I owned both the Pass Labs INT-60 and Luxman 509x for an extended period. In terms of pure sound quality, to my ears I liked the Pass better. Richer tone, fuller but seems to have a good grip on things and a ton of power in reserve. Luxman seemed leaner and was missing something. I liked the all in one box solution offered by Luxman (headphone and phono preamp, plus old school tone controls, loudness, meters, etc.) Like Erik says, you’ve got to hear them yourself and better yet in your room with your gear. My speakers are Zu Audio Definition IV, VPI Classic 3 tt, Innuos ZENmini w/LPS and Phoenix Reclocker, Border Patrol SEi DAC. Had a Line Magnetic 219ia before those two integrateds that had the best sound of all but was like the high maintenance super hot girlfriend.
Luxman 590axii vs Pass Labs int 60
Anyone had the opportunity to compare these specific amps? Both are "quasi Class A" amps. I auditioned the int 60 and was extremely impressed and even more so when hooked to the MSB ADC V. How does it compare to the Luxman 590axii? They seem to be in direct competition with each other. Which do you like best?
