Spend the money wisely and buy a good amp. Preferably a new one. Avoid pre-owned. Your speakers are very nice and very expensive.
Look for a good new Luxman. Through authorized channel's. Unfortunately McIntosh and accuphase aren't available through the right authority.
Don't get hooked into getting a used amp by someone giving ball talk and trying to pawn off something to you please.
With a brand new amp, you can't go wrong. Your speakers will need something nice and shiny. Lots of brand new tube amps available as well. Good audiophile brands. Spend once spend right. I'm an example of the other kind. Wrong spendings most of the time. Wish u good luck Vivek!
