The preamp and DAC on my NOVA 150 were the weak links from my tests. It was a good unit for the price but I did compare the preamp, DAC, and amp separately and it was clear to me that the amp section was much better.
I currently have a pretty good tube DAC, the AudioMirror Tubadour III SE which costs close to $3K. I like my half the price Gustard X26 Pro DAC more. It has NOS and OS mode with 3 custom filters that one can differentiate. I also like the Gustard more than my Benchmark DAC3B.
At the moment I am using a D-Sonic M3a 800s amp. It cost $1500 and it is real good. It is has a bit of warmth and is better than the amp section of the NOVA.
The Gustard X26 Pro + D-Sonic is a compete digital system. Though I would always add the Benchmark LA4 preamp ($2500).
