Cute names, but perhaps "fast", "high", "higher", "highest" or even a
numeric values be more obvious; especially to folks with a smaller
English vocabulary.

To me, hq/audiophile/goldenear might all be interchangeable.
The "dict" command on my system defines "hq" as Headquarters,
and doesn't even know about the other two.

Haven't had much time or interest in the rest of the series.
