McIntosh announces the MA352-- a second integrated amplifier from the company featuring a hybrid design bringing together both vacuum tube and solid-state audio design principles.

The all-analog design has a vacuum tube preamplifier section powered by a pair of 12AX7A and a pair of 12AT7 vacuum tubes. The output stage is a direct coupled solid-state amplifier outputting 200W per channel into 8-ohm speakers or 320W per channel into 4-ohm speakers, making double the output of the previous McIntosh integrated amplifier, the MA252. Dual scale blue Watt speakers give an accurate power output readout for both speaker impedances.

Denon adds to its soundbar offering with a pair of premium options-- the DHT-S516H and DHT-S716H, both combining 4K HDMI inpupts with ARC support while building on the features founding the HEOS Bar and HEOS HomeCinema HS2 soundbars.
