Pass Labs INT-25 or equivalent in another brand

I would check in with Mark at Reno Hi-Fi and see if you can get a demo unit.

He doesn’t have any at the moment. A new one for 7000.00. 

I have the Luxman 590axII which is 30 watts pure class A, 45 into 4 ohms. Some reviews state after that it’s class B to 90. Great sounding. 

Just purchase a new INT-25 from Mark @Reno. 

Congradulations! I owned Pass designed amps and preamps for well over thirty years… he disowns and manufactures great equipment. It is incredibly reliable and is likely to perform flawlessly as long as you wish to keep it.
