The turntable's definitely the weak link. It's a cheapie but performs pretty well considering the cost. The issue here is my record collection -- not that large, and a number of the records were picked up used while I was in college in the '80s, and thus aren't in great condition. Just didn't seem to be worth spending lots of $$ there.
mjcmt recommended upgrading to the new pre, but since I use an external DAC, I'm not clear on the sonic advantages. The Nova 300 seems to be doing a good job, but I'm curious as to whether the new unit would be a worthwhile upgrade.
ricmech23, I liked the Nova 300, but the Gan seems warmer (love the tone), more detailed, and provides a more holographic soundstage. It was a good upgrade.
