@inna "This thread was clearly started by non-audiophile."
I think you are correct. The more time I spend on Audiogon the less I think that I am an audiophile. But I'm okay with that.
@inna "The question makes little sense in real world and one never leaves the source and the recordings out."
Agreed. That's why I very clearly stated in the original post:
"Let’s assume that the CDP, DAC, streamer, server or TT are delivering an optimal signal of an optimal recording to the system."
@slaw "Personally, I'd rather buy lps than to sit back trying to think of a descent thread...….."
And yet, you see seem to find enough time between buying LPs to make negative comments that bring no useful content to a thread. Good for you. At least you've got your priorities in order.
