pre-newbie status here: stereomour kit is being shipped.

Have been reading the forums with great interest. There is some really good conversation and information here and have picked up some really helpful things to keep in mind as a novice solder slinger and builder.

Some builders build their Steromour as a power amp w/no volume control. Think I know about how this would perform since listening, with pleasing results, to a friends Paramour monoblocks in my system for a time several years ago.

The plan is to leave the volume control in the build. My understanding is running the Stereomour with the volume wide open (or nearly so) with a volume controled source like Logitech Squeezebox Duet is essentially the same as using Stereomour as a power amplifier. Is this about right?

I listen to music using Squeezebox about 90% of the time. Also use a CD player as a source.

Any thoughts appreciated.

Dee,

If you are going to use the squeezebox, I'd recommend leaving it's volume at 100% and using the colume control on the stereomour.  The digital volume control on the squeezeboxes is not a a dithering type, but one that drops bits so the signal quality will get progressively worse the more you turn the volume down.

HTH,

Jim

Correct. 

For those who are bothered by the notion, you can short the input/output of each deck of the pot together to make the pot truly just a shunt to ground.
