Hello Max. Welcome to AOS.
You've come to the right place if you want opinions and advice on vintage British Hi-Fi.
If you want to ask anything have a look at the Past Masters section, it covers this. You can just join in the chat if you like.
Just my opinion having owned a few of each, the Leak Stereo 20 is very nice, but the various Rogers Cadet variants are not in the same league and now overpriced.
The Leak also works very well with a passive pre-amp, which can help in keeping costs sensible.
Enjoy the forum,
Geoff.
It is impossible for anything digital to sound analogue, because it isn't analogue!
