Onkyo has spruced up the middle of its receiver line with two new models, the $1,399 TX-NR929 and the $1,099 TX-NR828. Both are THX Select2 Plus-certified, with 135 watts of power per channel. Both include wireless streaming through WiFi of files up to 24-bit/192-kilohertz resolution from computers, NAS drives, and other networked devices. And both include Bluetooth so your daughter can stream the latest Justin Bieber tune from her iPhone.

Hot on the heels of its new midpriced receivers, Pioneer today announced two new 7.2-channel receivers for its high-end Elite line. The new receivers use the same Class D3 amp technology as the other Elite receivers, but at lower prices: $1,100 for the new SC-71 and $1,400 for the SC-72.
