 lb speakers set to small, it's obvious they are not.That said ,always try different settings.

    Trying different settings won't cut it flying blind. It's all in the acoustics. The real solution unfortunately is not a 4ft tall 100 lb speaker, at least in the home. But if you happen to have one and want it play well with a sub [to take advantage of the response afforded by doing so] , you have to set it to "small" to command the receiver to use it's internal filters.

  5. The most realistic recording of an orchestra would use a matched pair of mics in a binaural in-the-ear arrangement (only to be played back on headphones) or a matched pair mic setup that cut the line of sight to the "virtual listener" prescribed in the Dolby arrangement for 2 channel listening. It's purely a matter of superposition. To blend more than 2 mics for a 2 channel recording will introduce a whole lot of instrumental phase problems that the mixing engineer will have to sort out. ie. Why try to mic a xylophone when the conductor has beaten the percussionist over the head enough times to make them sound just right. In fact, if you wanted to make a heck of a recording, try placing the microphones at the podium...to hear what they hear.

  6. How satisfied are you with it?

    VERY satisfied. Once levels are set, the chirps and analysis (the hard part) are fully automatic. Set the sub delay based on the results, pick you're crossover point on the receiver and pure ****'ing magic.

    The AS-EQ1 will suggest a crossover point for you (40Hz in my case), but you don't have to use it (I use 80 Hz, low as my receiver goes). Seeing that the passband phase response is linearized after the correction, you are free to choose a crossover point based solely on your main speaker's frequency response. You will not be disappointed.

  7. Picked up a couple more XR's (including the elusive SA-XR700) and had to put them through their paces. What better way to test them out than by dusting off my old college dorm room speakers with some Telarc and DTS at 90dB ? Just cobbled the system together to test the receivers, and didn't take the time to really dial things in. Thought I'd get my 14 year old budget-rig on video before they dry rot. They aren't Klipsch, but I was in college and got the whole system new (on clearance) for what I paid for one LaScala.

    Cheers!

    PS - Can't help but think the XR-700 looks kind of "McIntosh" but without the green.

  8. Davis and I agree you can never have too much power.

    Yes you can. You can have so much much gain in your system that the noise floor becomes audible at the system's lowest setting. It's a real problem...and you can't turn down any further. Bigger ain't always better. Just over 20dB is plenty for the home IMHO, and if you want louder, find a more sensitive speaker.
  9. I am not asking if they can go loud as they obviously already know they can, but if more powerful amplifier will have stronger bass and more dynamic on a moderate volume level.

    Not unless you're at the amp's limit at those quiet levels... What your asking for, more bass and a phat tone at low levels, is accomplished by using EQ or bi-amping. Put the power to the drivers that can correct for your ears at low volume.
