Another test.

Hook SqueezeBox/Transporter direct to DSP Speaker.

Take a good 16bit sample and listen at 63 (on DSP Speaker Display)

Take your SqueezeBox/Transporter out of Max Volume Mode.

Lower volume by 36dB (6 bits)

Raise Volume on DSP Speaker to 99dB (+36dB).

It should still be getting all 16bits.

Bet you it sounds like crap (it should be no louder or softer). Because now your operating it the worst range of the DAC.

You could do the same test by using ReplayGain, or editing with Audacity.

- Fiddler (IMHO)

If you think listening to music is fun, try learning an instrument.
