Quad 22 upgrade DAC?

[malcolmfraser]

Hello all,

I am restoring a set of Quad 2 mono-blocks, and want to move the Quad 22 pre-amp to full digital to analogue (remove all the tubes etc).

Signal pathway will be Tidal Stream --> USB --> DAC --> Volume Control --> Tone Controls --> RCA Phono Out --> Quad 2 mono-blocks.

Any recommendations:

1. Suitable hi-quality DAC that will take USB and unfold MQA with best quality bit rate, minimum 24bit/196Hz
2. Precision rotary volume control suitable for the DAC
3. Preamp and Tone Control Board (Treble, Bass and maybe filters)

Thanks in advance.

Malcolm

Sell the quad22 and build your digital preamp in a suitable box.
