The new Valvet E2 SE single-ended Class A solid-state amplifier is a revelation. Coming to market about a year after my review of the Valvet E2, the SE version exceeds the E2's audible performance in every parameter. Please see the older review for context. The special edition SE version takes all the E2's excellent performance and offers improvements in every area.

The new Wyred 4 Sound ST-750LE stereo power amplifier sounds far above it's price class. The technology includes Wyred 4 Sound's proprietary input circuit that is similar to the one implemented in their '10 LP'-rated STP-SE Stage 2 preamplifier. This is followed by the latest IcePower amplifier module. The base price of the amplifier is $1599.00.
