@cming0038 Nice! If you’re happy with the resultant sound, that is what matters.
Having a reference system (or systems) and comparing gear over time will develop your ability to quickly pick out a specific component’s sonic disposition (warm & sweet or dry and analytical etc).
For me, the RP-9 was not warm nor sweet compared to the ARC Ref 6 or VAC Master or VAC Renaissance III (or even the older Rogue Athena and Hera). However, I did like its bass punchiness, and overall clarity & detail. To be fair, I may never have burned it in "fully". But the VAC's were sweet from hour #1 lol. Maybe Rogue should do some initial burn-in and auditioning like VAC does (if a VAC component doesn't make the cut in audition, it goes back to the line).
Your post is making think I should experiment more along these lines -- since I have a few nice preamps, headphone amps, and headphones at my disposal :)
