favorite this post Yamaha HTR-5740 6.1 A/V Receiver: LIDC*, WBW, HMP, TDAS, and Remote - $79 (Round Rock) hide this posting unhide

Includes factory remote control.

- LIDC: Low Impedance Drive Capability. Unlike most other new models, this Yamaha is rated to operate into speaker impedances as low as 2-ohms so that it can correctly handle those “8-ohm” speaker that can drop to below 3.
* Even though most manufacturers state 8-ohm, in virtually all reviews of speakers by the leading audiophile magazine, it is recommended that the amplifier be 4-ohm capable.
- WBW: Wide Band Width. Unlike many new models, this Yamaha is rated at 10 Hz to 100,000 Hz (+0/-3 dB) – to correctly play 20-to-20, you need more than just 20-to-20
- HMP: High Music Power. RMS is mandated, but music is better. Although it is rated at 85 watts RMS from 20-to-20 into 8-ohms, under music tests it does:
2-ohms: 230 watts per channel
4-ohms: 185 watts per channel
6-ohms: 150 watts per channel
8-ohms: 115 watts per channel
- TDAS: it has Totally Discrete Amplifier Stages – just like ultra high-end amps have.
