but am intrigued by the hybrid DragoN's.Hi, look at my 3rd post.
Not really a hybrid, as it still has opamp buffers to drive the Hypex NC500 amp modules with, the tube buffers are added in front of the opamp buffers just to give sound "tube colouration".
Not too keen on this,
A buffer from your source (dac or pre), driving "another tube buffer" and it's driving another "opamp buffer" before the NC500 amp get driven.
Too many buffers 3 x in series all adding distortions and noise.
