Passive Pre-amp: Improves overall sound quality??
Atmasphere, I am not sure I understand the "5. = control the effect of the ic" if it isn't already included in the 4. ie the low output impedance sees the ic's impedance+amps input imp. 
Passive Pre-amp: Improves overall sound quality??
Lets list what a preamp does:1. source selection2. voltage gain3. attenuation4. buffering (impedance matching)5. tone control (older preamps,typically)Now, it is up to user to define his needs,since "the simple is the better" (or Okahm's razor) pr... 
a solid state amp that is recessed in the treble
I have both the esl57 and mg1.6! 909 works fine with both of them. But, it is difficult to find the pre that matches, since Quad 99 is not up to task,while input impedance (20k) of the 909 is not quite comfortable for tube pre. After 10 years of t... 
Amps for ESL
do yourself a favor: try a QUAD amp (909,606,306,303 but not the 99!) it will sound better then most other amps costing 10x more. However, you should avoid Quad preamps!For more then 30 years i've owned 57,63,988,2805 with CJ,Electrocompaniet,Bedi... 
Is there any truth to this question?
quad 306 vs quad 606(909)pass labs aleph 3 vs aleph 5pass labs x250 vs x600bryston 4bst vs 7bst and always smaller sounded better !(speakers: quad 63,988,2805,57; mg1.6,mg12,mg 3.6, gradient Revolutions} 
Quad 99 preamp/909 amplifier combo
the 99 pre does not have the level of resolution the 909 has! For example: you could not tell the difference between the mediocre CDplayer and the better one listening through the 99. I replaced it with passive pre. the 909 has high gain (around 3... 
Who makes the best passive volume control?
i duno if they are best, but they are certanly very good:(using them for more then 3 years with various amps)http://www.positive-feedback.com/Issue19/endlerattenuators.htmorhttp://www.icl.co.jp/audio/english/Model5/m5-1.htm 
What tube amps for the Quad ELS 63
II40 or 909.for the period of more then two decades I have tried various ss/tube amps for 63,988,2805 and to my ears they work best with Quad electronics. I owned CJ pV5/Mv50,electrocompaniet,counterpoint in the eighties,then Krell,Pass Labs,Bryst...
