why do some systems need higher volume settings to sound good

[Nick B]

I've had systems that were TFL at 10:00 and others at 3:00.  It's a function of speaker sensitivity, preamp gain and power amp input sensitivity.  Whatever.

It matters not where the volume control is set.  It is just the representation of the overall system sensitivity/gain/sensitivity equation.

I had a system with a passive "preamp" that sounded awesome at 3:00 and not so much at noon.  We need to feed our systems what they want.

Thanks, Dave. Passive sounds crappy with the Hattor. Either the 6 or 9dB setting on it are fine.

I have never looked specifically for high sensitivity speakers. Maybe one of these days I will. But the JMR is a great speaker and I have a good chunk of change invested in it.

As it's the best sound I've ever had, I have little to complain about 👍

Where do you have the gain control on the Elvis set?  Holger recommended to me to set it at 12 o'clock and raise or lower the gain setting on the preamp to compensate.  The actual number on the preamp display is really irrelevant as you're looking for the best sound with the lowest noise. What that 12 o'clock setting on the Elvis actually makes the input sensitivity I don't know but I took his advice and have it set there at least during breakin.

Jack,

I have always had the gain control at maximum. I thought that would  provide the best performance and lowest noise. My system is very low noise as is. But I will play with the game control starting at the 12 o'clock position and see what happens.

If at the maximum setting you don't hear any tube rush then you're OK but if so I would back it down and increase the Hattor's gain to it's maximum setting.
