Desktop Harbeth p3esr Amp

I just bought a pair of Harbeth p3esr speakers for a desktop system. Near-field listening while I work - as part of work I'll be dictating using voice recognition. I won't be cranking the tunes.

I'm attracted to the iNova for the all-in-one package (DAC/pre/amp) and the space savings. The iPod dock could see some use. Will I be selling the speakers short with this amp??? The iNova costs about $1800. Any other suggestions?

Thanks
