Upgrade: Speakers or Amp. mod?


I have an Onix SP3 which I love. I recently decided to have it modified with better caps etc.
However, a pair of speakers have recently been put on sale at Audiogon which are the next model up from the version I currently own and also really like.
Which upgrade would you make? Should I have the amp modified or should I upgrade the speakers?
I cannot afford to do both now.
I await your replies.

Get the speakers, like Rsfphil said. The speakers are on sale now. The mod will probably be about a constant price.
Just to play Satan's attorney, there is one reason to consider the amp: speakers often sound better when the downstream components feeding into them improve.

However, it sounds like the speakers in question are sort of a rare find. So then you can look forward to *really* having phenomenal sound when you're able to afford the amp in teh future.

So ultimately I agree with the other posters, but wanted to at least mildly advocate for the other alternative.
