Preamp or DAC

@audphile1 

Honestly I really like the 07x  I think it is very resolving, has a very wide soundstage and separation of instruments is excellent. I have no complaints. I am just looking for a next level and I wanted to get opinions on which of the two components would yield the most change in sq. I also wanted to try some tubes with the other components in my system. But I do really like the 07x and I have read where many reviewers/owners think it has tube like qualities. I definitely recommend it and even if I were to get a tube preamp I am pretty sure I will keep the 07x.

What did you like better about the Benchmark and Holo Audio over the 07x?

@backdoor if it ain’t broke, don’t fix it. Keep the coda pieces. 
I’d just get a great DAC if I were you. Look into MSB Discrete, Bricasti M21 (has R2R and Delta Sigma plus different filter options). 
With Aurender N20 the best interface will be AES/EBU which would allow you to leverage the N20’s superb clock. I hope that’s how you connect streamer and DAC now. 

@audphile1 yes I am using AES/EBU connection currently and I too believe it sound better than USB or any of the others. I will take a look at Bricasti. Thank you for your input. Ultimately, you are more than likely right.

@backdoor I commented earlier about the Pass XP-12, but saw your question on the Benchmark. The LA4 was one of the other preamps I tried and I liked it a lot. Very resolving and also great for low volume listening. It is a bit on the cold side however, and I do prefer the Pass. I would put the LA4 at the other end of the spectrum from the 07x, detailed and analytical, in comparison to the warmth of the 07x. The Pass is somewhere in the middle.
