TRL Dude, VAC, NAT Audio, VTL 7.5, Lamm, ARC


Has anyone compared the TRL Dude pre to the VAC Signature, NAT Audio, VTL, Lamm, ARC, or Jadis? Of these, the TRL and VAC sounds I am not familiar with. Would like feedback on is either of them sweet like the Jadis, or is it neutral and dynamic with good separation, and bass.
