Rogue Audio RP-1 DAC use

@thegreenline   I have a question.  If you use the same DAC (best on you have), can you tell the difference between the two different pre-amps?  Which one do you prefer?   What is the history of the RP1 - new or used, how old is it? 

I would think and from my listening, the RP1 is a bit tubby and while that sound is great, it may be relaxed enough that you don't here the minor differences between the dacs you are comparing.   The DACS you name are similar and built into other devices.  I expect them to be similar and average.  There may be other stuff you are hearing or not hearing given the dacs appear to be integrated with other devices.  

I have a Vault II and am considering getting a Schitt Yggdrasil. Was also looking at the Linear Tube Audio Aero DAC - little more $$.

My question is if I will see improvement from just using the Bluesound Vault as my DAC.

Thoughts, Experience? I bought the Bluesound to get rid of my CD's when I first started building my system. I heard it was a good option, now I'm looking to improve while using it to still serve as my streamer.

also, why do most people recommend the "Less is More" version of the Yggy over the "More is Better" version?

What I said was

If after getting acclimated to one DAC it all still sounds the same to you, you’re either not capable to hear the differences or your system is not revealing (it’s not RP1 cause it’s pretty transparent) and or your room acoustics are bad or all of the above. 

You chose to only use a part of my post. Taking into consideration what I said about associated equipment and room acoustics instead of leaving it out and labeling my statement a cliche isn’t going to help you or the OP. Stop taking things out of context. That’s bad form. 

@audphile1 "That's bad form".  Good one!    Bad form is doubling down on a useless post.  I left out " (it’s not RP1 cause it’s pretty transparent) and or your room acoustics are bad or all of the above."

  Are you saying that the room acoustics came in to play only after he switched to the RP1?  He could distinguish between dacs before he switched.  Look at @thegreenline  post above as a logical explanation.  It appears that being called out is bad form to you.
