Plinius 9100 vs Luxman L-505U

I had Plinius 9100. Believe or not, Rotel RA1520 sound
better than Plinius. There is no contest between Plinius
versus Luxman L505u. But again, everything is about synergy.
I have B&W 803S and JBL L100T3. My friend brought L505u in
my house and sound was amazing.

Interesting. Based on my experience, Plinius 9100 was better than some amps I have owned, including Musical Fidelity A308 pre-amp and amp, Marantz PM-11S1, YBA DT. 9100 sounds natural, organic, which I like.

Yup, indeed interesting. I found the older Plinius 8200 to clearly outperform an MF A308 integrated IMS, and this MF significantly outperformed a NAD and Rotel integrated, again IMS. The 8200 was later replaced by a 9200, which was even more superior in transparency. I believe the 9100 is sonically identical to this 9200. Having said that the new Luxman is very highly regarded, and looks handsome. It may come down to a matter of system synergy and taste between the two.
