Class D amps are just a different type of switching amp and are not digital amps...this is a misnomer.

The 7700 is not a hybrid design at all but is a full differential A/B amp.

For the most part, I agree that it is well made, unfortunately I think they made some compromises to the power supply section of the amp that result in unwanted issues in some instances as has been noted in my review.

Personally, if you like the B&K, I'd stick with that unless the difference in price is large (>$500). You should be able to find them for at least $2250 if not lower.
