Digital Volume of Transporter (RE: article in June/July issue of TAS)

I did not know that the volume control in Transporter is in digital domain before I read nice review by Steven Stone
I have surround sound processor in my system, but my stereo setup is just plain from Transporter via balanced connection to my Parasound Halo A21 amp. I do not want to purchase analog pre-amp now anyway, I have only one stereo source to switch and I do not even have a space for another box!
Parasound has gain controls per every channel on its back panel. Can I use these to reduce the volume so I could drive the volume of Transporter to max?
BTW, how much is -10db that you specified in the article? The bar on the Transporter goes from 0 to 100, no?
What is the minimal safe volume I can use on Transporter without degrading the signal?

 If the Parasound has analog gain controls you can use it to lower the output from the analog outputs from your Transporter.
That's in essence what I did in my review.
-10 dB will vary depending on the inputs on your amplifier or preamp. My settings were determined by a level meter.
On Slim Devices forums site some users claim that they can lower the outputs of the Transporter by as much as -6 dB without audible degradation - YMMV.
