Ia a good amp more important than a good DAC?

Sink your real money in the components which have the greatest prospect for longevity. Speakers and amp (integrated) if carefully chosen will last a long time. Sources seem to change more often as do formats and good ones are fairly easy to find and can be fairly inexpensive. Over the long haul, if you are careful in the amp/speaker selection, you can continue to improve your overall system by increasing the quality of your sources. That is what I would do anyway.

I agree with that posters above.

I remember running an entry-level AMC transport and DAC with my new Audio Space tube integrated and Triangle Titus ES monitors. It was just because I upgraded in that order--amp, speakers then source. I had thought the system was OK until I got the new downstream gear, but after that awww... I pretty much stopped listening, even for lullabies. The source turned out to be just too limited once I could hear it properly.

Listen to your present source with the amp you plan to buy, then try the other way round (new DAC and current amp). See which setup you think you'll be able to live with most easily while you save for the second piece.

I think you are right to try to make the choice, BTW, instead of spreading the money over two pieces of gear. It makes sense to upgrade big, not often.

I am in the source first camp.
You amp cannot fix what is not right upstream.

would I be peeing in the wind to use a great amp and a good but not great CD player?

Can you hold it for a bit longer until we get to a rest stop?

I'm in the source camp, and we have a little song we like to sing around the campfire and you're lucky you can't hear me sing it. Garbage in = garbage out. I don't want a great amp to amplify all the nuance and detail of a crappy source. Newbee, however, does, as usual, make a good point: digital front-ends and formats come and go like movie sequels. Amps and speakers stand the test of time like Robert Redford and Clint Eastwood. Then again, who knows how long you're going to live - why not get the best right now dammit!? That, or hang on to what you have and put your money into hookers, booze, vending machine prophelactics and cheap hotel rooms.
