<font color='#000000'>From what I've read, there's no inherent advantage to discrete circuitry (the best modern integrated opamps are very good indeed) and Aussie has it pretty well nailed. Although, it is not hard to imagine that some makers are indeed skimping here and there. Even expensive big-name gear sometimes uses shamefully cheap parts where a better alternative could certainly have been used for the price being charged to the customer!
If (big if) they ever get the distortion problems of Class D and true digital amps ironed out, we're going to see a lot of small, light, powerful audiophile grade amps in the near future, IMO. As it is, Sony and some other makers are using Class D/digital amps in mass-market gear already for compactness, where the target buyer might not care about THD figures.
On a "high-end" board I sometimes visit out of curiosity, there's a lot of talk about a B&O (Bang & Olufsen) digital "ICE" module for amps. Hawke and Gene and the EE types here: any thoughts on that?</font>
