Sorry, but these days "consumer-grade audio power amps"
are all class-D. In general most of these can perform as
well as a linear amps. I have my favorites. Especially
high-performance ICs that are well represented in complete
PCBs from China, available at rock-bottom prices on eBay.
An example, IRS2092. This Intersil PWM IC has +/-100V range,
can be pushed to 1MHz, and provides 1A gate drive to a pair
of n-channel HV MOSFETs. A popular combo: a 250W amplifier
using an IRFI4019: two 150V, 6A FETs in a TO-220F-5 package.
E.g., eBay item 122463174432 for $20 + $3 shipping. These
can be DC coupled by bypassing the AC coupling capacitor.
This item, an L15DSMD 250W amp, is based on IR's IRAUDAMP7S.

Recommended supply with 8-ohm speakers, +/-50V. But given
the IRFI4019's rating, you'd want to stay under +/-65V.
Another combo, IRS2092 + two IRFB4227: 200V, 45A TO-220 FETs,
for a 1000-Watt amplifier, eBay item 222177230692, $63+$10.
