Portable budget system. Class D Audio

Question if she already has Schitt Audio pre why not one of their amp's Vidar probably best suited for her speakers and same price range as the Class D amp. not that there is anything wrong with Class D, though it is probably smaller.  

I have the SDS-470C and it has been great for the past several years. I would not use it with really sensitive speakers though as it is a bit noisy...not an issue with the Elacs.

I would also not use any of the Class D Audio amps with a passive pre since they need gain to come to life due to low sensitivity (2V input) and low input impedence. IMHO, the amp would not be a good match for that system.

Indeed, for a portable system I think going with a pair of active speakers would be a better solution. Especially something with a built-in dac like the KEF LSX or LS50W.

Thanks for the feedback.  Audio Adviser has a sale on Parasound New Classic 2125v2.  One is in shipment now.  I shared your concern about the passive pre/volume control. The Parasound should work well I think.
