For sale: Purity Foundation Buffer - hardwood chassis
« on: September 20, 2023, 09:02:55 AM »
For sale is a demo unit of our Foundation Tube Buffer. Single ended only. Built into a Paudak solid wood chassis with acrylic front and rear panels. This is the last of the hardwood chassis Foundation Series.
Perfect for use between preamplifier and amplifier, especially sterile sounding solid state. Can also be used between source component and preamplifier or installed in a tape loop in a home theater receiver to provide some of that tube sound throughout your system.
This particular model can use only one input.

Regular price $1,995
Selling: $1,199

Still available. A great addition to a solid state DAC. Currently used with Geshelli DAC.

This is the same circuit as the input stage of our HA200H hybrid GaN FET amplifier. A great circuit to put in front of any solid state or GaN FET amplifier with at least a 10k input impedance.
Accepting offers.
