 PA-1
Description: This is the preamp that has been advertised in Music Direct's flyers. Monolithic Sound is the company created by Dusty Vawter, formerly of Audio Alchemy. In keeping with the AA tradition, the chasis is smaller than your average preamp, yet it manages to have four inputs and two outputs (all single ended). The front of the chasis sports a rotary/detented switch for the four inputs on the left, a muting toggle switch near the center, and a volume/gain control knob on the right( as you rotate the knob clockwise, the gain is passive until the mark on the knob aligns with a detented 0dB mark which is at 12 o'clock, then the active gain stage takes over). A cool blue LED in the center glows to let you know the power is on (no power switch). Speaking of power, the power supply is in a separate chasis. A power supply upgrade is available, but this review was made with the standard power supply.

Moscode 402Au OLT stereo power amplifier Review

George is adamant about the fact that the Moscode 402Au is not just a tube gain stage slapped onto a solid-state power amplifier; rather, it is a tube amplifier with a MOSFET output stage.

Lowther’s DX-65 driver in the Teresonic Magus XR Review

A new driver from Lowther is real news. A new five inch driver is even rarer news, so it was with great anticipation that I waited on this pair of speakers to arrive.

Aune Mini Headphone DAC User Review

The unit arrived from China well packed and everything seem to be in place. No external abuse by the carriers. The only problem was the power supply it came with. The box came with a cheap step-down converter.
