Probably pretty crappy. My opinion is that the vinyl crowd are mostly two camps, those who listen to it because the particular music is only available there and those who have deluded themselves into believing the distortions in vinyl are an improvement over fidelity. Obviously some have one foot in each camp.

Self delusion is OK I guess - everyone does it to some extent. For audio I personally prefer a more rational approach.

The digital amps I've looked at all had measureable levels of distortion that are possibly audible, at least they are not orders of magnitude below the threshold of audibility. So yes, until the technology improves that worries me.

Thus my question - has the technology moved to the point where the amps measure well, or is it more 'listening test' results?
