Hello Ferdi,
How cheap is cheap for you?
I have a couple of suggestion for your kitchen system - well, as far as the amplification goes anyway.
For around $300 or much less depending on where you look, the JVC EX-A1 is a really cool little unit. For this price you get DVD (DVD-A as well as video) playback, CD playback, aux input, amp, tuner, and speakers all in one little great looking and great sounding unit. Here is a link to the discussion:
http://www.audiocircle.com/index.php?topic=20223Mark also discusses the less expensive "executive" JVC systems, which I haven't heard.
I can also recommend the Sharp EX-111 amps that you've probably read about here on AC. This system sounds great, but you'll need to find speakers for it. Also, this Sharp system with speakers will be larger than the little JVC.
I love these two all-in-one systems because they sound great and are so convenient to use.
I give kudos, too, to the Kloss Tivoli Model 1 table radio, but at $99, it offers neither the performance nor features of the Sharp EX-111. It's just a one speaker radio with aux input. Great for what it is, but the Sharp is so much more for about the same price.
Don't know if this matters to you, but the EX-111 samples at 5.6mHz.
Best,
KT
