I use analog L/R out for my headphone amps from my 568.2, you can't use mute so it's a schlep to have to turn the volume down to use my headphones.

Sorry to rain on Meridians parade , but I really can't generate enthusiasm for this product at its price point.

A pre without remote volume these days is useless, a USB only DAC is limiting, spatial processing is old hat and never took off and a 1200/2000 quid analog only headphone amp has a 1000 other competitors.

Roon/Tidal, SBT, Trinnov ST2 , Twin Devialet D premiers, Vivid Audio Giya G1 Spirits, dedicated and treated room.
Meridian gear: 568.2mm and DSP5000's acting as TV speakers.
