I would have thought dac in the past. My vinyl rig limited to a rega rp8 so I guess an alright medium quality rig going into vertere stage.
a few years back I bought a project rs2 transport which suddenly took CD to a level on par with my vinyl. I swapped my chord dac for matching rs2 dac connected by IS2 (hdmi) which allows dac to reclock the transport.
straight away it was a no need to mess anymore. The dac also has ability to have valves in the chain but my Luxman class an amp and tannoy speakers bring enough lushness to the game not to bother. I think the cd player top end from marantz/luxman might be simpler but efficient alternatives.
