While Sonist had a few tube amplifiers on hand, we listened to the Audion Sterling Silver EL34 Anniversary integrated amp ($3499), the Wyred for Sound Sonos sample-rate converter ($890), which converts i2S into 96kHz, up-sampled S/PDIF, and a Wyred for Sound 32-bit DAC ($1499). The DAC has a defeatable 32-bit volume control, 2 coax inputs, 2 Toslink inputs, 1 AES/EBU input, 1 balanced i2S input via HDMI cable, and a 24-bit/192kHz asynchronous USB input. All cabling was the Cable Research Lab Bronze Series.
