Better than expected!
Fantastic vacuum pump for the price. Beat its advertised rating. Was able to pull 15 microns.
Very fast evacuation of a 5 zone 210 foot system.

A very well thought out and designed product.
2 of 2 found this helpful I'm glad to see that Sony is back in the game with some new "Hi Res" products. This is a perfect match for the MDR-Z7 headphones. The design and build is first rate as is the sound quality. I like the choice of analog outputs (balanced, unbalanced and line level) and the variety of digital input options. At first I was a little surprised that the unit doesn't play off the USB power input (and only charges) but after realizing that the reason was to be able to operate off the pure DC from the battery without any power supply noise I felt better about their choice. I suspect that typical USB power supplies are of a much lower quality than what would be needed for high quality sound and building in an appropriate power supply would have added to the size of the unit. Overall I am extremely pleased with this DAC/amp!
