Question about Gain, amp power and volume

newbee - do you think i would have this problem even if i had lower powered amp say around 70 to 100w, also i only use cd, i was under the impression most cd players had about the same output, is this true or am i incorrect, thanks for the input - mike

Mike, Its not about the power output of your amp, its about the amps input sensitivity. An amp with a high input sensitivity, say .5v will present problems if you have highly sensitive speakers (the higher, the more problems, including hearing residual noise from the pre-amp - tube amps are especially sensitive to that). Amps with lower sensitivity, say 1.5v work better with pre amps and speakers with higher sensitivity. By using the in-line attenuators you have probably reached the same result as using an amp with lower input sensitivity. If you had a speaker with an 86db figure you would get several more clicks on your volume control. Its all about matching preamp output gain, amp input sensitivity, and speaker sensitivity. As to output from CDP's and DAC's they definitly differ, and greatly. I have a Cal Alpha that puts out 2x to 3x more gain than my BAT cdp, and a tuner that falls right in the middle. Some preamps have input gain controls to level the input of all sources, which is a nice, if not audiophile approved, convenience.

Why do you feel that it is important to be able to open up the gain control further than you already are? Installing attenuators in series with the volume control only reduces transparency and detail. The only time such devices should be used is if the volume control ( aka "gain" ) is phenomenally touchy and hard to adjust for the desired listening level. If you find that the volume is constantly jumping from too soft to too loud by barely adjusting the gain, the attenuators might solve this. Otherwise, get them outa there.... Sean

I think you are under the impression that there is an increase in sound quality with a higher volume knob setting. Not true. Keep the playback volume level where you like it. It's determined primarily by your listening room and the distance to your speakers - any amplifier over 20 watts has the potential for being too loud for the average listening room. Your system in someone elses room "9-oclock" may be too high and in another's "3-oclock" may not be loud enough. By all means, get rid of the attenuators.

Most any amp will sound best wide open. Volume controls (Esp. cheaper ones) are rather non-linear at the lower ends of their ranges. So I can see why he wants to run it more wide open.
