Nice review! Wondering what JA means by this quote in the measurements section
"This [volume] control had a rather aggressive action, its 12:00 position reducing the gain by 32dB from its maximum!" |

So thinking about the quote above a bit more, does this mean that at 12 o'clock on the volume the gain will be 32db down from 0? Extrapolating does this mean that there is a lot of fine control from the 7 o'clock position to the 12 o'clock position? I listen at low to moderate spl and want a gentle gain taper to help fine tune the volume control.

Yes the volume control on the BP-17 Cubed is a Balanced control with extremely accurate left/right accuracy and most of the gain is between 10 and 1 o'clock. So people are use to volume controls having most of the gain at 8 to 11 o'clock and with our volume control some think that the preamp is not as powerful. On a preamp the output is always at full gain and the volume control turns the gain down (opposite from a power amp). So it could be argued that the volume control on a preamp full up is the best performance. james |

OK, a techie question - when you say most of the gain is between 10 and 1 o'clock, can I take that to mean the relative change in attenuation per degree of knob rotation is greatest in this 10-1 o'clock range? thx!

Nice review James
Confirmation that the BP-13 cubed has a very gradual volume taper. Exactly what I'm looking for! "The volume knob was at midway point (12 o'clock) but the volume level was still surprisingly low... [adjusting] the volume knob to two o'clock .... The volume was now, closer to my normal listening level." |
