Spatial Audio Raven Preamp

Yes, it is 64 step attenuator, and the first step is 00.  It should be screamingly loud by 50, and most listening levels should fall in the 25-55 range on most systems.  Is that not the case in your system?  63 would blow the speakers out of the baffle in my system

Don,

It is loud but not screamingly loud.  I just wanted too make sure I did not have a problem.  My speakers have a measured sensitivity of 91.5.  It is more than loud enough for me.  Thanks for the response.

I'd be curious to know your amps input impedance as at or near max attenuation would be very loud.

Any info on your power amps? Input sensitivity (volts RMS to clip the amp) and input impedance should tell the tale.

Transistor amps (with feedback) are typically 1~2 volts to clip amp, and input impedance is typically 10K to 22K.

The Bruno Putzey Class D modules are designed so they need they need about 10V drive and an input impedance of 6300 ohms. This non-standard input is intentional; it gives the third-party amp designer the freedom to design an input stage that has the tone color they want: op-amp, solid-state discrete, or vacuum tube.

My speakers are 89dB sensitivity and the volume on my Raven preamp at a "comfortable" listening level is 35.  Need those amp specs or something is amiss.
