Sub $2,000 Integrated Amp Recommendations

Not bad options you have, OP. I would take a higher-end, used approach. The Music Room is an excellent resource, highly regarded vendor. For instance:

JBL, New

Some good choices on your list. I had the M3si briefly and liked it, but it did not enough power for my speakers. Take a look at NAD as well.

You might want to aim higher and troll the used market for a while, some great deals to be had on lightly used equipment.

Little Luxman, tube integrated, NEW, 10 wpc

I have this one in my office system, sounds terrific, you need efficient speakers.

Some Japanese items, like my JVC TT81 are 100v. You need a decent quality simple 120/100 transformer (i.e. nothing fancy or pricey needed, just avoid junk)

Hegel looks interesting
