I am considering these options for volume control for my soon to 
arrive new system:

1. Monitor. My Genelec 8030A has volume knob. I would guess, this 
method makes least noise...?

2. External mixer

3. Volume pedal

4. Some module capable of attenuating. For example, Analogue 
Solutions HP01 headphone amplifier, which takes only 6HP:

"It has three main functions;
Small mixer to take outputs from other sub-mixers in the system.
Headphone Pre-Amp for those that wish not to use speakers.
1/4" / large jack output so the main output signal from the system 
can be taken to a mixing desk without the need for special cables or 
adaptors."
The discontinued A-139 has only headphone outs...
(By the way, is it safe - for the equipment, not to ears - to 
directly monitor modules with headphones? Mine are 2 X 100 ohms.)


I would like to hear, how you more experienced people deal with 
volume control and what you use for amplification?
