A few days ago this beauty finally arrived from far away and after some hassle with the customs office
Here is my first impression 
It's mot exactly minty but the condition is pretty good. The antenna is not original and the wireless mic button has been pushed inside. Except from that there is only minor wear and tear. The contacts need a lot of attention. The bass and balance knobs don't do much unfortunately. Currently only one sound only comes from one speaker
Hopefully I can fix that when I open this box up. The belts need to be replaced as well.
Anyhow, I really like this National! While not ressembling that streets look the RX-5700 was designed beautifully! Lots of metal and chrome, unusual grills and big VUs
The (fake) wood panels definitely make the 5700 stick out. It's about the size of an M70, maybe an inch taller.
The built quality is just as good as the design. The knobs are extremely firm, the cassette keys don't rattle.
Despite the usual features you have a tape programm search and the fm wireless mic option I mentioned above. There's also a button to switch between level and tuner/battery but no light for the VUs. The radio scale goes from 76 all the way to 108
Now for the sound. And yes, it is just as good as everything else on this box. The bass is very good and only distorts at top volumes. There were some (very few) songs and tracks though in which the bass didn't come through that good. The highs are crystal clear at all volumes. It doesn't go super loud bit the overall sound is superb. And you have to keep in mind that I wasn't able to adjust the bass and that the sound only from one speaker so far.
In conclusion everything about the National RX-5700 is way above average and some aspects are even top notch. There are several bigger Nationals like the 7000, 7200, 7700 and 5350 which might tend to overshadow the (little bit) smaller and (well not that much) more common ones but the 5700 should be kept in mind just as much as those.
