I think you'd be fine with the Kilpsch or Ultimate ears, wouldn't go too wrong IMO.
Mostly folk, rock, some classical and a bit of electronic stuff. Primary source would be a portable MP3-Player. I'm looking for something in the lines of Klipsch Image S4, UE super.fi 4/5, Sennheiser CX 400 II. Right now I'm using a pair of Sony MDR EX85 LP, which died on me yesterday, and some old Sennheiser CX 300, which I hate, as backup.
My favorites so far would be the Klipsch I guess..
The receiver does have a distance setting, but what I would like is some way to test it.
The AU-999 is the most advanced professional control amplifier ever manufactured by Sansui.
Designed specifically for the ardent audiophile, it features the refined dull black panels common to all AU series professional control amplifiers from Sansui.
The pre-amplifier section is constructed of carefully selected low-noise PNP silicon transistors, while the power amplifier section features direct-coupled circuits specially developed with the improvement of tonal quality in mind.
Together, they permit the AU-999 to deliver a full 180 watts (4 ohms) in music power output with unprecedented tone quality.
The AU-999 is lavishly endowed with accessory circuits.
These include a tone selector circuit, an improved form of the triple tone control circuit that offers a choice in selecting the critical frequencies of tone control; a speaker selector which permits connecting three sets of speaker systems; a balance check switch which simplifies the job of adjusting for optimum balance of the right and left channel sound volumes; facilities to connect two phonographs and two tape decks, and a tape reprint circuit.
Special provisions have also been made to permit the amplifier to be built up into an electronic crossover stereo system and permit comparing such a system with a standard stereo set-up.
Power output: 50W per channel RMS [at 8 ohms, 70w @ 4 ohms. -CJ]
Total harmonic distortion: less than 0.4% at rated output
Frequency response: 5 to 100,000Hz
Channel separation: better than 50dB
Load impedance: 4 to 16 Ohms
Damping factor: 45 at 8 Ohms load
You could create your own test sounds. Assuming the theoretical delay is somewhere in the 5ms range, play a sine wave, let's say 100Hz, on the front left speaker while you're playing the same tone on the back left speaker with no delay in the receiver. If you hear nothing then you need a delay of either 5ms or 15ms (unlikely). If you heard something, shift the tone playing at the back by 1ms forward/later, if you hear nothing now you either need 6 or 16ms (unlikely). If you heard something, shift the tone at the back to 1ms earlier, if you hear nothing now you need 4ms or 14ms (unlikely).
eizbaer, do you have any baffle step compensation and high pass filter on your W4-657sc's?
I have them unfiltered at the moment, but I was wondering if they need any. (baffle-step for improving sound, and high pass for protecting the element)
