Hi Bachtoven,
I've been using the Int-150 for the last 5 years or so and never once did I encounter any problem whatsoever with this amp. Its so reliable and the built quality is as solid as a tank. Sound wise, I can't complain at all with this price, it gives me all the sonic quality that I need or want and more. Now, I'm just curious about Pass new INT-250. Anyone heard it yet? Would appreciate some feedback and comparison with the INT-150 if possible. That would be next target, after 5 years, the upgrade itch is in the air. Meanwhile, sit back and enjoy the Int-150, its a real performer that can give some of the separates a run for their money.
