PP,

Rick's was pretty much right on with what he said.

Now granted if you are listening to something that has 0.05% or 0.003% distortion, you may never hear the difference.

But feedback kills... this is why Solid State designers like Charlie Hansen and others that do not use feedback in their designs. Not only does it kill the staging it kills the life out of the music.

Ok now what is the down side of SS non feedback designs. Well there are freaken a ton of components, well compared to like one tube.

Remember with each stage of amplification something is lost. With a SS design like that you maybe talking between 12 and 40 separate transistors.

We don't need a bunch of gain here... most dac chips put out the correct 2Vac RMS... so what we really need is a good buffer. Well not more than one stage or a single triode is required for that.

Really I think your next step should be to try and hear the difference between a good SS DAC with feedback (opamp or discrete based) and a SS dac without feedback like the Ayre and then a tube dac.

Thanks
Gordon
