Best Amplifier & Speakers combo?

IMHO, if you want a future proof combo. 

Buy the Vandersteen VLR bookshelf with a Belles Aria Integrated. 

Albeit, a little more than your budget, but, you'll have a very capable system that can be upgraded as funds allow.

These little speakers don't get the press like the KEF's, but they can really rock when given the right input.

 I use them for my office system, and find them to be very capable or reproducing music that engages you.

I do understand that you have a budget, but...

Investing in a stereo system means knowing what you like and dislike. If you can audition the KEF's and any other speaker/combo, it will enhance your ability to make a knowledgeable decision. In fact, this way you'd be able to buy some/all of the equipment used, and save some money, too.

And, @stuartk, added some very good points to consider.

To answer your question, 🙄, I would go for option #2. I doubt you would need the extra watts. Go for the better speakers. Just my opinion. :)

Just out of interest, have you hear this equipment? There are different flavors at every price point ($1K - $100K). Choosing the one that really connects with you is what is important. There is not an absolute better… like maybe which car accelerates faster.

If you get powered speakers they will be a perfect match.

1 percent time use for what that system?
