you can indeed connect a sub to the pre outs on an amp

about the Luxman; it just happens that I own a R-800 myself!
I got it for free though (had some luck at a container park...)

for 50 euro's I'd grab it!, they are nowhere near the power of the amps you've been looking at previously, but they are very well built, excellent tuner, excellent phono stage, symmetric output stages, pretty beefy transformer for a 40 watt/ch receiver..;

I like the sound it gives with my large advents, it didn't have any trouble neither driving stacked advents, pretty dynamic actually, especially considering the somewhat lower power output compared to the super receivers built several years later...

I've had no experience with the sansui you owned, but it was a more powerful and later unit than the R-800, which is from '74.

For €50, I'd say grab it. They sell for 150 - 200 on the second hand market if you're lucky, 50 is a more than reasonable price, so if you decide to flip it, it's a win win situation

I'm going to recap mine during the summer vacation, and entirely clean it out, veneer the wooden case again , it's my daily listening radio system, and I never heard my advents sing like this with them , of course, my main system is in a completely different league, but yeah, you could very much say that I like the luxman!

I see you added me on msn, btw

Keep them spinning,
Bert.
